Ball shaking problem

Help & Support
1

What do you think is the reason why the ball vibrates when I play on mobile in my game?

( It doesn’t work when you hit the obstacles in the game. I haven’t done them yet. Refresh the page to start over in the game.)

Could you elaborate on what you mean by the ball vibrating, or show a video? If I had to guess based on the last time you had a similar issue on a different project, your framerate is dropping because you have a lot of logic in your update loop.

I guess this is a camera issue, because I see the problem also on my laptop. Do you move your camera with a script? A link to the editor of your project would be nice.

var CameraController = pc.createScript('cameraController');

CameraController.attributes.add('Sphere',{
    type: 'entity'
    
});

CameraController.attributes.add('offset',{
   type: 'vec3' 
});

// initialize code called once per entity
CameraController.prototype.initialize = function() {
    this.offset = this.entity.getPosition().sub(this.Sphere.getPosition());
    
};

// update code called every frame
CameraController.prototype.update = function(dt) {
    
    this.entity.setPosition(this.Sphere.getPosition().add(this.offset));
    
};

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

Try to use postUpdate instead of update.

var CameraController = pc.createScript('cameraController');

CameraController.attributes.add('Sphere',{
    type: 'entity'
});

CameraController.attributes.add('offset',{
    type: 'vec3' 
});

// initialize code called once per entity
CameraController.prototype.initialize = function() {
    this.offset = this.entity.getPosition().sub(this.Sphere.getPosition());
};

// update code called every frame
CameraController.prototype.postUpdate = function(dt) {
    this.entity.setPosition(this.Sphere.getPosition().add(this.offset));
};
