AI enemy vechicle problem
I want to know about script for control a tank. I can make it look at and follow player but I have some problem. the enemy tank don't see player it will move to straight and when it move to something such as a wall or bigstone it can't turn away from that object so the enemy tank will fools because it can't move to anywhere.
That's not an easy question - avoiding obstacles is a complex task. In this case, maybe you could use the following algorithm: each Update, cast a short ray forward; if nothing is hit, move the tank; if it hits something, enter a state where the tank will rotate a fixed angle (15 degrees, for instance) then return to idle state, where it will again verify obstacles ahead - something like this:
enum State {Idle, Chase, Attack, TurnLeft, TurnRight}; var state: State = State.Idle; var turnSpeed: float = 60; // 60 degrees per second var length: float = 8; // "see" 8 units ahead private var turnAngle: float = 0;
function Update(){ switch (state){ case State.Chase: // chase the player case State.Idle: if (!Physics.Raycast(transform.position, transform.forward, length)){ // move the tank forward if no obstacles ahead } else { // if some obstacle in range, enter turn right state: state = State.TurnRight; turnAngle = 15; } break; case State.TurnRight: // stay in turn mode until turnAngle ends: var dAngle = turnSpeed * Time.deltaTime; transform.Rotate(0, dAngle, 0); turnAngle -= dAngle; // when turnAngle ended, return to idle state: if (turnAngle
