Has anyone managed to perform collision detection properly on angled objects like triangles?

I want to be able to detect collisions like the image below, but when I use "set object collision to polygons <object #>" on both objects, the collision is detected far too late. If I use boxes based detection then it will detect too early. If I have one object set to boxes and the other to polygons, then it detects collisions properly for the one, but not for the other. Do I have to get plugins to have proper collision detection of polygon based objects? Well, I did get NGC a while ago, which I might use for this, but I wanted to do it with the regular engine. Also, I'm curious.



Also, see my other post about this in bug reports. Wasn't sure which forum to post this in.

I also posted this in the classic forum by mistake.

The problem with polygon colission is that only 1 object is polygon the other is sphere.

If it's detecting it too early or too late you adjust the size of the collision sphere.

You can set your objects to show their collision areas which normaly makes it all easier to judge.

Probably Dark Physics would be your best bet if you have the money and you want your triangle to fall into place on top of each other free style Tetris like. Unless it's 2D then use an array matrix
