How to make an trigger when the unit leaves a transport?

[BrianBarsaski]

For example, while the unit is in a boat, it have a Arrow Key Movement, okay, then it leaves the boat, the Arrow Key Movement desactivates...
Specifically, the Arrow Key Movement is that: Flexible Arrow Key Movement System
Please, I need urgently!

You would have to keep track of all units that are inside a transport and periodically check if they are still transported.

There should be a system in the spells/systems section that does it.
At least I though there was.

Bribe's GUI Unit Event should do the job.

I would use a loop and check if unit is loaded.
Not worth having a system for one unit.

Not worth having a system for one unit.

The system does a lot more useful things than just check for transport units
