SimpleRaycast

SimpleRaycast

This bypasses the interactable system 
let me know what you think 
remember that you need to set up the ray start and end 
you can create 2 scene objects and put them under the main camera 

1. at 0,0,0
2. at 0,0,-100 (forward) 
then assign a 3rd object that is the one that is instantiated on the hitPoint of the raycast 
remember that the geometry receiving the raycast needs to have a collider and a physics body 
if you want the receiver to not be dynamic uncheck the dynamic option so it won' react to physics 
remember that if you want to impact any world surface use the worldQueryModule in the AssetLibrary 
this below is a simplify approach without interactors/worldQueryModule 
// Given an object with a BodyComponent
// If the object intersects with the ray described
// by rayStart and rayEnd, print a message.
@component
export class SimpleRaycast extends BaseScriptComponent {
    @input rayStart: SceneObject;
    @input rayEnd: SceneObject;
    @input trail: SceneObject;

    onAwake() {
        // Check if trail is defined
        print("Trail object defined: " + (this.trail !== undefined));
        
        this.createEvent("OnStartEvent").bind(() => {
            this.onStart();
        });

        this.createEvent("UpdateEvent").bind(() => {
            this.updateObjectMovement();
        });
    }

    onStart() {
        // Check if trail is defined at start
        print("Trail object at start: " + (this.trail !== undefined));
        if (this.trail) {
            print("Trail object name: " + this.trail.name);

        var globalProbe = Physics.createGlobalProbe();

        print("Trail object before raycast: " + (this.trail !== undefined));
