WTH does this action do?

Unit - Custom Value

I have no idea what it does or means...

it set a custom value to a unit :p

i never used this before but you can give units numbers whit that, first add a value (lets say 1) to some units, the you can pick all units that have custom value 1 and do action whit them

thats how i understand it :\

Its a property of the unit that has no game use. I.e. A unit has HP, and mana those are properties he also has his custom value, this is the one you can set.

Custom value is usually used to add additional gameplay elements that are entirely gameplay driven. One good example of custom value usage are ammo counters.

I wonder why I stopped using custom values it is actually really useful (hmnn I stopped using them because I now use handle variables, oh right)

Actually. I never understood custom values really well. Im Still confused...
