Question by deenooo · Oct 22, 2013 at 01:39 PM · movementtransformobjecttranslate

Moving an object

I made a script to move an object in the X axis. I got it to move to the right but can't get it to move in the opposite direction once it gets ti a certain position in game. Here is the script I made.

pragma strict

var speed : float = 4.0;

function Update () {

 transform.Translate(Vector3(speed,0,0) * Time.deltaTime);
 
 if(transform.position.x == -36){
 transform.Translate(Vector3(speed,0,0) * Time.deltaTime);
 }
 
 else if(transform.position.x == -25){
 transform.Translate(Vector3(speed,0,0) * Time.deltaTime);
 }

}

Any help would be grateful.

It would be practically impossible for the x value to be exactly -25 or -36. Use >= and

Store the speed in a separate variable, change the value of that variable based on the results of the conditionals.

 pragma strict
 
 public var speed : float = 4.0;
 
 private var currSpeed : float;
 
 function Start() 
 {
     currSpeed = speed;
 }
 
 function Update() 
 {
     if ( transform.position.x >= -25 )
     {
         currSpeed = -speed;
     }
     else if ( transform.position.x <= -36 )
     {
         currSpeed = speed;
     }
     
     transform.Translate( Vector3(currSpeed,0,0) * Time.deltaTime );
 }
