Hi!
I have a question about collision between two meshes.
In the Playground below, I created two boxes. The box1 has a Behavior of being able to be moved with the mouse/pointer in z-axis and the box2 is fixed.
What I want to do is that box1 stop moving if it collides with box2, not being able to penetrate box2 or passing thorugh the other side.
The Playground: https://playground.babylonjs.com/#3F9X7S#1
What is the best / easiest way to do this?
I tried puttin a if for checking the position of box1 and returning it at a point before the box2, but when de user drags the box1, it still can penetrate box2.
Thank you!
At first glance, this would be a simple solution:

However, in order to update the position of the box, I had to call releaseDrag. This means that it will stop dragging as soon as there is a collision. It also means that you have to make sure to drag it away from the other box, when you begin dragging it.
I’ll see if I can give you a better solution in a few minutes, as I got some other ideas.
Edit:
I came up with a solution that uses 2 boxes for box1. One representing its collision shape and another representing it’s visual. That way you can decide when you want to update the position of the box.
