[Trigger] Help with Hero level detection trigger

[PrimoCurby]

I need a trigger which give lumber to a player each time his hero gains a level.

I already have a trigger, a simple one:

Events
Unit - A unit Gains a level
Conditions
Actions
Player - Add 2 to (Owner of (Triggering unit)) Current lumber

But there's a problem, in my map, if a hero kill a boss, it will get more than 1 level at once, and the trigger will not give the propper amount of lumber, for exemple, if the hero gains 3 levels at once, the trigger will detect just one level, and will give only 1 lumber.

Hope somebody can help me, thanks.

Make an integer variable called LastLevel (default value 1), and a temp integer, let's call it LevelChange.

Events
 Unit - Unit gains a level
Actions
 Set LevelChange = hero level of triggering unit - LastLevel
 Player - add (2 * LevelChange) lumber to owner of triggering unit lumber
 Set LastLevel = hero level of triggering unit

That should fix it, but if I may, I think gaining more than one level at a time is bad design and should be avoided.
