how to switch the projectile def a turret is firing?

[doctercorgi]

I want to make the molten cannons from Rimsenal have an indirect firing mode, allowing them to function as mortars. I have the def for the bullet, but I cant think of a way to make the gun change between bullet defs by flicking or toggling it, any ideals?

As far as I know this isn't doable within XML, you'd need C# code to tell the mortar to switch weapons.

To C# code then!... And several how to videos.
