I have a sprite system which uses groups. A group could be one sprite, or it could be 100. I could have 1 group or I could have 100 groups.

Do you know if I can use the Sprite Physics SetSpriteGroup() to register my own group number without "switching on" physics? It will make my non-physics hit tests so much faster if I can narrow them immediately by group ID. My only concern is that it will switch on physics functionality that I don't want.

It's a very simple answer: Yes

The help text for SetSpriteGroup specifically says it is for physics or non-physics.

This allows you to use commands like GetSpriteHitGroup (which doesn't use physics) to see if an x,y point is over a sprite in the group.

Assigns this sprite to a group for filtering collisions (physics or non physics)

If I was younger, I think I would be calling this a facepalm. At my age it's simply being a 42 carat plonker.

Thank you
