@mrcgkh thanks for sharing this!! I haven't looked at the capx yet, but I assume this is all being drawn to the screen each tick or something - just like the good old days! Makes you appreciate old skool games like "Battle Zone" - the amount of work?!
Thanks czar and level1sb Drawing a line is fairly simple. I just used a thin image and moved image point to beginning of line. Math part can be used with different types of drawings. But mess is start when you want to draw curves or polygons. R0J0hound created a canvas plugin, but it's not official. I hope that Constuct 2 adds support for this type of drawings.
