Is a smooth drawing app possible in GS?

JCFord

I am looking to create a children's drawing app, the type where you can select colours from a side palette and then freestyle draw on the screen with your finger etc.

I have seem that there are a few drawing apps / demos on the GS site, but they all seem to have an issue that if you move your finger across the screen quickly that the spawning effect is playing catch up and this ends up with an inconsistent line being drawn.

Is it possible to create this kind of app that can create a smooth drawn line with GS?

Thanks

To my knowledge, I don't believe it is unfortunately. I havent much more to say sadly.

If you feel like dipping a toe in Obj-C / XCode - Apple does provide a fairly robust example project. Which, with a little tweaking and twiddling you can do a Drawing/Painting App.

Hi Wayne I had a quick look at the GLPaint you suggested, but to be honest - Xcode, I wouldn't have a clue, so I will just have to see what I can come up with in Game Salad, but I don't think I will be able to get the smooth paint like action from the spawning - but thanks for your time.

from what I can gather, if you use Cocos2D libaries, you will find programming iphone GL graphics a lot easier, see the example code here for that kind of app...

Hey JCFord. You might be able to bully this into something. You won't get any line breaks, but, well you'll see the limitations. But if you have a thick pen, with rounded edges you should get a reasonable result...
