[SOLVED] Anim script interface troubles

Help & Support
,
1

Hello, all.
I have a script that when when it gets a fire, it plays and animation by setting a boolean to true, and stops it on another fire by setting the boolean to false. Thats what its supposed to do.

var IcelitRecorderMask = pc.createScript('icelitRecorderMask');
IcelitRecorderMask.attributes.add('player',{type:'entity'});

// initialize code called once per entity
IcelitRecorderMask.prototype.initialize = function() {
    ///Events 
const p1moveTrue = function(){
this.entity.anim.setBoolean('P1Move', true);
};
const p1moveFalse = function(){
this.entity.anim.setBoolean('P1Move', false);
};


//Listen + destroy Events
this.app.on('Anim:P1Move-True',p1moveTrue);

this.on('destroy', function() {
        this.app.off('Anim:P1Move-True', p1moveTrue);
    });

this.app.on('Anim:P1Move-False', p1moveFalse);

this.on('destroy', function() {
        this.app.off('Anim:P1Move-False', p1moveFalse);
    });

};


// update code called every frame
IcelitRecorderMask.prototype.update = function(dt) {
this.entity.lookAt(this.player.getPosition().x,this.player.getPosition().y,this.player.getPosition().z);
};

// uncomment the swap method to enable hot-reloading for this script
// update the method body to copy state from the old instance
// IcelitRecorderMask.prototype.swap = function(old) { };

The fires are firing, but there error is on line 8. Here is the error I get: [icelitRecorderMask.js?id=204057013&branchId=eac69c03-02df-4539-ad25-d27acd4e91a1:8]: Cannot read properties of undefined (reading ‘anim’)

Hi @Codeknight999!

In your events this is undefined or something like that. I can’t explain why because I don’t understand everthing myself, but you can solve it like the way below.

//Events 
const p1moveTrue = function(){
    this.entity.anim.setBoolean('P1Move', true);
}.bind(this);
const p1moveFalse = function(){
    this.entity.anim.setBoolean('P1Move', false);
}.bind(this);

That fixed it, thanks!
