I have no idea what happened to it, it was running like a dream, fast and clean then suddenly I change one thing and it dies, and changeing the one little thing back does not fix it, I'm thinking I might have to start back from the base code that wasn't working
I am so befudlled
incedently the new culling and rendering code is
void cull_def_points( decal *dec){
//first compare every point in every polly with every point in every other polly
//and if they are at the same place make them the same point
for(int i =0; in_poly; i++){
for(int k = i+1; kn_poly; k++){
for(int g = 0; gpoly[i].n_point; g++){
for(int h = 0; hpoly[k].n_point; h++){
if(
(dec->vert[dec->poly[i].point[g]].xyz.x == dec->vert[dec->poly[k].point[h]].xyz.x) &&
(dec->vert[dec->poly[i].point[g]].xyz.y == dec->vert[dec->poly[k].point[h]].xyz.y) &&
(dec->vert[dec->poly[i].point[g]].xyz.z == dec->vert[dec->poly[k].point[h]].xyz.z) )
dec->poly[i].point[g] = dec->poly[k].point[h];
}
}
}
}
//now go through and find every point that isn't used
int end_points = 0;
bool *p = new bool[dec->n_def];
memset((void*)p, false, dec->n_def);
for(i =0; in_poly; i++){
for(int g = 0; gpoly[i].n_point; g++){
if(!p[dec->poly[i].point[g]])end_points++;
p[dec->poly[i].point[g]] = true;
}
}
vector *new_def = new vector[end_points];
Assert( new_def );
//copy all the used def points and update those pollies that refrence them
int k = 0;
for(i = 0; in_def; i++){
if(p[i]){
new_def[k] = dec->vert[i];
for(int g = 0; gn_poly; g++){
for(int h = 0; h< dec->poly[g].n_point; h++){
if(dec->poly[g].point[h] == i)dec->poly[g].point[h] = k;
}
}
k++;
}
}
delete[] dec->vert;
dec->vert = new_def;
dec->n_def = end_points;
delete[] p;
}
and
void decal_render_all(object * obj){
#ifdef DECALS_ENABLED

}
neither one of these should be screwing it up, and I'm sure there fine becase decals are being created with 0 pollies (this is before culling), decal create should never fail as it only gets called when there is a weapon colision detected, so there must be something screwed up with the actual generation code, but that isn't posable as I havn't done anything to it!
I'm trying this one more time then going to sleep
