[Snippet] ReviveUnit

Revives a unit in a similar fashion to reviving a hero. Note it does not work on units who do not leave a corpse (e.g. exploded, does not decay etc.).

Here is the code:
library ReviveUnit /* 2.0.0.0
***************************************************
*
*   Resurrects a unit from his corpse, retaining
*   its handle ID, facing, and position.
*
***************************************************
*
*   ReviveUnit(unit whichUnit) returns boolean
*       - Resurrects the input unit.
*
***************************************************
*
*   Configurables
*       - Remove the ! from //! after saving.
