Thanks guys, however, doesn't really solve the problem. Let me further explain what I meant and how I was thinking to solve the prob:
Basically the Undead unit would be needing to have 2 different ID number, of which would be:
ID-X: The undead unit itself (planned to used the hidden unit of the broadswordman for that)
ID-Y: The dead unit-ID of unit X, but instead of decaying/ rotting this would be a "new" unit with the original falling/ dying slp of the Undead unit just verse-vise giving the impression that the Undead is just getting up again and back to life.
And now comes the tricky part: How to getting from unit-ID Y back to unit-ID X, so that the undead is fighting again? What basic unit to use?!
As for the timer, usually the decaying sequence takes quite some time until it has rottoned forever, so I was thinking of just shorteing the actual decaying time Timer for the "re-awakening" of the undead.
Hope that the explanation now is somewhat more clear as I gues the first question I was posting was not.
Any idea? Interesting and tricky, isn't it? :-)
