Each paint 'actor' is a round graphic of the same colour, using circle collision. So when the player drags and paints with the mouse, its spawning lots of these actors so it looks like paint - but the 'combined' circle collision kinda gives a smooth ish surface for the wheel to roll over, round, up etc. I put a timer on each spawned actor of 3 seconds, which adds to the challenge, and also makes it drip away which helps keep performance good. (using 3.0 i can get away with alot of actors).. ive never counted, but im guessing its spawning a few dozen actors as you 'paint'.
The game works perfect performance wise and otherwise - aslong as players take notice of 'wheel time', otherwise painting gets tricky when things speed up - but i thought this would be a good gameplay mechanic - allow the player to pause the wheel while you paint ahead, but also limit the amount of paint you can use and how much 'wheel time' you can use up.
Ive put the game up for fgl admin check, and its already come back with a poor score and complaints about controls being too difficult/etc - Im guessing admin failed to take notice of wheel time, which is very important to gameplay, as its there to help you complete a level, not just there for the sake of it. (you cant miss all the popups and info Ive stuck in there helping/informing the player what to do).
