How do I make game effects..

I was hoping to learn how to create the effects I see in games like contra etc but also bejeweled and other games..

Does anyone know where I can learn to do this? cant find anything on youtube..

definitely need to be more specific... you can do millions of different kinds of "effects"

I want to be able to sparkle effects, smoke lightning fire etc.. explosions.. In bejeweled the gems glow and sparkle.

Insert object -> use the Particle object.

search the forums and tutorials, there's dozens of examples... and check in C2's /examples folder.

you can also use sprites...but you have to do a little more work to make them do what you want... Particle Emitters do that for you.

Thank you very much...
