Making new illumination rockets, can't nail down why they don't work

Xeno426 · February 7, 2024

I've been attempting to create several extra warhead types for the Zuni, basing it off the existing Zuni values. While the HEAT and smoke rounds work fine, I've found the illumination rounds to be confounding. So far I've got something that doesn't crash the game on startup, but other rockets on the aircraft won't fire and trying to shoot the illumination rockets crashes the game without any obvious errors in the log. Though on startup, it gives me an odd error in the logs.

ALERT   wInfo (Main): While loading weapons.nurs.ZUNI_MK33_OV10: Error while loading ./Scripts/Database/Weapons/schemes/rockets/nurs-light.sch: Parameter not defined: launcher.server

Here's the current code I've got for the illumination rockets.

I've tried adding explicit entries for both Client and Server, but that hasn't had any effect either. Though it does have the advantage of not causing crashes when trying to fire: it just doesn't fire at all.

Has anyone else been successful at creating their own illumination flares or rockets? It'd be nice to look at something that works to compare and see where I've gone wrong.
