i was trying to make a game and i ran into a problem, i need to draw a white circle but i cant figure out how. i figured that the whiteline rotated a bunch would look dumb so i was wondering if anyone know any other methods. i am using xlib but i dont think that that has a circle function. So, any ideas?

it's impossible in BASIC, even with the fast circle command (unless there's another hidden argument). And xlib doesn't have circle function

Are the circles a set dimension or does it have to be any size?
because if they are a set dimension you could use a xLib and a circle sprite to erase it.

yeah, thats what i was thinking, i figured i'd end up makeing some 16x16 sprites. well atleast now they can look like an explosion...

You could draw the circle (except using pixel off or point off), just have to make the calculations

true, but he would need to use lines so it's not too slow

IF someone made an asm Lib to invert the screen you could invertit and then draw the circle and then un-invert it

2 circles maybe, one larger and the other smaller than the intended size of circle.

No that is now what I mean
you start with
00011000
00100100
00100100
00011000
invert it
11100111
11011011
11011011
11100111
then draw the circle again
11111111
11111111
11111111
11111111
then un-invert it
00000000
00000000
00000000
00000000

oh lol you can alerady do inverting with xLIB, Zapi and Codex

[code]
for(x,1,94
for(y,1,63
pxl-chg(x,y
end
end
[code]

lol

what's Zapi?

Codex ancestor. It featured a non working 8x8 sprite routine, non working 12x8 map routine, which saved maps as 8xp files (using chaos asm compiler (which doesnt work)) , a non working picture storing feature (allowing to save pics as 8xp files) and a working multi size sprite routine. It also had a working stand alone program with many features found in codex and a scrolling routine with some nifty features (altough buggy)
