Hey guys, I have this script for movement, and before you comment on the functionallity, you should know
that this script performs the kind of movement that I actually need it to.
My problem is, that I’m casting a ray form the player, and when it hits a wall, a boolean goes ‘true’. However, when the user is then looking away from the wall, that boolean should go back to false, and it doesn’t.
Can anybody tell me what the problem is, and how to fix it?
This is the script:
(the problem is in the *Raycast’ section of the script)
/*
Movement Script for strict movement,
1 unit at a time
*/
// Variables
public var playerCharacter : GameObject;
public var distance : float = 2;
private var playerZ = playerCharacter.transform.position.z;
var lookingAtWall : boolean = false;
// Move functions
// Forward movement
function moveForward()
{
playerCharacter.transform.Translate(0, 0, 1);
}
// Backwards movement
function moveBackwards()
{
playerCharacter.transform.Translate(0, 0, -1);
}
// Rotate left
function rotateLeft()
{
playerCharacter.transform.Rotate(0, -90, 0);
}
//Rotate right
function rotateRight()
{
playerCharacter.transform.Rotate(0, 90, 0);
}
// Update function (runs once every frame)
function Update()
{
/* RAYCAST */
var dir = transform.forward;
var hit : RaycastHit;
Debug.DrawRay(transform.position, dir * distance, Color.blue);
if( Physics.Raycast( transform.position, dir, hit, distance ) ){
if( hit.collider.gameObject.tag == "Wall" ){
print("You are looking at a wall!");
lookingAtWall = true;
}
else if( hit.collider == "None" ){
lookingAtWall = false;
}
}
// If player presses 'W' and z-position is less than 8; move forward
if(Input.GetKeyDown(KeyCode.W) playerCharacter.transform.position.z <= 8 lookingAtWall == false){
moveForward();
}
// If player presses 'S' and z-position is more than 1; move backwards
if(Input.GetKeyDown(KeyCode.S) playerCharacter.transform.position.z > 1){
moveBackwards();
}
// If player presses 'A'; rotate left
if(Input.GetKeyDown(KeyCode.A)){
rotateLeft();
}
// If player presses 'D'; rotate right
if(Input.GetKeyDown(KeyCode.D)){
rotateRight();
}
}
