Im having a problem where isPointInside and intersectsWithBox functions keeps returning true (or what the functions are returning) eventhough the objects arent colliding.
The documentation states that the function "returns" if there is a collision, so Im assuming the code below should be correct to
do a proper BoxvsBox/Point collision check.
var Box1 = scene.getSceneNodeFromName("Box1");
var Box2 = scene.getSceneNodeFromName("Box2");
if(!Box1 || !Box2)
return;
Box1.updateAbsolutePosition();
Box2.updateAbsolutePosition();
var BBox1 = Box1.getBoundingBox();
var BBox2 = Box2.getBoundingBox();
var Center = BBox1.getCenter();
if(BBox2.isPointInside(Center) != null)
alert('isPointInside collision');
if(BBox1.intersectsWithBox(BBox2) != null)
alert('intersectsWithBox collision');
Am I doing this wrong, or isnt the box3d collision fully functional?

You are testing the local bounding boxes, that's why they collide. What you want is the transformed bounding boxes. Instead of getBoundingBox(), use getTransformedBoundingBox().
