Global parameter, Count int. how do i do that ?

Question

I guess for some of you a pretty basic thing, but i don't know how to do it.

i have Javascript A, and Javascript B.

within A i have a simple int parameter called countX this count registers a event, and counts ++ for each time the event happens.

in script B, i want to be able to "read" the current value in A. And for example, be able to make it -- (so it is also -- in A)

can anyone help me out ? thanx

In your B script put the following:

 var aScript : AScript;

 function Start() {
     aScript = gameObject.GetComponent.<AScript>(); // assuming both scripts are attached to the same GameObject
     if(!aScript)
        Debug.Log("Couldn't find ScriptA.");
 }

And then wherever you want to reference countX, just put: aScript.countX. Hopefully this helps.

Adding on from what @jaised said, if your scripts are attached to different objects, add

var objWithScriptA : GameObject;

to start of script. Add gameobject with script A attached in inspector, and then ins$$anonymous$$d of aScript = gameObject.GetComponent.<AScript>(); make it

aScript = objWithScriptA.GetComponent.<AScript>();

There you go. You're all set!

It's a bit faster if you do GetComponent(AScript) rather than GetComponent.<AScript>(), plus it's easier to type.

And even faster and easier is to drag&drop the script itself ;)

Ins$$anonymous$$d of

 var objWithScriptA : GameObject;

just use

 var aScript : AScript;

and drag the other gameobject onto that variable. Unity will assign the component reference of the right type if there is one. There's no need for GetComponent then.
