Hello, i have an error in my raycast script but i don’t see it can you help me?

onMouseDown: function (e) {
    // scale coords to be in canvas resolution
    var device = app.graphicsDevice;
    var _x = e.screenX;
    var camera = app.systems.camera.cameras[0].entity;
    this.rayStart.copy(camera.getPosition());
    camera.camera.screenToWorld(e.x, e.y, 1, this.rayEnd);
    this.rayEnd.sub(this.rayStart).normalize().scale(RAY_LENGTH).add(this.rayStart);
    app.systems.rigidbody.raycastFirst(this.rayStart, this.rayEnd, this.onRayHit.bind(this));
},

What’s the error? Debugging code by inspection is never easy. It’s always good to link to a scene showing the problem, copy/paste or screenshot errors, and so on.

When you say error do you mean an error message in the Code Editor? If so we fixed a bunch of them today…

i have another error that i can’t understand the origin in this project

Error loading scripts. Open the browser console for details.

One error I see if that you’re doing this in enemy.js:

    this.entity.collision.on('collisionstart', this.onCollisionStart, this);

But onCollisionStart is not defined in the script. Passing ‘undefined’ as the callback parameter will cause exceptions to be thrown internally in the engine. It’s the same story in prey.js.
