Collision of objects with world camera

Tried to collide two objects, works great until i put the camera with world tracking.

idea was to attach a object to the camera so as it moves it could dodge the object if needed.

but I feel this is messing up with the 3d space due to the camera been world

// -----JS CODE-----

// @input SceneObject objectA

// @input float collideDistance = 0.25

// @input SceneObject objectB




var objA = script.objectA.getTransform().getWorldPosition();

var objB = script.objectB.getTransform().getWorldPosition();




var distance = Math.abs( objA.distance(objB));




if( distance <= script.collideDistance ) {

print( "COLLIDE!" );

script.objectA.enabled = false;




}

else

{

}

Hey Patrick! I tested your script and it works fine for me when world tracking was enabled. Here are a few things though that I had to do to make it work:
- To create an empty world tracking enabled scene, I just created a new Animated Object template and then deleted the WorldObjectController
- I created two box objects. Then, I added a manipulate component and touch component to both. And then, checked Drag on both manipulate components. This gives me two boxes that I can drag around the scene (and move them close to each other in real time)
- At first I thought it wasn't working but then I realized I had to have the script run on "Frame Updated". This way your logic is checking every frame and not just the first frame
- Finally, the 0.25 was too small to get a collide. I had to bump it to about 25.0 to have it easily collide without having to be super precise
Hope something here points you in the right direction!
