Changing Magikoopa Spawns

[ANueUtsuho]

Is there any way I could alter what Magikoopas turn Flip Blocks into? I'd like to get rid of the Fighter Flies, or just make them spawn less often.

Load npc-300.lua in your lua file, and change the contents of the "transformations" variable (they're NPC IDs). Here's the loading code with the list set to what it currently is. Every entry is equally likely to appear.
local magic = require("npcs/npc-300")
magic.transformations = {54, 112, 33, 185, 301, 165}

Load npc-300.lua in your lua file

This isn't possible to do. Attempting it load npc-n.lua files produces an error.

This particular NPC had an oversight when converting it to npc-n.lua, and this should have been moved into their NPC config. This will be fixed in the next patch.

Ah, darn bugs.

Until then you can get the same effect by copying npc-300.lua to your level folder and renaming it to npc-751.lua, and copy the magikoopa magic image sprite to the same filename too. You can then use npc-299.txt for the magikoopa to set "magic=751", to make the magikoopa shoot the new custom magic NPC.
