[edit] If i take out the check for buildings from the weapon firing code, it seems to work just fine. So something is messed up with that building stuff [/edit]
I don't know why, but in 0.12, my zombies would work just fine. They would
cast two rays one angled outt o the left an done angled out to the right. If anything intersected with one of those (buildings), they'd turn the other way. But now they are all just turning all the time! Right in the middle of huge open areas with no problems!
Something is seriously screwy. Also my raycasting from my camera to detect if a zombie is hit by a bullet is very wacky. Every now and then it will work and the zombie will die, but most often it just does absolutely nothing.
It all worked perfectly when compiled with 0.12.
Also please do not suggest using collision animators, etc. I have over 300 zombie entities. Irrlicht chokes if I do built-in collision testing on all those.
Heres a code snippet of my AI collision testing:
Code: Select all
bool AICanMove(int i)
{
float lookAhead=0.0f;
matrix4 mat=entityArray[i].node->getAbsoluteTransformation();
vector3df dirVec = vector3df(mat.M[8],mat.M[9],mat.M[10]);
vector3df movVecLeft;
vector3df movVecRight;
vector3df nodePos = entityArray[i].node->getPosition();
line3d<f32> rayRight;
line3d<f32> rayLeft;
//get max lookahead distance in case of low fps
if (aiColLookAhead < 0)
lookAhead = min(-1*ai::GetTimedAmount(currentTimeMs-lastTimeMs, entityArray[i].movSpeed), aiColLookAhead);
else
lookAhead = max(ai::GetTimedAmount(currentTimeMs-lastTimeMs, entityArray[i].movSpeed), aiColLookAhead);
//right lookahead ray
movVecRight = dirVec;
movVecRight.normalize();
movVecRight.rotateXZBy(aiColLookAngle, vector3df(0,0,0));
movVecRight *= lookAhead;
movVecRight += nodePos;
rayRight = line3d<f32>(nodePos,movVecRight);
//left lookahead ray
movVecLeft = dirVec;
movVecLeft.normalize();
movVecLeft.rotateXZBy(-1*aiColLookAngle, vector3df(0,0,0));
movVecLeft *= lookAhead;
movVecLeft += nodePos;
rayLeft = line3d<f32>(nodePos,movVecLeft);
//CHECK FOR BUILDINGS IN THE WAY
for (int j=0; j<levelSize; j++)
if (buildingArray[j])
{
//if (ai::GetDistance(buildingArray[j],entityArray[i].node) < maxSize)
//{
//if this one hits rotate right
if (buildingArray[j]->getTransformedBoundingBox().intersectsWithLine( rayRight ))
{
entityArray[i].node->setRotation(vector3df(0, entityArray[i].node->getRotation().Y + ai::GetTimedAmount(currentTimeMs-lastTimeMs, entityArray[i].rotSpeed*2), 0));
return false;
}
else
{
//if this hits go left
if (buildingArray[j]->getTransformedBoundingBox().intersectsWithLine( rayLeft ))
{
entityArray[i].node->setRotation(vector3df(0, entityArray[i].node->getRotation().Y - ai::GetTimedAmount(currentTimeMs-lastTimeMs, entityArray[i].rotSpeed*2), 0));
return false;
}
}
//}
