Is there a way to clear just a portion of the screen? say the bottom half? I am doing a little text thing. I am not really into 2D or 3D yet. I am doing this little text program to learn how to use loops and functions. The top half has a title and menu, the bottom half is where the commands and text in the game goes. as new text pops up or new commands are entered everything will scroll up and go into the menu. Is there a way to just clear the bottom half of the screen after so many commands have been typed or after so much game text has filled the bottom half of the screen?

Thanks and Merry Christmas

Doesn't set camera view resolve your problem?


Cheers.

I have not moved into 2D or 3D this is strictly a text program. Is there a way to do it with a cls command or something similar?

thanks!

Unless you make your own function and cls from time to time

That may work, I was thinking about that. I don't really want to clear the whole screen because I don't want to wipe out the menu but I could make the function clear the screen and re-write the menu and other info I want to stay on the screen.

I wanted this to be a strictly text thing but I could delve into some 2D and make a sprite or text box bitmap etc... where all the game text and commands go.

usually easiest to just clear the whole screen and reprint the 'fixed' items just as they were.

Here is one way to clear an area.


Although native 2D commands are unofficially 'obsolete' because of their slow unadorned nature. Use Advanced 2D.

You could also draw a filled box over the area on the screen you'd like cleared. That's probably the simplest method. The Advanced2D command for that would be:

a2fillbox x1, y1, x2, y2, colour

Absolutely love Advanced 2D commands. Not a project goes by where I don't use them!
