Hmm well in psuedo code i would do the fade away thing like this.

Struct Blood
{
vector4 bloodColorTrans = 0.0f,0.0f,0.0f,0.0f
Int DespawnCounter = 5

//And any other information you might need ect, like coordinates, size, ect //and a sturct constructor.
}

Blood bloodSprite = new Blood("path/to/sprite") //plus other consturct args

List<Blood> bloodList = new list<Blood>()

GameTime counter = GameTime.getSecond()

If(Bullet.Collision)
bloodList.Add(bloodSprite)

Foreach(blood in bloodList)
{
Draw(blood)
}

If (counter % 2.0f == 0) //
{
If (!bloodList == null)
Foreach(blood in bloodList)
{
If(blood.Counter > 0)
{
blood.BloodColorTrans = BloodColorTrans - vector4(0f,0f,0f,.2f);
blood.DespawnCounter - 1;
}
Else
blood.delete();
}
}

This is just a roughdraft of how i would start. (in C# hehe. )

Perhaps people should add on to what i put?

I have no problem with deciding when and where to place blood or their alpha value. I already have that implemented and it is working pretty well in a build that I have running on Windows using OpenGL for rendering (before anyone asks yeah I'll be releasing Windows versions eventually).



My problem comes when I get to that "Draw(blood)" part you mentioned.

This is what I've got now. It is imperfect when fewer then the maximum number of decals are in existence but whatever I'm content with it, it doesn't take long for 500 blood or corpse sprites to be spawned and I can improve upon it later.

#ifdef WIN
glBindTexture(GL_TEXTURE_2D,persontexture);
#endif
#ifdef PS3
usetexture(persontexture_image);
#endif
for(int a=0;a<decalcount;a++){
	#ifdef WIN
	glColor4f(1.f,1.f,1.f,(float)a/(float)maxdecalcount); 
	#endif
	draw2dquad(
		decallist[a].posx,
		decallist[a].posy,
		0.75f,0.75f,
		decaltexturecoords[decallist[a].type],
		1,decallist[a].angle);
}
#ifdef WIN
glColor4f(1.f,1.f,1.f,1.f); 
#endif

With this being the PS3 version of that draw2dquad function

void draw2dquad(float posx,float posy,float sizex,float sizey,float *texturecoords,bool centerandrotate,float angle){
	#ifdef PS3
	if(centerandrotate==0){
		float verts[]={
			posx,		posy+sizey,
			posx+sizex,	posy+sizey,
			posx+sizex,	posy,
			posx,		posy,};
		realityVertexBegin(context,REALITY_QUADS);{
			for(int b=0;b<4;b++){
				realityTexCoord2f(context,texturecoords[b*2],texturecoords[b*2+1]);
				realityVertex4f(context,verts[b*2],verts[b*2+1],0.0,1.0);
			}
		}
		realityVertexEnd(context);
	}else if(angle==0){
		sizex*=0.5f;
		sizey*=0.5f;
		float verts[]={
			posx-sizex,	posy+sizey,
			posx+sizex,	posy+sizey,
			posx+sizex,	posy-sizey,
			posx-sizex,	posy-sizey,};
		realityVertexBegin(context,REALITY_QUADS);{
			for(int b=0;b<4;b++){
				realityTexCoord2f(context,texturecoords[b*2],texturecoords[b*2+1]);
				realityVertex4f(context,verts[b*2],verts[b*2+1],0.0,1.0);
			}
		}
		realityVertexEnd(context);
	}else{
		angle*=-1;
		sizex*=0.5f;
		sizey*=0.5f;
		float vertsunrotated[]={
			0-sizex,	0+sizey,
			0+sizex,	0+sizey,
			0+sizex,	0-sizey,
			0-sizex,	0-sizey,};
		float verts[]={
			posx+vertsunrotated[1]*sin(angle)+vertsunrotated[0]*cos(angle),	posy+vertsunrotated[1]*cos(angle)-vertsunrotated[0]*sin(angle),
			posx+vertsunrotated[3]*sin(angle)+vertsunrotated[2]*cos(angle),	posy+vertsunrotated[3]*cos(angle)-vertsunrotated[2]*sin(angle),
			posx+vertsunrotated[5]*sin(angle)+vertsunrotated[4]*cos(angle),	posy+vertsunrotated[5]*cos(angle)-vertsunrotated[4]*sin(angle),
			posx+vertsunrotated[7]*sin(angle)+vertsunrotated[6]*cos(angle),	posy+vertsunrotated[7]*cos(angle)-vertsunrotated[6]*sin(angle),};
		realityVertexBegin(context,REALITY_QUADS);{
			for(int b=0;b<4;b++){
				realityTexCoord2f(context,texturecoords[b*2],texturecoords[b*2+1]);
				realityVertex4f(context,verts[b*2],verts[b*2+1],0.0,1.0);
			}
		}
		realityVertexEnd(context);
	}
	#endif
}

Yeah I know there is undoubtedly a lot of room for optimization especially when it comes to dealing with rotated sprites but the relevant part is that I obviously can't use glColor4f without OpenGL so I need a PS3 specific alternative.

Let me see if i can find what your looking for regarding the glcolor4.

[daveyp187]

I love this game
thanks for the update.

[jonnyjaeger]

Gonna try this one out as soon as I get home from work tomorrow. Seems like an awesome game. Thanks and keep up the good work!!

[cloneking666]

some one showed make like a postal game. but a lot cooler. and more blood-yer.

I just wish it had some music/sound effects
