Discuss game development here, from a distinct game project to an accessible third-party mutator, down to the interaction and design of individual units if you like.
It turns out that in Spring, no fancy scripting is required to make aircraft transport multiple units. That was a TA limitation that is no more in Spring. See with Gnome for details.
The Naked Santa and Silly Tipping Over Rocket Man are 2D units. They won't look good in Spring 3D engine.
Yeah, nothing special required. Just increase the capacity of units it can hold in the FBI, and bam, done.
Now, if you want to attach units to different pieces in the transport so they are arranged in formation, that takes a little bit of scripting, but nothing much. But I already showed you that script snipplet in the WD topic...
