[SOLVED] Stop a sprite clip?

Help & Support
1

Here is the code (I am applying the script to the current entity (this.entity)):

var AnimationHandler = pc.createScript('animationHandler');

// initialize code called once per entity
AnimationHandler.prototype.initialize = function() {
    
};

// update code called every frame
AnimationHandler.prototype.update = function(dt) {
    
    if (this.app.keyboard.isPressed(pc.KEY_LEFT)) {
    this.entity.sprite.play('moving');
    }
    
    if (this.app.keyboard.isPressed(pc.KEY_RIGHT)) {
    this.entity.sprite.play('moving');
    }
    
    if (this.app.keyboard.isPressed(pc.KEY_DOWN)) {
    this.entity.sprite.play('moving');
    }
    
    if (this.app.keyboard.isPressed(pc.KEY_UP)) {
    this.entity.sprite.play('moving');
    }
    
    //stop the moving sprite clip, switch to idle
    
    
    if (this.app.keyboard.wasPressed(pc.KEY_RIGHT)) {
    this.entity.sprite.stop('moving');
    }
    
    
    //another method for the code above
    
    AnimationHandler.prototype.onKeyUp = function (event) {
    // Check event.key to detect which key has been pressed
    if (event.key === pc.KEY_LEFT) {
        this.entity.sprite.stop('moving');
        this.entity.sprite.play('idle');
    }
    
    };
    
    AnimationHandler.prototype.onKeyUp = function (event) {
    // Check event.key to detect which key has been pressed
    if (event.key === pc.KEY_RIGHT) {
        this.entity.sprite.stop('moving');
        this.entity.sprite.play('idle');
    }
    
    };
    
    AnimationHandler.prototype.onKeyUp = function (event) {
    // Check event.key to detect which key has been pressed
    if (event.key === pc.KEY_UP) {
        this.entity.sprite.stop('moving');
        this.entity.sprite.play('idle');
    }
    
    };
    
    AnimationHandler.prototype.onKeyUp = function (event) {
    // Check event.key to detect which key has been pressed
    if (event.key === pc.KEY_DOWN) {
        this.entity.sprite.stop('moving');
        this.entity.sprite.play('idle');
    }
    
    };

};

// swap method called for script hot-reloading
// inherit your script state here
// AnimationHandler.prototype.swap = function(old) { };

// to learn more about script anatomy, please read:
// http://developer.playcanvas.com/en/user-manual/scripting/

In the first section, I have code that detects when the sprite is moving and plays the moving sprite clip. I am trying to find a way (in the second half) to stop the moving animation and play the idle animation, but the moving clip just won’t stop.

I only have the first method of ‘trying’ to stop the animation applied to pc.key right, because I was testing it on that key. It does not work though

Hi @CRAYPHiSHQUESTIONS,

You will want to take a look at your if() statements. Since they are all in a row, they will all execute in the order that they are in if the conditions are true. For example, If press down and right at the same time, Playcanvas will begin playing the requested clip twice.

You will want to sort them something like this:

var AnimationHandler = pc.createScript('animationHandler');

// initialize code called once per entity
AnimationHandler.prototype.initialize = function() {
    
};

// update code called every frame
AnimationHandler.prototype.update = function(dt) {
    
    if (this.app.keyboard.isPressed(pc.KEY_LEFT)) {
    this.entity.sprite.play('moving');
    }
    
    else if (this.app.keyboard.isPressed(pc.KEY_RIGHT)) {
    this.entity.sprite.play('moving');
    }
    
    else if (this.app.keyboard.isPressed(pc.KEY_DOWN)) {
    this.entity.sprite.play('moving');
    }
    
    else if (this.app.keyboard.isPressed(pc.KEY_UP)) {
    this.entity.sprite.play('moving');
    }
    
    else if(this.app.keyboard.wasReleased(pc.KEY_LEFT)) {
        this.entity.sprite.play('idle');
    }
    
    else if(this.app.keyboard.wasReleased(pc.KEY_RIGHT)) {
        this.entity.sprite.play('idle');
    }

    else if(this.app.keyboard.wasReleased(pc.KEY_UP)) {
        this.entity.sprite.play('idle');
    }

    else if(this.app.keyboard.wasReleased(pc.KEY_DOWN)) {
        this.entity.sprite.play('idle');
    }
}

The example above is a really messy way of achieving your result, but I think for a beginning project it is more important to understand what your scripts are doing and why.

I hope this is helpful!
