Hi, I was wondering if someone could point me in the right direction or provide some tips on if it's possible to program a mouse pointer that the user can move around on top of a hires graphic on an apple iic in Basic (I'm using a iigs emulator for development and then I copy out to a disk for testing on an apple iic)
Using code from the book below, I was able to get a mouse working and got it's X,Y and status, and I can also have the mouse draw one top of a hires graphic. But I'm not sure how to go about having the mouse pointer move overtop of the graphic without leaving a trail of pointers behind.
I've been thinking maybe I need to do page flipping, or keep a copy of the image in ram and copy it back to a$2000 each time the mouse moves, or use a shape table, but I'm new to programming on the apple iic, and was wondering if someone might be able to point me in the right direction so I don't go down a rabbit hole. Ideally I'd like to do it in Basic since I really don't know what I'm doing in assembly.
