About call a function in a script on another entity

Help & Support
#1

Hi guys,

I am a novice, im trying call a function in a script on another entity in the following way：

otherEntity.script.scriptName.myFunction()

i got this error:

Uncaught TypeError: Cannot read property ‘script’ of undefined

How do I call a function correctly in a script on another Entity?

help me,plz…

It’s saying that otherEntity is undefined. Your line of thinking is correct on how to call the function on another script instance though.

#3

but i have definded the entity.

The error says otherwise. Can you post a link to the project please?

thx for your replay.
here is code:

the ui.js:

var Ui = pc.createScript('ui');

Ui.attributes.add('css', {type: 'asset', assetType:'css', title: 'CSS Asset'});
Ui.attributes.add('html', {type: 'asset', assetType:'html', title: 'HTML Asset'});
Ui.attributes.add('atenza', {type: 'entity'});

Ui.prototype.initialize = function () {

    var style = document.createElement('style');

    document.head.appendChild(style);
    style.innerHTML = this.css.resource || '';
    
    this.div = document.createElement('div');
    this.div.classList.add('container');
    this.div.innerHTML = this.html.resource || '';
    
    document.body.appendChild(this.div);
    
    this.bindEvents();
};

Ui.prototype.bindEvents = function() {

    var button = this.div.querySelector('.button');

    if (button) {
        button.addEventListener('click', function() {
  
            console.log('button clicked');
            this.atenza.script.tweenMaterial.reset();

        }, false);
    }

};

the “atenza” is an entity reference, the"tweenMaterial" is a script on the atenza entity, reset() is a function in the tweenMaterial script.

    if (button) {
        button.addEventListener('click', function() {
  
            console.log('button clicked');
            this.atenza.script.tweenMaterial.reset();

        }, false);
    }

As the callback is in a lambda function, the this reference isn’t pointing to the same this outside the function.

The way to get around this is to declare a new variable pointing to this and use that instead in the callback so the lambda can capture the variable.

    if (button) {
        var self = this;
        button.addEventListener('click', function() {
  
            console.log('button clicked');
            self.atenza.script.tweenMaterial.reset();

        }, false);
    }
