Collision detection (bounding box)
Author
Hello,
I am currently writing a collision detection for my 3d game. Unfortunately, it does not work; Sometimes it does not recognize collisions. I think that the problem should be within the following lines (the y coordinates are ignored right now!). Any idea what went wrong? Thanks in advance!
bool GfxEngine::BoxesTouch(const BOUNDINGBOX* box1, const BOUNDINGBOX* box2)
{
bool bHaveTouched=false;
if(((box2->minx >= box1->minx) && (box2->minx <= box1->maxx) &&
(box2->minz >= box1->minz) && (box2->minz <= box1->maxz) &&
(true))
||
((box2->minx <= box1->minx) && (box2->maxx >= box1->minx) &&
(box2->minz <= box1->minz) && (box2->maxz >= box1->minz) &&
(true)))
bHaveTouched=true;
//Wert zurückgeben
return bHaveTouched;
}
I don''''t need any signature ;-)
You are better off checking if the boxes are *not* intersecting:
if(box1->maxx < box2->minx || box2->maxx < box1->minx)
return no_hit;
if(box1->maxz < box2->minz || box2->maxz < box1->minz)
return no_hit;
return hit;
if(box1->maxx < box2->minx || box2->maxx < box1->minx)
return no_hit;
if(box1->maxz < box2->minz || box2->maxz < box1->minz)
return no_hit;
return hit;
