Step One

Open the addon editor and name it something, for example "Cargo Testing Addon"

Step Two

Add a new Mission Location and select ocean



Note : The tile name doesnt seem to effect anything but its recommend you name it what the cargo is

Step Three

Open the tile and add the cargo you want. Make sure the X is 0 and the Y is 1.5 with 0 rotation



And that's basically it for the general cargo. But we still aren't done.

Ok so if you notice theres 2 text boxes, the Display Name is what the cargo will display in game. So for example



Now the tags is where it gets Interesting


Tags : type=cargo_package,cargo_type=container,theme=civilian,probability=0.01
Requirements :
X : 0
Y : Level with ground
Z : 0
Standard : ISO
Connectors should be set to disconnect when spawned in


Tags : type=cargo_package,cargo_type=trailer,theme=trailer,probability=0.01
Requirements :
X : Back of the trailer should be in front of the square
Y : Level with ground
Z : 0
