That isnt a good enough answer for uses. You have to explain the uses in order for consideration of the implementation of the element. I do see a potential problem with this element already though, what is there to stop the clone from cloning its self?
But powdered clone touching other powdered clone would actually have the possibility of cloning its self due to the fact that it can actually move around.regular clone and breakable clone cant due to the fact that you are placing a solid object.
Or...
Set the tmp of clne/bcln/pcln/pbcn to determine the state of matter --pcln/pbcn have life 10 when activated, so we can't use life.
0: Normal
1: Powder
2: Liquid
3: Gas
This should be no more than a few lines of code (but I may be wrong), here's some pseudocode:
if tmp of clne/bcln/pcln/pbcn==0:
state of particle=solid
if tmp of particle==1:
state of particle=powder
if tmp of particle==2:
state of particle=liquid
if tmp of particle==3:
state of particle=gas
