2007 July

Ghoulsblade 11:39, 29 July 2007 (CEST) : we extracted/capsuled all the code shared between sfz, iris2 and other projects and put it into an external lib so we have it in one central place and don't have to merge changes back and forth every time. As the main part of the lib is the lua binding for ogre we decided to call it lugre : http://lugre.schattenkind.net

Ghoulsblade 01:11, 28 July 2007 (CEST) : i've been busy with work (and with watching a cool animee) this week, so i didn't find the time to write here...

Thanks to rookie1 from the freegamer forums it might now be possible to compile and run sfz on a 64 bit linux, but i can't test... He sent in a patch, i added it to trunk, and also fixed a few other things that might be troublesome in 64 bit. see this thread for details : http://freegamer.schattenkind.net/index.php?t=msg&goto=111 I also squashed a few bugs, cleaned a few things along the way, and made a new win32 exe, so you might want to run the updater if you were having problems.

To clear up misunderstandings about the "as long as" in my last post : We will implement some form of spacefolding travelspeed and possibilities to interrupt it, but i think we need to focus on other things first, see this thread for an interesting discussion about the topic : http://freegamer.schattenkind.net/index.php?t=msg&th=11

There is a lot of code being shared between iris2 and sfz, and soon also by a third game-project by hagish and ray, so we will probably extract that code into a seperate lib to avoid having to merge new stuff back and forth every time. It's mainly a lua wrapper for the most important ogre parts as well as several utils for networking and similar things.

Ghoulsblade 02:01, 23 July 2007 (CEST) after thinking a while about space-folding travel and all the things to be considered when implementing it, i came to the conclusion that we don't really need it yet as long as the planets are so close together and not on a realistic scale, and other things like trading and missions are more important right now, and those usually involve traveling to other star systems, so i started a bit with the code for a list of star-systems

Ghoulsblade 00:33, 21 July 2007 (CEST) experiments with simple engine-particles

Ghoulsblade 20:00, 20 July 2007 (CEST) : screenshot of two new models by isha :

hagish 18:14, 16 July 2007 (CEST) : now laser and explosions have sound effects if you activate it in the config

Ghoulsblade 17:31, 16 July 2007 (CEST) : win compile was successful, so we now have a new binary released :

win32-binary (build 489, ca32 mb)

you might need to install this before it works: Microsoft Visual C++ 2005 SP1 Redistributable Package (x86) : http://www.microsoft.com/downloads/details.aspx?FamilyID=200B2FD9-AE1A-4A14-984D-389C36F85647&displaylang=en

in the initial setup dialog, choose directx instead of opengl otherwise it crashes for an unknown reason so far.

it includes an updater.exe to get the latest code changes, and as we are working mainly on the lua code which does not need to be compiled, you can get the latest changes this way even if we don't make a new release for a while. A new binary release will only be needed if there are changes to the c++ code, which are rather rare. Please note that sfz is still work in progress and there isn't any real gameplay yet, just a few things to try out =)

Ghoulsblade 02:46, 16 July 2007 (CEST): i successfully compiled and modified the iris updater for sfz, but it is useless until we have win binaries in the svn. i'll try to compile some using the project file by pascal in the next few days.

Ghoulsblade 20:11, 14 July 2007 (CEST) : we now have our own forum, thx to charlie aka FreeGamer for hosting us !

Ghoulsblade 05:48, 14 July 2007 (CEST) : another coding night with hagish and lots of stuff done. we can now walk around inside the ship and place several furniture items and stuff like doors, ladders, grates, engines, and it even works well over network =)

Ghoulsblade 00:14, 12 July 2007 (CEST) : i'm currently busy learning and writing tests for my studies, so i won't get to do much until the end of next week.

Ghoulsblade 19:04, 9 July 2007 (CEST) : hagish skinned the space-suit and the generator :

Ghoulsblade 19:41, 7 July 2007 (CEST) : enhanced the interior mesh generation a bit more, holes should be fixed now, some fine borderlines and a little tweaking of the ambient light vector greatly improve the spatial awareness, and i changed the firefly model to look better from the inside.

Ghoulsblade 03:41, 7 July 2007 (CEST) : experiments with walking around inside space-ships have begun, it's flying rather than walking and there is no collision detection so far, but we've got the inverted ship-mesh with inner walls removed. also hagish made a few nice 3d models : a space-suit to avoid billboard troubles, a couch : one of mankinds greatest achievements which should be aboard every starship, and a engine/generator like model that we'll use for various machinery, being able to hue/recolor meshes via lua code sure multiplies the uses for a new mesh :)

hagish 02:36, 7 July 2007 (CEST) : another coding night :)

Ghoulsblade 19:56, 6 July 2007 (CEST): we're currently working on a "location" system, that enables us to move objects to seperate "dimensions", for example to avoid destroying a fighter-object when it is docking, it is simply moved to a seperate "hangar-dimension". these things can later also be used for walking around inside spaceships (we're also working on generating experimental interior meshes for that) and for wormholes, etc... such a "dimension" has nothing todo with fancy graphics, it's just a logical grouping of objects so coordinate systems can overlap without objects interfering with each other. this isn't quite finished, the hudmarkers and other things still have to be adjusted. the current "hangar dimension" is nothing more than a gray empty space so far =)

Ghoulsblade 23:41, 4 July 2007 (CEST) : player now starts with a bigger ship and can launch from it in a little fighter and dock back on if they wish. meshes and gui for this are still very simple, but the code behind it works and can now be cleaned and extended.

Ghoulsblade 02:02, 4 July 2007 (CEST) : it is now possible to exit the current spaceship and float around in a space-suit, you can also enter ship. but there is a funny bug : i did put a check in to ensure that you couldn't enter pirate ships, but i forgot to check if the object to be entered is actually a ship, so now you can enter anything (except pirate-ships) and fly around as an asteroid, as a space-station or even as a wormhole :)

Ghoulsblade 19:36, 3 July 2007 (CEST) we've got a billboard space-suit ! so i guess we'll soon add something to enter and exit spaceships

Ghoulsblade 18:19, 1 July 2007 (CEST) i reorganised the object code a bit in preparation for buying,selling and installing equipment

2007 June

Ghoulsblade 03:12, 30 June 2007 (CEST) : now we have text next to the hull and shield meters, especially the distance info to the selected target is useful. also the right-click-menu has gotten a few useful new items.

Ghoulsblade 19:59, 29 June 2007 (CEST) : just moved the branch we were working on back to the trunk, so if you have been using the branch please change your svn path to

 svn checkout svn://zwischenwelt.org/sfz/sfz/trunk

i made a simple cargo dialog you can see what cargo you have, and can jettison it if you don't need it. also it's now easy to add tooltips to gui elements, and i have done that for the shield and hull-meters already. (see left-top, the mouse isn't visible on the screenshot)

Ghoulsblade 00:57, 28 June 2007 (CEST) : real live will keep me from coding until friday, i just dumped a few ideas here : Ideas_mission_planets

Ghoulsblade 23:08, 26 June 2007 (CEST): players can now collect cargo, currently this is only iron from destroying asteroids and pirates, stations can now offer services (available via right-click-menu when you are close enough), currently only repairing the ship, which costs iron =D

Ghoulsblade 17:56, 26 June 2007 (CEST): we got shields, and we got fancy hud meters for shields and hull status of your own ship (left-top) and of the selected target (right-top)

Ghoulsblade 23:37, 24 June 2007 (CEST) : hud : object markers : colored edges around objects

Ghoulsblade 22:37, 24 June 2007 (CEST) : finished cleanup and extension of code used to track 3D elements with 2D-HUD-gfx, now we've got the basis for fancy hud stuff like edges around objects and text next to them.

Ghoulsblade 23:45, 22 June 2007 (CEST) : gui and input system cleanup is finished so far, just the cursor stuff that was in the old gui code has to be reactivated, but thats not much. New context/rightclick menu implementation, supports easier creation and nested submenus.

Ghoulsblade 22:24, 21 June 2007 (CEST): there is a forum thread about sfz in the freegamer forums in case anyone wants to talk about it =)

Ghoulsblade 22:55, 20 June 2007 (CEST) : we're currently cleaning up and improving the input and gui systems, especially event-handling. i also started writing a little developer documentation about the input system, but its still work in progress, see DevDoc:Input

Ghoulsblade 00:18, 17 June 2007 (CEST) a simple experimental rightclick menu can be used to activate a simple approach/follow autopilot

Ghoulsblade 19:41, 16 June 2007 (CEST) : targets can now be selected via mouse-click, that makes destroying asteroids easier.

Ghoulsblade 02:28, 16 June 2007 (CEST): first experiments with 3rd person cam

Ghoulsblade 13:54, 15 June 2007 (CEST): After experimenting a bit we decided against making sfz combat based on fast reaction time and dogfight navigation, which quickly leads to frustrating "where is the enemy" problems. Instead weapons won't have to be aimed manually, they'll work like turrets, and if the enemy is in range you will be able to hit him without effort.

The deciding factor in combat will be stuff like weapon ranges and strengths and weaknesses of different weapons against different shield-types, homing missiles and counter-measures, maybe also a bit of energy management. This makes positioning, tactics and equipment a more interesting component.

Therefore a 3rd-person perspective of your own ship will probably be better than 1st person, for getting a better overview. This also fits nicely with the ship-editing features, because if you designed your own ship, you will want to see it =) Another benefit is that this makes it easier to use the mouse for gui stuff during combat, as there is no more need to use the mouse as joy-stick-like aiming tool, like in 1st person. So we can use the mouse for clicking on a target list, display tooltipps over hud-elements, and configure weapons and autopilot maneuvers with a proper gui using the mouse instead of dozens of key-combos like in most 1st-person-joystick space sims.

The massive multiplayer spacegame eve-online also has a similar gui to what we are aiming, I tried it some time ago and it had some interesting gui (ingame web-browser, 3rd person stuff like described above, target lists, cool map) and some nice gameplay elements (frequency crystals for weapons, buildingplans for equipment, most stuff could be crafted, also weapon ranges were very important) but it sufferes from being massive multiplayer and having rpg elements, e.g. you needed skills to do stuff and training a skill takes hours or even days, also death there means you loose equipment that took days to get, so people tend to be rather careful when and what to fight.

This leads to lots of ressource grinding, which i personally don't like too much, as it eats so much time. By not going massive multiplayer, and focusing on coop instead, we will try to avoid these problems.

Ghoulsblade 23:44, 11 June 2007 (CEST) code is now online (not trunk, but branches/eihortport)

hagish 14:46, 10 June 2007 (CEST) friday night ghoulsblade and i worked on sfz. due to a lack of internet (his t-online router sometimes acts a bit bitchy) the current code is not online but here are some screenshots. you can now fly around kill each other using the custom ships. the satellites with the green lasers are a first test of tower-defense like "towers".

Ghoulsblade 23:00, 7 June 2007 (CEST) pirates hunt the player, and player laser can now damage and destroy stuff

Pascal 08:27, 6 June 2007 (CEST) : Pulled actual source through VC 2k5 EE. Shooting pirates seen on a Windows XP flagship. :-P

Ghoulsblade 23:39, 5 June 2007 (CEST) : pirate attack ! they don't move yet, they only turn towards the player and start shooting lasers when he comes close enough, but lasers don't do damage yet =)

Ghoulsblade 09:38, 5 June 2007 (CEST) our sourceforge project has been approved =) soon we'll have a nice mailinglist (6-24 hours)

Ghoulsblade 22:54, 4 June 2007 (CEST) : experimental colored hud-text for all objects

Pascal 17:30, 2 June 2007 (CEST) : first working version of sfz-editor under Windows XP with MS Visual Studio 2005 Express Edition successfully created. Without sound support.

Ghoulsblade 13:30, 2 June 2007 (CEST) : network code is proceeding nicely, netmessage system with format and size checks is in place, udp works, resyncs are sent, received and handled, and the plugin system is also starting to take shape.

2007 May

Ghoulsblade 03:29, 28 May 2007 (CEST): first network experiments, tcp-connection was established and chat-text was successfully transmitted.

Ghoulsblade 04:33, 20 May 2007 (CEST): "intelligent guessing" mode for shippart placing is working, we just have to optimise it a bit as it gets rather slow when there are may shipparts on the scene. also load and save is now possible, the filebrowsing dialogs are just very simple so far, but its a start =) here's a ship hagish just made in a few minutes :

hagish 04:35, 20 May 2007 (CEST) upgraded the fmod sound code from fmod3 to fmodex. full ack, the ship editor is totally shiny :)

Ghoulsblade 22:09, 19 May 2007 (CEST) placing parts in the shipeditor is slowly getting more intuitive, parts are placed by selecting a part type and clicking on the side of an existing part of the ship in the editor window.
the algorithm for calculating the best position starts to work, but finding a good rotation/mirroring needs still a bit of work when the parttype being placed is different from the parttype that was clicked. When this is working we will create tools for putting different skins on the parts (eg. solid metal, window,...) and applying color.

Ghoulsblade 02:01, 16 May 2007 (CEST) : some experiments with calculating a voxel grid from convex mesh-shapes, will be used for intersection testing in shipeditor.

Ghoulsblade 17:31, 12 May 2007 (CEST): experimental mirror tool working, added ramp and pyramid with z-length = 1

Ghoulsblade 14:51, 12 May 2007 (CEST): implemented ramp primtive using the texture hagish made

Ghoulsblade 03:17, 12 May 2007 (CEST): we planned a lego-like intuitive placement system for spaceship parts, experimented a bit with geometry generated via code, hagish made a "cockpit-window" texture, and we tried a cubemap-skybox-reflection on it, looks nice in motion.

Ghoulsblade 19:31, 11 May 2007 (CEST) : hexagon mousepicking is working now, i also made the algorithm to generate them generic to make cone-shapes that might be used as simple cockpits and engines with a few nice textures. (one of them looks like a nice escape pod, another already gives the impression of a heavy freighter)

Ghoulsblade 13:48, 11 May 2007 (CEST) started experiments with prism shapes, hexagons look good as building block, but mousepicking isn't working correctly yet.

Ghoulsblade 22:22, 10 May 2007 (CEST) ship editor now supports different part types (just a few coloured test boxes so far), object-types now support "hueing" : the original asteroid is gray, the brown color is applied via code, also we have simple laser-beam-thingies now =) i also cleaned up the wiki a bit.

Ghoulsblade 00:22, 9 May 2007 (CEST): first experiments with an ingame ship-editor have begun, just now its just colored boxes, we'll have spaceship parts instead of them soon.

Ghoulsblade 23:52, 2 May 2007 (CEST): added lighting to mainmenu background scene, looks a lot nicer =)

Ghoulsblade 12:19, 1 May 2007 (CEST): it has been quiet here since we've been busy coding on http://iris2.de, but now we also resume work on sfz. currently we're working on the svn branch branches/eihortport until it is somewhat playable. we can reuse lots of code created and refined in iris2 for sfz, and we upgraded to the new ogre version eihort. now we have a nice main menu, and code for udp-networking is also done, but still has to be tested, that should speed things up a bit, as we plan to use two connections : tcp for important events that can't be lost and udp for highly redundant realtime resyncing for nice multiplayer.

2007 April

2007 March

2007 February

2007 January

2006 December

we started a little mod using the 2d ingame graphics from a friends browsergame xotus (http://www.xotus.de/)

2006 November

Ghoulsblade 19:00, 8 November 2006 (CET) : it has been a while, i worked on iris with science, have a look : [[1]]. iris and sfz use a common codebase, both build on ogre3d and lua, so both project benefit from each other. For sfz, i just started preparations for using multiple scenemangers, so we will be able to do RTT (render to texture) soon, which is needed for a nice 3d map in the hud.

2006 October

2006 September

Ghoulsblade 01:34, 11 September 2006 (CEST) : repaired collision detection and pirate ai

Ghoulsblade 20:49, 10 September 2006 (CEST) : target indicators fixed, f-key cheat disabled, "jump" menu available when far enough from system center. Location creation is now handled via a map-file-loader, different skyboxes and fog settings are possible. Collision and radar are still broken as well as the pirate ai for target picking.

Ghoulsblade 20:13, 9 September 2006 (CEST) : location system is working, in the current svn you can teleport between our first 2 test-locations using f1 and f2. Known bugs : collision and radar isn't working, and the hud-target-indicators still show objects outside the current location. Will be fixed soon.

Ghoulsblade 01:33, 8 September 2006 (CEST) : location systems starts working, some heavy code restructuring has just been finished, and although collision detection is still broken, we definitely moved forward. Beware that this evenings svn commit is still work in process, and might be unstable, but it compiles and runs, and i gotta sleep a bit now. Nothing new is visible yet, as there is no ingame command to change locations, but the code structure is ready, so we should see some basic traveling features any day now.

Ghoulsblade 01:27, 8 September 2006 (CEST) : a few points are still open, but the hud is basically functional, and work on the location system (which is mainly used for travelling) has started, so its time to move on to the next point on the roadmap

Ghoulsblade 18:37, 6 September 2006 (CEST) : been busy starting the iris and zw rewrite, but now also working a bit on sfz again. Next thing planned are locations, eg. traveling between different places instead of just the one lame old asteroid field, but it'll take a while as this is a major design decision, so we have to plan carefully.

Now there are multiple locations, and you can travel between them by "jumping" when you are far enough from the current locations-center. For now jumping is instantaneous and without any visual effekt. But fog stuff and different skyboxes look nice, so here are some screenshots:

2006 August

Ghoulsblade 14:47, 15 August 2006 (CEST) : After long silence (the end of the semester, lots of tests, and a lot of guildwars to save our sanity) things start rolling again. I'm currently cleaning up a few things in the code that have mutated a bit while experimenting with them, and the lua interface.

2006 July

Ghoulsblade 16:27, 3 July 2006 (CEST) : jehaww, the text element for our gui system is ready

the basic drawing primitives (clippable panel with borders, clippable text) for our gui system are starting to work

a radar (lower right of crosshair) and a radial grid (big circles and lines to objects)

2006 June

Ghoulsblade 23:05, 1 June 2006 (CEST): it's been quiet but we have quite a bit of progress, just no time to write about it, speedlines have been added to give visual feedback for own velocity, the hud-element-system has been made completely scriptable, and we just found and fixed the "crash on ship death" bug under win, so a more playable win release should be available soon. I also just made a "buyzone" near the space-station, that shows a hud button when the player is within, still todo is to actually be able to buy something (just weapon upgrades for a start) and getting destroyed enemies and astaroids to drop something collectable to give the player cash to buy things with =)

Ghoulsblade 23:19, 1 June 2006 (CEST) i changed our roadmap a little, now trading (at least equipment) is on our current milestone...

Ghoulsblade 08:14, 19 June 2006 (CEST) : we tried CEGUI but didn't really like it, so we are currently working on our own little GUI-System. It will probably feature html-like dialog-specification-syntax, so custom dialogs can be sent from the server, strong lua integration, and customizable layout-handling.

Ghoulsblade 23:22, 29 June 2006 (CEST) : after playing (too much) guildwars, i finally completed the border-color-clipplane-thingie, a graphical element that will be used intensly by our gui, it can be coloured freely, even colour-transitions from the edges, supports clipping (for parent-child hierarchy and scrolling later on) and consists of 3x3 parts (middle + borders), where each part can use its own set of texturecoordinates, and the middle can have a seperate texture from the borders, e.g. something tilable.

2006 May

we got stars, and speedlines

2006 April

Ghoulsblade 17:56, 24 April 2006 (CEST) : sorry, it has been quiet lately, i have been (and still am) busy porting iris (a 3d client for ultima, see [[2]]) to the ogre3d engine, so far they have been using a homebrewn engine. My port is far from playable and only a rough test, but i couldn't resist to upload a few screenshots, see IrisOgreScreenshots

Ghoulsblade 13:37, 17 April 2006 (CEST) : After a full day coding with hagish, we have lots of cool new stuff, hud target info and aiming help thingies, simple but damn cool physics (try playing pool(billiard) by ramming asteroids) and even ingame dialog windows (for entering playername and such)

Ghoulsblade 23:39, 15 April 2006 (CEST) : sorry, i've been a bit quiet these past days, needed to clean a few things up before starting work on the HUD (using ogre input system now, smartptr and listener improved, c++ timer class implemented) but now the HUD is started, and we have a simple crosshair, more will follow soon =)

Ghoulsblade 20:05, 11 April 2006 (CEST) : worked a bit on shots and explosions, looking quite nice now i think (3 new screenshots), still not animated though, screenshots can be made ingame by pressing "f", dumped particles from this roadmap, not really needed currently, so now we are done with milestone number 2, jeeehaww !

Ghoulsblade 00:27, 11 April 2006 (CEST) : cleaned up the code a bit, improved the "beam"-primitives cam-adjustment, explosions now have a real billboard, firing while mousebutton is down, drawing spheres for debug is now possible (ClientSetEllipsoid)

Ghoulsblade 04:20, 10 April 2006 (CEST): after one afternoon coding with hagish, we got lots of work done, see svn-log, and just now i upped a few Screenshots, enjoy =)

Ghoulsblade 14:48, 5 April 2006 (CEST): things continue to go smoothly, the first "experimental, non-detonating, ogre-head-shaped seeking missile" is targetting the player. I just rearranged the roadmap a little, hud was moved to the next release, and this milestone is now focused on weapons and destruction

Ghoulsblade 00:20, 4 April 2006 (CEST) : i like lua, now i already use it to controll most of the server & client message transfer as well as object creation, and integrating newly joined clients into the server... really a powerful scripting language. If this continues to go so smooth, we might have missile and other weapons sooner than expected. It is not the time for funky graphics yet, though...

funny stupid trails and shiptrails

worked a bit on explosions...

The first screenshots of V0.2, asteroids (can be destroyed / big ones split) "beam" primitive for something-like-billboard-line like bullets non-animated sample explosion damage instead of instant kill totally dumb ai-ships (just constantly firing and flying towards player) no fancy graphics yet, but at least there is more on screen

hud stuff, target indicators and such

2006 March

Ghoulsblade 00:10, 31 March 2006 (CEST): After a little coding pause (learning about Lua, playing guildwars and iwar2, planning how to use lua for various things...) i started integrating Lua, i am really suprised about this scripting-language =)

Ghoulsblade 00:14, 14 March 2006 (CET): direkt hit weapon is now working, other ships can be killed per mouse-click. They just disappear though, no visual ray or explosions yet. However that finishes our first milestone, now the work on sfz0.2 can begin =)
See also Screenshots , it's still ugly though....

Ghoulsblade 02:28, 11 March 2006 (CET): almost done, network runs fine, only weapons are missing now. the graphics are still ugly of course.

The first screenshots of V0.1

• 

  really ugly graphics, but enough for testing network and hit detection

• 

  one deadly mouse-click-shot later (with no visual weapon feedback yet (no visible ray, no explosion))
