Alright, I'm a rather huge turing newb making an "animation" for my computers class.

All I want is some text to move across the top of the screen. If I don't use cls, it's just a big black line (obviousely.) If I do, it makes the text flash on and off everytime it goes through the loop.

Anyone have a remedy?

use View.Update, there is a pretty good tutorial on this site somewhere.

cls erases everything and than you redraw the thing again that is why it is flashing.

When you declare graphics mode, make sure to use "offscreenonly" that way the image is pasted on, instead of erased and then pasted on.

Okay... this si what you should do. At the very top of program type (or add if you already have a setscreen):
code:
setscreen ("offscreenonly")

And whenever you draw something new (such as each time the moving words move to a new location) you should (right after) this:
code:

View.Update
cls
Hope that helps 8) .

P.S It really is annoying how you cant use two [codes] in this forum. Mad Wink

Mod Edit: Sure you can, see?
Another Mod: eh... first you View Update, then you cls... and stick that after you done drawing frame
Another Another Mod: about that code thing, it dose somtimes cause wired errors, i am still working on it. but i dont got tones of time with school and all.
