strange physics collision bugs

[SirEatAlot]

For years I have been having constant problems with physics and collisions in my game.
I have finally managed to track some of them down at least when and how they appear.

Question: Is there a way to have a physics object at a fixed angle that never rotates but still collides and interacts with physics?

It seems like it, just dont check "auto rotation" right? Nope. The object no longer rotates - but the physics collision mask still does! And you cant actually tell that anything is wrong until things start to collide with your object in very strange ways.

Also going through and selecting different physics collision shapes both with and without "extended collisions" checked causes strange behavior.
Sometimes the top half of the object is not recognized, other times certain the collision marks is enlarged more than the object, other times certain parts of an object is ignored, etc.

I have made an example of these problems, plz would really appreciate verification so that it's not me going crazy.

Don't use bounce with physics use Stop on both objects
For drag & drop in Physics use Physics static movement

Sorry but I think you're missing the point.

I'm not looking to use a drag and drop movement, that is just for testing purposes.

Im trying to make a keyboard and gamepad controlled movement of a physics object that does -not- rotate. (side scrolling shoot em up)

Im not using bounce on both objects.

And the object itself is not rotating while its collision mask is, clearly this is not how its supposed to work?

Ahh I suspected I might have been.

Does Fixed Angle suit your needs?

It does not, but even if it did, having an object not rotating while its invisble fusion physics collision mask is seem like a very clear bug to me?

Sorry but I'm not really looking for "how to I make a non rotating movement", I'm looking for "this is clearly a fusion bug right?" or an explanation for why its not and is intended behaviour.

I've made this illustration to make the point more clear
