Transport Cargo Ability

[ShadowHunter291]

What I'm trying to do is create a dropship that must be landed to pick up units. So far, I've managed to create something pretty close, but its sloppy and doesn't have the feel I'm looking for. I'm trying to avoid triggers as much as possible, but can't seem to figure out a good way to do this.

I'm going to post the map, and would greatly appreciate the help!


All the requirements I'm trying to get for this dropship ability:
- Can only load while landed
- Can load both player and allied units
- Units can board dropship with right click, but only when dropship is landed

Other features I'm trying to get, but aren't exactly priority:
- Allied units can exit dropship without dropship owner needing to unload them
- Allied units can board dropship with right click
- Dropship cannot force allied units to board it


Thanks in advance for any help!
