A little Jass function help

[The_Silent]

Well i'm not that good using jass yet and need to do 2 things i've so far found no way of doing on my own.

1: I need a way to "connect" two units two each other, an example would be if the "airport" dies, the currently docked copter would die two, and as long as a copter is docked, anouther copter can't land and dock inside it.

The second is how to disable usercontrol of a single unit, so that is still able to perform orders, just can't be ordered by anyone, but through my triggers. Tried to make it neutral passive and use the follow through time function on the channel spell, but neither worked.

I'll reward any help with rep ofcause

Initialize a hashtable, for example

hashtable hash = InitHashtable()

Link the units:

call SaveUnitHandle(hash, GetHandleId(u1), StringHash("target"), u2)

^You save unit u2 for unit u1 in hash as target.

Then you can load the target:

set u3 = LoadUnitHandle(hash, GetHandleId(*some_unit*),StringHash("target"))
