[SOLVED] How To Change A Variable From Another Script

I want to make a script to attach to a trigger area that returns the grounded variable on my player to false. Seems simple enough, but one problem. I don’t know how to change the variable from another script. I’ve tried a couple of ways, but I just can’t seem to change a variable from an external script. My question here is, what is the proper way to change a variable from an external script?

Hi @DevPlex01,

The most straightforward way is to get a reference to the entity holding that other script instance and follow this pattern:

  • myScriptName, you can find this by clicking in your script asset after you parse it. This is the script type name as registered when parsed.
  • myPropertyName, this should be the name of the property you are trying to update in your script. Note you can’t access local variables, only properties like this:
this.playerName = 'aName'; 

So does this mean I can access attributes but not normal variables?

What do you mean with “normal variables”?

You can access anything that is a property of the this object which includes attributes.

Oh ok, I think i get it now.

Also you can use events if you only wants to set the state of other variable and not to get it.

Indeed events are quite powerful and it’s my preferred way of communicating between scripts. Here is a simple example:

ScriptA.prototype.initialize = function(){
   this.myProperty = 'nameA';

   this.app.on('change:name', function(newName){
      this.myProperty = newName;
   }, this);

ScriptB.prototype.initialize = function(){
   this.app.fire('change:name', 'nameB');

Events good for interface alternative, direct variable most preferable. Many events many ruined perfomance ((
