Hi all,

How do you make the background (color) flicker, in otherwords change from black to red then back to black without destroying whats displayed on the screen like text or objects?

Thanks.

You could put up an image (screen's height and width) and run an if argument on an the incremented variable of the image's number. Make sure, then, to put this before any of the text.

Plain object in the background, use the color object command, render any other objects you want in front of it. Here's an example placing a background plain at 100 units from the camera and fades it from black to red and back to black:



Edit: Updated code to include some text and a few objects to show how it works without over-writing those graphics.

umm not exactly what i wanted. I want ONLY the background to change. In other words make the background change colors without effecting the foreground (text) somewhat like an explosion or hit effect.

like this....

cls rgb(255,0,0)
wait 100
cls rgb(0,0,0)

only when i do it this way it clears all the text. I want something that DOESN'T do this.

Thank you again

backdrop on
color backdrop rgb(255,0,0)

However, if you're not redrawing whats on screen every loop, this will also clear it.
