Defining cargo IDs for cargos
Defining cargo IDs for cargos.
The only graphics associated to cargos is their icon that is shown in the station window, therefore the action 2 you need isn't too complicated.

<Sprite-number>|dec|A sequential sprite number
<length>|dec|The total number of bytes used in this action
02|B|Defines action 02
0B|B|Sprites are used for feature 0B - cargos
<cargo-id>|B|What cargo ID this action 2 defines
01|B|A literal 01 byte
00|B|A literal 00 byte
<set>|W|Number of set to use from the last action 1||
You may note that this is the same as the action 2 entry for vehicles, but with num_loadtypes=1 and num_loadingtypes=0, and only one set number.
