My tool needs an overhaul right now, so as odd as it sounds, I’d wait till I get off my duff and fix it.
Lots of folks have asked for the ability to change the background, but I keep ‘not finding the time’ to do this. Also, what I want is to convert it to a desktop tool.
Note: My tool and the editor from 71Squared are for editing particle definitions used by Corona’s particle emitter object.
Caleb’s library (cbeffects) is different. It uses textures and objects to create particles, making it flexible in wonderful ways.
Both particle approaches are good, but you should choose the one that is most effective for your goal.
