How to anticipate the Vector3.forward of the enemy?

Questions & Answers

Hi,

i would like my character to anticipate the direction of the enemy, in order to catch him. But my character looks too slow, and rotate just after the enemy passes him. So i would like the character to anticipate the next step of the enemy, with Vector.forward * 5 (in this example), but he does not seem to understand what i am trying to do, the z axis does not rotate fast enough so that the character can catch the enemy. Would you know why?

Here is the code :

//rotate the character every frame
if(enemyFound == true){
		//enemy to follow
		var newTransform : Vector3 = enemyToFollow.transform.position;
		newTransform += newTransform.forward*5*Time.deltaTime; //anticipate a bit, does not work
		directionToClosestEnemy = newTransform - transform.position;
		tempRot = Quaternion.Slerp(transform.rotation,Quaternion.LookRotation(directionToClosestEnemy),2*Time.deltaTime);
	}
	

//make him move
if(enemyFound == true){
		targetVelocity = enemyToFollow.transform.position - transform.position;
		targetVelocity = targetVelocity.normalized; // Is now speed 1, going correct way
		targetVelocity = targetVelocity * MOVE_SPEED;
		var velocityChange = (targetVelocity - velocity);
		velocityChange.y = 0;
		rigidbody.AddForce(velocityChange, ForceMode.Force);
	}

Thanks

Edit: do you mean like this ?

var newTransform : Vector3 = enemyToFollow.transform.position;
		newTransform += enemyToFollow.transform.forward * 100 * Time.deltaTime;
		directionToClosestEnemy = newTransform - transform.position;
		tempRot = Quaternion.Slerp(transform.rotation,Quaternion.LookRotation(directionToClosestEnemy),2*Time.deltaTime);

The reason why it doesn’t work is that you don’t add the enemy’s forward vector, but the Z-component of its position. You need to replace ‘newTransform.forward’ with ‘enemyToFollow.transform.forward’.
