Hi, i have DP and DAI my map is a terrain, i created a character controller and a little of tweaking and made myself a player, now i added some entities added this for the entities:

+ Code Snippet

void crtDeclareForestCyclop(int objID, int crtHealth, int crtForce, int pathID)
{
 AIAddEnemy(objID);
	if(pathID!=0){
	AIEntityAssignPatrolPath(objID,pathID);
	}
	AISetEntityAggressive(objID);
    AISetEntityAttackDistance(objID, 0.2f);

}

but my entities doesn't respect the terrain.
I`ve also added this

+ Code Snippet

dbLoadObject("models/map1.x",4);
	AIStartNewObstacle();
	AIAddObstacleFromLevel(4,0,0,2,10,10);
	AIEndNewObstacle(0,0);
AICompleteObstacles();

but still the same problem.

I`m using DP for physics in the game but how do i apply the physics to the enemy entities that are using DAI ?

Try manipulating the movement of the characters via the ground height of a matrix overlaying your landscape?

i also have dark ai, but have yet to actually use it...

reading through the docs tho, it seems as tho what you need to do is use dark ai in manual mode, instead of automatic.

like i said tho, i could be wrong

as for the physics, there is also a discussion toward the end of the chm that talks about the complexities of using dark ai with dark physics. i think it roughly translates to keep physics off characters until removed from ai.

So you're using DP for your collision and along with the Dark AI? Things get a little more complicated when you try to use them together unless you know what you're doing. For using Dark AI and Dark Physics together fluidly, I recommend checking out this topic: http://forum.thegamecreators.com/?m=forum_view&t=109308&b=30

Hope that helped at least a little!

Currently working on - Enemy AI using Dark A.I. I probably should've looked at the reviews in the Dark Physics and Dark A.I. forum first.

Almost did it...i mean it should work now but i`m having a problem, using the code from that post gets me into another problem, i don't know how to use the Y axis.

i`m using this code

+ Code Snippet

before main loop
void crtDeclareForestCyclop(int objID, int crtHealth, int crtForce, int pathID, int posx, int posz)
{
 dbPhyMakeRigidBodyDynamicCapsule(objID);
 AIAddEnemy(objID,0);
 AISetEntityPosition(objID,posx,posz);
 

	if(pathID!=0){
	AIEntityAssignPatrolPath(objID,pathID);
	}
 AIEntityLookAround(objID,0,180);
 AISetEntityAggressive(objID);
 AISetEntityAttackDistance(objID, 0.2f);
	
}
into the main loop:
void crtActForestCyclop(int objID)
{
dbPhySetRigidBodyKinematicPosition(objID,AIGetEntityX(objID),dbObjectPositionY(objID),AIGetEntityZ(objID));
}

but when the game starts the entity just keeps rising, any Y number set does the same, if i set it lower he goes down, bigger, goes up and not stopping.

How do i solve this one ?

Thanks in advance!

what happens if you set y to zero each loop when nothing is going on.

he just disappears off-map....anyway, my terrain has slopes and i want the entity to move according to the terrain and setting it to 0 will just stay on that point of axis or in this case it doesn't even stay there...theortical should stay on that point but it didn't.
