Making a Space Shooter game

[leonardoaraujo.santos]

Hi , does someone knows how can I make the space effect in a Space Shooter games... Those stars in horizon that you never reach?

And about flying? I just make a camera move behind the cockpit?

[Joe_Oliveri]

I would say Build an unreachable sky box. That way no matter how far you are off the ground you are it will look the same.

or make sky sphere, which you can call star sphere. Should be simple sphere with polygoons facing inside or backface culling turned off. Apply star texture on it and keep it centered around your camera.

About flying and camera look here:

So this sphere should have a texture of the stars and it has to move with my spaceship... and all of moving objects (Another spaceship, or planets) would just enter in this sphere when they come close?

How can I make a sphere with polygoons facing inside?

And about the HUD? It´s simple to make some kind of Radar?

[arras]

Yes.

How can I make a sphere with polygoons facing inside?

Depend on 3D modeling program you use. Look at its manual.

And about the HUD? It´s simple to make some kind of Radar?

you can use 2D drawing functions like draw2DPolygon in video::IVideoDriver class or you can create texture, update it in real time and eighter draw it on screen as 2D or put it on some 3D object.

Thanks guys! Another questions. I`ve searched the forum and found that is simpler to create a space dome using ISceneManager::addSkyBoxSceneNode

But if I want to use particle systems do make this effect? How can I do it?

[monkeycracks]

smgr->addSkyDomeSceneNode(...);

Check the docks for more information, only requires a texture.
Alternatively you can use addSkyBoxSceneNode(...);

But thats if you have one for top, bottom, left, right, back, and front

Thanks Monkeycracks, its realy easiest to pass only one file.

Talking about the particle systems way, I found a code that emulated rain using particle systems?

Do you know how can I use particle systems to make the stars dome effect?

Oh ... the code for the rain is here (Maybe the stars effect is done with a particle system without gravity?)

Well the stars will never be reached right? They'll always be a part of the background.

And if they are reached you're ship would burn to pieces and die anyways

Search online for a seamless star texture and use that in skydomescenenode

Otherwise, if you're doing a 'hyerdrive' or something of that sort just make a particle emitter at the front of the ship emitting stars towards the ship to make it seem like the ship is 'moving' through them.

Thanks again monkeycracks I will try to find some cool space-ship mesh and I will do some research on shooting ....

Do you have or know about some code that I can use to start?

I saw aras sample and found awsome but I want to make some cockpit hud
