Sensors and Triggers

Ok, I've been spending way too much time on this and im reaching out for some help on this issue.

I'm using Torque2D 3.0, and I'm developing an Android game right this second.

I'm trying to setup a standard Trigger (or Sensor) that has the behaviour of when an object (Sprite ScenObject with a PolygonBoxCollisionShape) enters the Trigger object's space (or a ShapeVector SceneObject with a Sensor collision flag):
1. Physics do NOT happen
2. Callbacks are triggered on collision


The problem I have here is one of two scenarios:

1. With %myTrigger.Active set to true AND/OR CollisionShapeIsSensor set to false (or both properties ignored entirely), my Sprite SceneObject is being "pushed away" by the Trigger SceneObject as if it were a solid thing, BUT the Trigger or standard Collision callbacks (depending on the type of object) get triggered, and therefore allows my game to continue normally, but looks extremely awkward and horrible
(Demonstration of this effect: https://www.youtube.com/watch?v=W68IO6szjJw [placeholder graphics])
or
2. With %myTrigger.Active set to false AND/OR CollisionShapeIsSensor set to true, my Sprite and Trigger SceneObjects no longer push eachother away, but NONE of the collision callbacks ever get called. Therefore the game just ends immediately.


The gameplay is super simple at play: stay within the Trigger zone until a certain moment, as you enter or leave the trigger/sensor zone a global flag is set whether your safe or not. when that moment arrives to evaluate that flag and determins that you are safe, the Trigger/Sensor object and some visual elements are removed and respawned somewhere else, else end the game.



Everything I try, I get one of those two results. Either the game plays correctly (can enter the trigger zone with no resistance) but collisions never get triggered, OR the game has physics enabled and works against each-other but the collisions "kinda" work

Not sure how to proceed

function spawnBird(%x, %y)
{
	%sprBird = new Sprite(BirdPawn);
    %sprBird.Position = %x SPC %y;
    //%sprBird.setBodyType( static );
    %sprBird.Image = "Bird:Bird";
    %sprBird.Size = "7 8";
    %sprBird.createPolygonBoxCollisionShape();

    %sprBird.SceneGroup = 10;
    
    myScene.add(%sprBird);

    $birdObj = %sprBird;
}

function spawnWindow()
{
	$SceneObjects[0] = null;
	$SceneObjects[1] = null;

	$windowActive = true;

// Purely aesthetic, a clear "window" is drawn, to be able to "fly through"
	%window = new ShapeVector(Window);
	%randomX = getRandom(-30, 30);
	%randomY = getRandom(-30, 30);
	%window.setPosition(%randomX SPC %randomY);
	%window.setSize(0.1);
	%window.setLineColor("0.5 1 1 1");
	%window.setFillColor("0.5 1 1 0.5");
	%window.setFillMode(true);
	%window.setPolyPrimitive(4);
	%window.setSceneGroup(4);

	$SceneObjects[0] = %window;

	myScene.add(%window);

// This should act as the implicit shape that the window ends up being at the time of the 
// evaluation (size 20)
	%trigger = new Trigger(WindowTrigger);
	%trigger.setEnterCallback(true);
	%trigger.setLeaveCallback(true);
	%trigger.setPosition(%randomX SPC %randomY);
	%trigger.setSize(20);
	%index2 = %trigger.createPolygonBoxCollisionShape();
	%trigger.setCollisionShapeDensity(%index2, 0);
	%trigger.setCollisionShapeFriction(%index2, 0);
	

	$SceneObjects[1] = %trigger;

	myScene.add(%trigger);
}


/////////////////
////  This works only when the Trigger acts as a physics object. 
////  That should not be...
/////////////////
function WindowTrigger::onEnter(%this, %object)
{
	echo("================= OH EM GEE IT WORKS");
	$inWindow = true;
}

function WindowTrigger::onLeave(%this, %object)
{
	echo("================= HEY NO GET BACK HERE!");
	$inWindow = false;
}


function Window::update(%this) 
{
	//echo("IN Window:" SPC $inWindow);
	if(%this.getSize() < 20) {

		%this.setSize(%this.getSize() + $speed);

	} else {
		// do evaluation check
		if($inWindow) {
			$windowActive = false;
			$inWindow = false;
			$score++;
			echo("Score:" SPC $score);

			if($score <= 3) {
				$speed = 0.2;
			} else if($score <= 6) {
				$speed = 0.4;
			} else if($score <= 8) {
				$speed = 0.7;
			} else if($score <= 10) {
				$speed = 1.0;
			} else if($score > 10) {
				$speed = 2.0;
			}

			$SceneObjects0.safedelete();
			$SceneObjects1.safedelete();
		} else {
			$gameState = "death";
		}
	}
