Can Gideros display emitters saved in the standard Cocos2D format (.plist)?

Mells · June 2012

Hi,

I am asking because I have downloaded Particles by Tunabelly Software (currently free) and was wondering if the particle emitters created could be imported in Gideros?

Description :
Particles - An intuitive and easy way to make particle emitters for Cocos2D.
Emitters are saved in the standard Cocos2D format so they can be easily imported into your app or game.

@atilim I have no idea if this is feasible or not, just asking

Files are saved in .plist format and here is a sample :

That app just creates template files for the built in Cocos2D particle system.
To get those pList's to work you'd need include / emulate the code from Cocos2D.

I suspect it'd be too heavy to do in Lua (especially for a lot of particles), however it might work as a plugin, whereby someone could put a wrapper around the Cocos2D code and have it render to a separate view like the way the UIKit plugin works.

The only downside (if it is a downside) is that the particle "layer" would always be on top of the Gideros display and it wouldn't be possible to mix the two..

That said "if" the Gideros team were looking to implement a native particle system any time soon, then the Cocos2D one might be a good place to start.

Well you could also ask @GregBUG if it could be possible to interpret file and emulate it in TNTParticle Engine

But he's on vacation now

It'd be more efficient to convert the plist to something that would work in Greg's TNTParticle Engine. There's lots of plist utilities, it's very easy to understand.

Ok, let's be patient then
