var centerScreenX = (this.app.graphicsDevice.width / 2) ;
var centerScreenY = (this.app.graphicsDevice.height / 2) ;

// get start and end point
var start = this.camera.camera.screenToWorld(centerScreenX, centerScreenY, this.camera.camera.nearClip);
var end = this.camera.camera.screenToWorld(centerScreenX, centerScreenY, this.camera.camera.farClip);
    
// raycast between the two points and return the closest hit result
var result = this.app.systems.rigidbody.raycastFirst(start, end);
