So this assignment im working on is due monday, but I have a problem with getting View.Update to work properly. I've played around with View.Update and i can't get it to work how I want. I have an object that has 7 layers of shapes/code on it, and whenever i try to make him move in a random direction, the object just flickers, this is what I'm doing to make him move, for x : 0..200 draw blah blah blah %%%original shape%%% delay (5) draw blah blah blah %%%eraser that follows original shape%%% end for What am i doing wrong? |

This is what your code should look like
The general order of operations is draw stuff, view.update, delay, erase stuff. |

I bet this is the line of code he's missing from his program. Without this, View.Update does nothing. |

You can add View.Set ("offscreenonly") ^^^ at the beginning of your loop ------------------------------------------------ and ... ------------------------------------------------ View.UpdateArea (0, 0, maxx, maxy) ^^^ at the end of your loop |
