So, I had a go at this. Here’s my test stack: go url "http://colin.scienceninja.com/colorwheel.livecode”
Choose the browse tool and click the button. The script deletes any existing graphics and then makes 315 new graphics, with the forelock set to a calculated amount. There’s one difference from what was asked for, because angles start from the east, not from the north. In my example red is to the right, blue is lower left, and green upper left. Like, 3, 7, and 11 if it was a clock. I suspect I have something reversed, I wanted green to be where blue is. But still, it’ll show off the idea. Here’s the button script, take a look at it for a while, and the stack, then ask questions! on mouseUp lock screen repeat while the number of graphics > 0 delete graphic 1 end repeat repeat with a = 1 to 315 new graphic set the width of graphic a to 10 set the height of graphic a to 10 put (a-1)/50 into ang put cos(ang) * 200 into dx put sin(ang) * 200 into dy set the loc of graphic a to 300 + dx,300+dy set the forecolor of graphic a to getred(ang),getgreen(ang),getblue(ang) if a = 1 then put the forecolor of graphic a end repeat unlock screen end mouseUp function getred val if val > PI then put 2*PI - val into val put abs(val) into val return round(max(0,(2/3*Pi - val)/(2/3*PI)) * 255) end getred function getgreen val add 2/3*PI to val if val > PI then put 2*PI - val into val put abs(val) into val return round(max(0,(2/3*Pi - val)/(2/3*PI)) * 255) end getgreen function getblue val add 4/3*PI to val if val > PI then put 2*PI - val into val put abs(val) into val return round(max(0,(2/3*Pi - val)/(2/3*PI)) * 255) end getblue _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
