I am working on a game where I need artificial intelligence for enemy characters to, A: Stay close enough to the ground, B: Generate Patrol Lines Between Several Waypoints, C: Be Able to Generate Patrol Lines while chasing the player, that avoids obstacles. I know about all of the packages and stuff, but I just need some insight on these concepts, not someone to write scripts for me. I'm an ok programmer, but not a "newbie" despite my name. The reason I want to create my own is so that I have full control over the AI and this is a learning project, so getting an already made set of scripts which I cannot really customize and won't learn from, won't help. If I get help with the above listed concepts, I'll already understand how to implement new things.
Here is my current script (some of it is recycled from my older scripts):
var rotationSpeed = 5;
var moveSpeed = 5;
var maxHealth = 100.0;
var curHealth = 100.0;
var healthBarLength : float;
var waypoint : Transform[];
var currentWaypoint : int;
var target : Transform;
var groundDistance : float;
var isGrouned : boolean;
function Start(){
healthBarLength = Screen.width / 4;
distToGround = collider.bounds.extents.y;
}
function Update(){
var targetPos = target.position;
targetPos.y = transform.position.y;
var targetRotation = Quaternion.LookRotation(targetPos - transform.position);
var i = Time.deltaTime * rotationSpeed;
var m = Time.deltaTime * moveSpeed;
if(Physics.Raycast(transform.position, -Vector3.up, groundDistance)){
isGrounded = true;
}else
isGrounded = false;
if(isGrounded){
transform.rotation = Quaternion.Slerp( transform.rotation, targetRotation, i);
transform.position = Vector3.MoveTowards(transform.position, target.position, m);
}
}
function AdjustCurrentHealth() {
if(curHealth < 0)
curHealth = 0;
if(curHealth > maxHealth)
curHealth = maxHealth;
if(maxHealth < 1)
maxHealth = 1;
healthBarLength = (Screen.width / 4) * (curHealth / maxHealth);
}
function OnGUI() {
GUI.Box(Rect(1050, 10, healthBarLength, 20), curHealth + "/" + maxHealth);
}
function OnDrawGizmos () {
// Draws a 5 meter long red line in front of the object
Gizmos.color = Color.red;
var direction : Vector3 = transform.TransformDirection (Vector3.forward) * 10;
Gizmos.DrawRay (transform.position, direction);
var direction2 : Vector3 = transform.TransformDirection (-Vector3.up) * groundDistance;
Gizmos.DrawRay (transform.position, direction2);
}
