Custom Race Lumber Harvesting

[Masih Shadowmind]

Hi everyone, this was supposed to be an easy thing but when I started working on triggers I found out that it's almost impossible! all I wanna do is to force workers of a certain race to only harvest from Crystals instead of trees but other races can harvest from both crystals and trees. it feels like there is no way to detect if worker is harvesting from a tree. does anyone has any idea?

You could detect when a unit is issued an order targeting a Destructible.

If the unit is equal to the worker you want to harvest only from Crystals, then you can check if the Destructible isn't a Crystal. If it's not, you can order the unit to Stop and, depending on how detailed you want to get, you can play an Error sound byte and display a custom error message to the player.

The only real issue with this approach is that forcing a Stop command will interfere with queued orders, but outside of that this should work for you.
