Can't pass variables between 2 scripts
hi,
I have 2 scripts, a renderItem script assigned to 10 item gameobjects(locations) out of which only 1 will spawn(render) and a globalVariables script assigned to an empty game object in the scene to select which location will be spawned.
when I run the following scripts, nothing is generated in the scene. I found out that the problem is that renderItem.js for each item cannot see any variables from the globalVariabes script. Any ideas on what I am doing wrong?
I have used the same type of setup for OnMouseDown() functions in the past and it works, why does it not work with Start() or Update()?
Thanks in advance!
renderItem.js:
var KeyObj:GameObject;// model to be rendered
var keyPosition:int;//manually set when placed in scene(1,2,3...etc)
function Start()
{
var scriptt: globalVariables = GetComponent(globalVariables);
KeyObj.renderer.enabled=false;
if((script.keyPos[keyPosition]))
KeyObj.renderer.enabled=true;
}
globalVariables.js
static var keyPos:boolean[];//key spawn poing
keyPos= new boolean[10];//10 locations to choose from
function Awake(){
//following values will be randomly assigned later on
keyPos[3]=false;
keyPos[2]=true;//spawn at location 2
keyPos[1]=false;
keyPos[0]=false; }
You can see a long explanation on http://unitygems.com/. You can find how to access variables from other scripts and an explanation on static variables in the memory management section.
You can access static variables directly using the script name (class name, actually) directly like this:
...
if((globalVariables.keyPos[keyPosition]))
KeyObj.renderer.enabled=true;
...
NOTE: Your original code would work only if globalVariables.js were attached to the same object as renderItems.js.
Thanks for answering! I didn't know that. I tried it but still no luck though. Also, i noticed that I get a log error:"Object reference not set to an instance of an object" for the above if statement, any clues?
Thanks again!
Do you have anything in the $$anonymous$$eyObj slot of the Inspector or does it say None(GameObject)?
You usually get errors when trying to modify prefab properties by script - do it in the instantiated object ins$$anonymous$$d. You could instantiate the $$anonymous$$eyObj first, then modify the clone like this:
var kObj: GameObject = Instantiate($$anonymous$$eyObj, ...); // get a ref to the clone
if (globalVariables.keyPos[keyPosition])
kObj.renderer.enabled=true; // set the clone renderer
...
