Anyway, so my question is this: could a similar approach (manually specify corners of quad) be used in combination with your approach (sprite points)?

Or maybe there is a ‘better’ way to do it perhaps?

Firstly let me just say your tutorials are amazing – keep up the awesome work!

I have a question regarding particle systems -more specifically about your point sprite implementation. Is it possible for point sprites to be drawn at a rotated angle? For some particle effects like smoke it looks cooler if the particles are rotated!

If this is possible could you help me out with it?

Thanks in advance,
Peter

ps I can’t take any credit for the DebugScope tool. It was written by another ex Bizarre Creations guy who now runs PixelBalloon (www.pixelballoon.com).

We wrote our own network code to remotely control a particle emitter on one or more real devices direct from Particle Designer. It was working great but we could not get rid of some stability issues and ran out of time to get it working.

We are working on Particle Designer 2.0 at the moment and this project may well be able to help out.

Cheers

I just wanted to point you in the direction of a cool open source tool that you might find useful. It’s a realtime debug variable tweaker that lets you change variables in realtime of your iPhone/iPad app.

It requires you to add some code to your iPhone projet but the code is lightweight and can be integrated in 10 minutes and once the code is integrated the tool just needs the iPhone’s ip address to communicate.

You can expose variables by declaring them in your code with a special macro and once exposed you will get a slider bar in the tool for each one. It even supports colours with a colour picker.

I’ve only got one problem, that i haven’t been able to solve:
If i use the EAGLEView as a normal UIVIew (inside another UIVIew) everything works fine and as expected, but if i re-instantiate it a second time (having released the first EAGLView before), the particles do NOT get rendered on-screen.
I’m rather new to OpenGLES, so forgive me if this is a dumb question.

thanks
