Have you looked at my capx...?
Because I do chain (and spawn for that matter) one color at a time, in the event sheet - but I'm not entirely sure that what I've done, is what you mean...?
About particles spawing; what would you suggest as an alternative to spawn/destroy them...? Or did you mean to decrease the number of particles seeded/spawned for each "explosion" (this I wrote a little about under my section "Performance" in OT...)
I know its not a complete game yet, but i guess 1 click shouldn't destroy them all, so limiting by clicking on a red only destroy chained reds, could give the game more dimension. Maybe another option is to make the circles smaller
Yep I saw that performance section. it looks cool to use a particle that spawns a particle object itself but it probably sacrifices too much performance.
Only suggestions nice work!
