To simulate a walking dog, I made use of forelayer and image lib (drawer) to erase last area then draw image on new position again. The transparency and partial refresh work fine. However, the refresh speed is slow that I feel my the image is jumpping. Any way to draw image and refresh faster? I am using Dopod D810 WM6, CPU Samsung (R) 2442 with 400Mhz. The timer interval is set to 1 already. Thanks in advance..
