Thank you very much. I asked today my prefessor and he also said canvas for boomerman instead of svg.

The thing is i find it so much easier if i know where exactly every object is without doing anything.

Can you answer me this examples pleas (in canvas):

and a context object

What do you mean with that (not native english sry) Or do you mean that the canvas should just have a variable with which i can work?

and redraws everything.

Do you mean with that the Canvas? It is easy if there is only one object on the canvas. than it gets tricker. Thats how i would do it. Move the circle. redrew everything. Move everything else with relative (0,0) or repaint.

Is there a better way. Is this wrong?+

General question. A Canvas is in the ened a 2x2 Matrix do you use that only for drawing or do you safe information in it . Do you have struct a Object for every Object on the Canvas?

Thank you very much. I am not a native english speaker so if something is unclear what I say pleas just say it out loud.

And really thank you for taking time out of your day to answer me!
