Spring RTS Engine

Is it possible to:
- See more than one unit at a Transporter?
- Units can fire while transported?
- Can a transporter have weapons while or not while transporting units which are firing?
- Loading of units like subcom transporter or from Starwars the droide transporter?

Extra questions:
- Can a building add new weapon slots while ingame?
- Can a building take weapon types from a unit?
- Is it possible to create/remove custom icons to a unit/building while ingame?

Units can fire from a transport if isfirebase=1 is set, several mods use it already.

Thanks, for the answer KDR_11K. But there are still some left. Sorry for asking but Iam a lua beginner.

For all your questions beside the fourth and the seventh, I'd use BOS/COB instead of LUA. But maybe that's just me.

1. trepan already wrote a widget that shows you the transported units (see ca)
2. answered
3. see the corbtrans/vinidcator in ca (imo you can check if the unit transports atm, so you can also deactivate weapons during transporting iirc, if not then it still is possible with lua)
4. duno

a. not with single units imo
b. /
c. there is a widget that replace all icons with custom icons -> so, yes
