Question by rdanielsson · May 24, 2012 at 02:58 PM · errorreferencingexpression

Expression cannot be assigned to, doing it wrong, but how?

I have two scripts in different .js files and i want to refer to one through the other, i have watched the GUI tutorial by tornadotwins, and i am trying that method to get a guitexture to show when my player collides with a pickup.

Here is the script for PointGet which i want to make the gui appear with

 #pragma strict

static private var onPoint : boolean = false;

function FixedUpdate () {

if(onPoint == true){

guiTexture.color.a = 255;

yield WaitForSeconds (1);

onPoint = false;

 }

}

That script is triggered from a script in my player file:

 if(shipTrigCollision.gameObject.tag == "TrianglePickup"){
 
 PointGet = true; // Sets the statement as true in our pointget script
 
 audio.PlayOneShot(trianglePickupCollideSound);
 
  Destroy(shipTrigCollision.gameObject); // Destroys the game object
 }


That script is triggered from a FixedUpdate function in the player file, i have no idea what i am doing wrong. I would be grateful if someone could point at the errors :)

It looks to me like you aren't accessing the right property in the second script.

You should perhaps make the onPoint definition in the first section be this:

 static public var onPoint : boolean = false;

Then in the second script in place of:

 PointGet = true;

do

 PointGet.onPoint = true;

Another point is that you usually can't use FixedUpdate as coroutine. Also fixedUpdate should only be used for Physic movement related stuff. Usually you use Update for most things.
