Resize a Body in Phys2D?

Game Mechanics
#1

Hey there –

I created by own subclass of Body that allows it to display images on top of the Body, but because animations change size frequently, every time the subclass draws I want it to refactor the width and height of the Box associated with the Body to match the current frame of the image. The only method I can find is set(Shape, float), but this resets everything to zero, which I don’t want to do.

Do I need to edit the source and make my own method for the Body or is there some easier way to do this?

Thanks.

The change to support this is in SVN - it does have potentially odd results if you resize the body to a size that collides with something else, instant reaction etc.

Okay, thanks Kev.

One question about that: is it terribly inefficient to resize a Body, or not demanding? I do it every single time there is a repaint and with every single Body in my World, which can be from 10 to 20.

Thanks.

It’s pretty inefficent yeah, it’s also a bit dangerous to the physics model (thats why it wasn’t there originally). However, for mootox I needed it (when you change direction) so it’s in there with a warning sign. I’d suggest trying it and experimenting.

Okay, thanks. I suppose I can minimize the changes and only resize it when a different animation starts playing… I’ll check it out.
