Attacks:Enabling, Disabling, Limiting

Mwa haha I've figured out how to do all of those without using triggers(well..mostly without)! =)

The nightelf ability warclub lets you enable an attack for a specified number of strikes, when you go over that number it returns to your previous attack setup.

There is only one issue with it, it's hardcoded to use a destructible doodad, so if you want to use this you'll need to spawn a destructible doodad for the unit to destroy.

the ancients' root ability can do things like this too, and im not sure, but the orbs enable second attack, which can hit air only and is ranged dont they?

No the orb doesn't, it does things a different way, and root forces your unit to sit in one place when rooted, you can't move him around. This gives a nice way of limiting the number of attacks and giving a unit a new attack. (make the 2ndary attack ranged or don't give a primary attack if you want to require ammo, that sorta thing)

oh, i didnt know root negated movement speed... but anyways, that ammo thing is a really good idea
thx for correcting me

edit: u can specify the war club ability to a different doodad than trees right? or is it hardcoded to trees as well?
