I've tried giving the AP minelayer the APC's gun, but whenever it tries to fire, the game crashes.

I have a feeling this might be due to the minelayer behavior being different (holding control allows you to highlight a patch of land to be turned into a minefield) so i'm wondering if anyone else has got it wrking and if not, if there's any workaround.

The mine is just another actor, so while I haven't tested it, I cannot really think about a reason why it shouldn't work.

From what I'd guess, you added an Armament without an Attack* flag (I might suggest giving the mine a turret/use AttackOmni). Post your exception.log.

Yeah, I suspect this was the issue. I got it working by making the minelayer use the APC image.

You are probably missing a muzzle sequence then.

Could you paste your code / crash report, please?

Yeah, it's the muzzle sequence thats causing the issue

You forgot to adapt the respective mods/*/sequences/*.yaml file. https://github.com/OpenRA/OpenRA/wiki/Sequences gives some background.

Or just remove "MuzzleSequence: muzzle" (from "Armament") and "WithMuzzleFlash".
