Top-down camera

Hi! I'm not a programmer just play with the codes :). When I tried to do a top-down camera view in an older sauerbreten (mp edition), all models -playermodel, ammo pickup, hp... goes invisible, but the camera is work perfectly. What's wrong?

glMatrixMode(GL_PROJECTION);
glLoadIdentity();
int farplane = max(max(fog*2, 384), hdr.worldsize*2);
gluPerspective(fovy, aspect, 0.54f, farplane);
glRotatef(90, 1, 0, 0); //topdown camera
glMatrixMode(GL_MODELVIEW);
transplayer();

Thanx for the help... :)

Of course you'll get strange effects if you do it that way. The engine's culling functions (among with many other things) assume that camera orientation matches OpenGL view. You should try modifying camera1->pitch instead (for camera rotation stuff, look into rendergl.cpp, mousemove() or recomputecamera() would be a good starting point.

Ok. This solved the problem:
if(!isthirdperson())
recomputecamera();
camera1->pitch = -90, 0, 0;
cl->drawhudgun();
But now shoot down and not forward :(

If you want to shoot directly forward (always) you could try removing all player->pitch = ... from mousemove() and instead put player->pitch = 0 in there. Then you should shoot horizontally no matter what. You'll have trouble with editing, though.

Dude this would be pretty sweet if you made a couple maps from the top down perspective and modded the game so it could be played as such. Mod sauerbraten into a really fast top down shooter :D

Whohooo! I did it! - http://www.youtube.com/watch?v=gAga8JYkqsA - Million thanks for the help typhoon! The story now continues, I do the animation of one of my models...

That's pretty legit. It'd be amazing if this were officially supported.

Also, I don't know why this bugs me, but can you make it perfectly top down, instead of at an angle behind the player?

Yeah, this not problem, but like this bigger the field of vision ( look at the similar games: Babo Violent; Subvein...) and grants the chance to the enemy that let him get behind you :). I am playing more than ten years with multiplayer games, and with this the camera setting much more enjoyable. Anyway this only a hobby for me, and i don't think so that a project would be serious because I am not a programmer, and will not succeed alone...

Allot of programming projects are never completed.

If you ever want to continue this, I can help with all image pertaining things such as icons, backgrounds and textures. I also have allot of experience with the gui scripting language.

This is a good start/idea, if we, or you get a group together, this would be a relevant and cool mod.

in this case you better come up with something actually good and unified, and not half-assed mods. ;)

techically speaking this would not have to be a mod, you could just simply disable camera clipping and bang your done. Also if anyone is serious about moding cube .. i can help. Ive been following cube for years and know about everything there is to know about the code(save some of the rendering functions).

Technically it's a mod :). About what you talk it total conversion... This is NOT a public mod, only hobby for me.

A mod is referring to almost any modification to the game or game-play ( and other stuff, of course ). This would classify just fine as a mod.

Chasester_aka_you | 2011-02-04 17:53

What i meant was the MOD, could be induced into the game as of right now. aka you would not need to create a separate version of the game.
