How to make an NPC use a fire scattern pattern

[MightyMonte88]

Hey i setup my NPC system exactly as kallvin did with BasicNPC, however i have been unable to setup a mob to fire anything other than a single projectile...., below is a snippet of the weapon file the mob is using. This mod is supposed to fire pellet rounds from a military shotgun, but still fires a single projectile, any help would be greatly appreciated .

While at it, is it possible to add an accuracy variable to them?  The rifle NPCs are crazy strong once they get into range because they hit every unobstructed shot.

Hello!

To fire multiple projectiles, you need to override PrepareFireScatterPreset method. For example, see how the plasma rifle is implemented: https://github.com/AtomicTorchStudio/CryoFall/blob/4a652eb58121d9ff37711e2ee7323c6cae94d09c/Core.cpk/Scripts/Items/Weapons/Ranged/ItemPlasmaRifle.cs#L29

Regarding the randomized accuracy, override method SharedUpdateAndGetFirePatternCurrentSpreadAngleDeg like we've done for Fire Lizard poison spits:
https://github.com/AtomicTorchStudio/CryoFall/blob/4a652eb58121d9ff37711e2ee7323c6cae94d09c/Core.cpk/Scripts/Items/Weapons/MobWeapons/ItemWeaponLizardPoison.cs#L52
