Easy Question (I hope)

A PocketC native palm library offering native forms and assorted utilities

Postby guilly on Mon Jun 30, 2003 8:36 am

So, let's say I have got a picture background and, i.e. a walking man. What technique should I use to make the man move around the screen without erasing the picture background? (I say, it IS a picture, not a simple color background).

I thought of many uses with the Buffer functions, but I'm still TOO novice to have figured out the how to.

Thank you every body! :)

I would suggest using a single or double buffering approach. Double buffering is a bit slower, but is smoother (has less flicker). See the graphics.c file in the PToolbox release (in the sample_code directory).
