Drawing on an Object

I wouldn't even know how to do this with the normal runtime, so I would be intrested in how to do this too

That's exactly how I do it. You can paste to background as an obstacle or platform while the mouse key is pressed. I am creating a faux physics style game where you draw the platforms to guide a ball to a goal. It works really well on the iPhone now too. I do get dots if I swipe too quickly though. I haven't found a way around that yet.

that reminds me of crayon physics deluxe (i love that game!) i actually play it using my Wacom tablet so i can use the pen to draw... i am really intersted in this type of mechanic - keep us posted

Glad you like the idea.
I almost thought of discarding it a while back as there are a few doodle style games on the app store. The only issues I have is the dotty lines (I may have found a way round this though), the misbehaving pinball object and an issue with dissappearing lines when they are out of the camera area. The lines go away visually but the ball still bounces on their invisible ghostly leftovers. Any one have any ideas? Thanks.

Good idea. I tried it myself and found out that you should use fading circles like this: Please login to see this link. as the PAINTOBJECT. Maybe put a little add fx on it so the illusion of a line starts to happen (hmm funny... am I soundling like Bob Ross?). But a good and simple idea! Thx.

You could get around the dots problem by getting the current coordinates of the touch and the coordinates it was on during the last run through the event loop, and creating objects along the line between the two points. (Admittedly I'm making this sound more simple than it is!)

Yea this is something I´d love to see ( I havent managed to create the "in betweeners" yet). If I find out a way - I´ll post it here. At the moment I work with the faded dot and "slower" moving mouse... or finger

Whenever I'm trying to draw a line, each time the mouse moves I resize and rotate the object to the size and angle between the point where the mouse was in the last loop and the point where the mouse is now. You get Fruit Ninja-style vector lines when you swipe too fast. Works well.

i'd love to see an example of that DistantJ...

Could someone post an example of how to do this? I am trying to create a notepad to record student work and would love to see how this can be done with ios application.

Thanks in advance.
