Forum > Changing the Origin of a Sprite

As I mentioned somewhere in teh Annals of Robs Blog, its necessary that I change the origin of the sprite for Collisional purposes later. At the moment the reference point is at 0,0 in the upper left corner, I would however like to do it at the exact centre point of the sprite so...
spriteName.Width/2;
spriteName.Height/2;

The main reason for circle to circle collisions which is what I swear by for speed and accuracy purposes and for the rotation of sprites also !

Any help will be greatly appreciated, the only reason I am re-asking this is because Rob said something along the lines of not possible...

Thanks in advance !

Oh, ye of little faith!

XNA doesn't really have the concept of a sprite as such, it has commands you can use to position textures using rectangles. You can fiddle with the origin of a draw (mainly so that you can make a texture rotate about any point in it) but if you want to make a "better behaved" sprite it is down to you to create the objects that have the required behavior...

You are indeed very cryptic!

I'll look closer at variations of the Draw command. Also, glad to know its possible.

Should I not be able to find the correct one however, what are the pre-programmed collision systems in XNA like ? Does it have, Pixel Perfect, bounding box, rectangle collision or in built Circle to cicle collision ?

I just prefer defining stuff myself you see, since I write it myself, I know it works...or know it doesn't work and can work out what to fix.
