@ jumble array… i experimented, it seems that when you remove instance, the lower array index moves up…
so in 0,1,2,3 and you remove 2, the 3 will become the new 2, index 0 and 1 is untouched…
yep, you got it. 
anyway, ill look up your recent post, and see if i could experiment and play with it… see if i could learn something from it.
- yeah, im really confused… but heck, we all do, just have to break the barrier, someday ill get it…
good luck to all of us
thanks for more info … i tried to check your project, but i got more confused…
distracted by all the other datas… but man… your work is very impressive!!
