 |
|
I'm trying to mess with fog in a opengl game
enabling it is easy, glEnable(GL_FOG) is just:
push 00000B60 / GL_FOG
call dword ptr [xxx+54180] / glEnable
changing density is easy too, glFogf(GL_FOG_DENSITY, 0.05.f):
push 3d4ccccd / 0.05
push 00000B62 / GL_FOG_DENSITY
call dword ptr [xxx+542F4] / glFogf
you get the idea, but the problem is changing the color: glFogfv(GL_FOG_COLOR,FogCol)
FogCol is an array of 3 values, that looks like
float FogCol[3]={0.8f,0.8f,0.8f}
how do i do that in assembly?

Try this,I don't know if it will work,but you push a pointer to the array:
| Code: | alloc(array,16)
array:
dd (float)14 // Value #1
dd (float)16 // Value #2
dd (float)11 // Value #3
injectedcode: // The address where you do the call
push array
push GL_FOG_COLOR // of course,modify this
call glFogfv |
Here is an article about Arrays in asm:
