Before Clone index +TOtoal clones came out there was a way to give instructions to individual clones.
Something like this,
Make a variable “ME”
When game starts, repeat 20 times create clone.
When ME = 19, wait 1 sec, set ME to -1
When iPads tapped, change ME by 1
When clones created, set angle to ME
Change ME by 1,
Forever if ME = rotation of clone, DO WHATEVER, change ME by 1
This is a quick example of creating 20 clones and making each clone do something one after another in sequence.
