Using Grid or Canvas as sprite containter?

31. January 2009 by Mads

The other day I were reading some great articles about creating a game step-by-step by Joel Neubeck. I looked at the source code and saw that he were placing his sprites different then what I have seen before. I wrote a comment to Joel on his blog. You can read it here.

Untill now I have only seen samples, and have also only done it this way myself, of placing sprites using a Canvas and the attached properties Canvas.Left and Canvas.Top. This have worked fine for others and for me.

By looking at Joels source code I saw that he were using a Grid as his container to hold his sprites and the a TranslateTransform to place them on the Grid.

Well, I know, the outcome is the same, but it made me think if there actually were a performance difference. So I desided to do a little test my self. I build two small Silverlight applications, both with the same content - balls bouncing around. One is using a Grid as the container and the other a Canvas.

You can see the samples live here:

Grid sample

You can download the source code from here.

To me they look exactly the same. As you can see, if you run Firefox, that I have enabled the FrameRateCounter and have set the mas framerate to 9999. On my computer these are pretty much the same all the time. In Chrome I can see the memory useage of the silverlight plugin and that seems to be the same as well.
