hey roxaz if you wouldnt mind you could knowingly commit a crime and pm me your link, im a poor student and interested in ai game programming... i could eventually accept this crucial lapse with a heavy heart..

You don't need the book Frodenius. Come on AI is just common sense in my opinion. Besides there are millions of articles for you on gamedev.net about A*, etc etc.

Yes there are even A* libraries such as this one
http://www.grinninglizard.com/MicroPather/index.htm to help you along as well.
AI is really a bunch of decision making if statements.
For example if you want a monster that runs at your character and explodes your AI is something like this:
Code: Select all
if(monster->isAlive())
if(moster->canSeePlayer())
{
if(player->getPosition.X() < monster->getPosition.X())
monster->moveXNegative();
else
monster->moveXPositive();
if(player->getPosition.Z() < monster->getPosition.Z())
monster->moveZNegative();
else
monster->moveZPositive();
if(monster->getPosition.X() - player->getPosition.X() < 10 ||
monster->getPosition.X() - player->getPosition.X() > -10)
if(monster->getPosition.Z() - player->getPosition.Z() < 10 ||
monster->getPosition.Z() - player->getPosition.Z() > -10)
if(monster->getPosition.Y() - player->getPosition.Y() < 10 ||
monster->getPosition.Y() - player->getPosition.Y() > -10)
monster->explode();
}
Its simple, like writing out a thought process.

The word terrorist would fit well, instead of monster.

I would recommend you to leave it monster ...else somebody may come with idea of spreading war against terrorism to your code. You dont want to se Toronto be bombed by F15s and Tomahawks, do you?

sorry i'm indonesian
this code rotate each actor to face their closest target, but stil got some trouble, may be because i haven't read all about matrixes
Code: Select all
void runAi(actor* head){
float jarak,dX,dZ,sudutTarget,sudutSekarang;
core::vector3df pos1,pos2,rot;
int attack;
float tambahan;
bool attackAble =false ;
if(Live>0){
if((target==NULL)||(target->Live<1)){
pickTarget(head);
resetControl();
//printf("id : %d cari musuh %d\n",id,&target);
}else{
pos1 = node->getPosition();
pos2 = target->node->getPosition();
dX = pos2.X-pos1.X;
dZ = pos2.Z-pos1.Z;
if(pos2.Z>pos1.Z){
dZ *= -1;
dX *= -1;
tambahan = 180;
}else{
tambahan = 0;
}
jarak = sqrt(dX*dX+dZ*dZ);
rot = node->getRotation();
sudutSekarang = rot.Y;
sudutTarget = atan(dX/dZ);
sudutTarget = sudutTarget*180/3.14;
if(sudutSekarang+10 < sudutTarget+tambahan){
input->turn = 3;
attackAble=false;
}else if(sudutSekarang-10 > sudutTarget+tambahan){
input->turn = -3;
attackAble=false;
}else{
attackAble=true;
}
if(jarak>20){
input->accelerate=2;
}else if((jarak<=20)&&(jarak>10)){
input->accelerate = 1;
}else{
input->accelerate=0;
if(attackAble){
input->turn = 0;
if(target->Live>0){
input->speedAttack = true;
}else{
input->speedAttack = false;
}
}
}
}
}
}
i assume even if the ai to control the it self it throug a class thal i call the input class.
