Drawing Shapes in AHK (Proof-of-Concept)

(1/1)

Masonjar13:
I wrote a function for someone on one of the AHK forums to get coords based off known coords, length, and angle. I then decided to play into it a bit and draw some shapes. Here's a pretty good demo I made, although, please note that for polygons, it will never have more inner-vectors compared to the outer-vectors, because I wanted it that way  :Thmbsup:

Instructions:

*  Run script
*  Open a new paint window, full-screen
*  The rest should be self-explanatory (starting coords are always the center of the screen)AHK-Draw Demo

The hotkeys are Shift+1 to bring up the main gui, Shift+2 to instantly interrupt the drawing, Shift+3 to kill the script.

I encourage modification of this code, but request acknowledgement if my function is used elsewhere, thanks!  8)
