So I went through my old scripts at www.wc3jass.com and found this one. I decided to remake it as a library with some minor improvements. The IsDestructableTree function should come in handy for certain spells and systems. It works for the standard trees as well as custom trees (destructables based off trees). I've also included IsDestructableDead for completeness. It uses the unmodified footman as a dummy with the ghoul harvest ability, so there are no changes in the object editor required.

Code: jass

//* I made this to detect if a destructable is a tree or not. It works not only  *
//* for the standard trees but also for custom destructables created with the    *
//* object editor. It uses a footie as a dummy with the goul's harvest ability.  *
//* The dummy ids can be changed though. I also added the IsDestructableDead     *
//* function for completeness.                                                   *

globals
    private constant integer DUMMY_UNIT_ID = 'hfoo' // footman
    private constant integer HARVEST_ID    = 'Ahrl' // ghouls harvest
    private constant player OWNING_PLAYER  = Player(15)
    
    private unit dummy = null
endglobals
 
function IsDestructableDead takes destructable dest returns boolean
    return GetDestructableLife(dest) <= 0.405
endfunction
 
function IsDestructableTree takes destructable dest returns boolean
    local boolean result = false
    if (dest != null) then
        call PauseUnit(dummy, false)
        set result = IssueTargetOrder(dummy, "harvest", dest)
        call PauseUnit(dummy, true) // stops order
    endif
    return result
endfunction
 
private function Initialization takes nothing returns nothing
    set dummy = CreateUnit(OWNING_PLAYER, DUMMY_UNIT_ID, 0.0, 0.0, 0.0)
    call ShowUnit(dummy, false) // cannot enumerate
    call UnitAddAbility(dummy, HARVEST_ID)
    call UnitAddAbility(dummy, 'Aloc') // unselectable, invulnerable
    call PauseUnit(dummy, true)
endfunction
endlibrary
 

I've also included a test map with standard and custom trees to validate the script. It's not too exciting though.
Can you think of anything else that could be useful in a DestructableLib?
