oslib help - deleting images off-screen and duplicate images

[Dark_Sabre]

Well I've been thinking that since I'm going to need to know these for a project im working on could someone please show me how to do these two?

You can't just delete images off the screen... Just use a clear screen function or whatever. Also, what do you mean by duplicate images? If you mean drawing the same one twice just well... do that.

[Dark_Sabre]

that works? hmm..... and by deleting say for after drawing it say it goes off screen how would I get rid of it?

[Blade_punk]

Do you mean remove it from memory? If so use oslDeleteImage().
If you dont want it drawn at all just... Dont draw it.

I mean say e.g. a bullet is shot from a ship and it collides with something, what would get rid of the image from the screen and yet still let me use oslDrawImage (I think thats it)

[Scorpus]

No, that removes the image from the RAM so you would have to reload it again if you wanted to draw it again

[Blade_punk]

Not drawing the image doesnt remove it from the memory.
If you wanna draw the same image maore than once just use
oslDrawImageXY(X, Y, whatever) more than once with different coords. In regards to removing from the screen something basic would be:

int blit = 1;
image = blah;
while(1)
{
	if(blit == 1)oslDrawImage(image);
	if(something happens)blit = 0;
}
