Cattails not spawning correctly

[GamingAssociation39]

So as the title says I'm trying to get my cattails to spawn in only one block of water and the have the drawtype "plantlike_rooted".

Code: Select all

minetest.register_node("ws_core:cattail", {
	description = "Cattail",
	drawtype = "plantlike_rooted",
	waving = 1,
	tiles = {"ws_cattail_bottom.png"},
	special_tiles = {{name = "ws_sandy_dirt.png", tileable_vertical = true}},
	inventory_image = "ws_cattail_plant.png",
	paramtype = "light",
	paramtype2 = "leveled",
	is_ground_content = false,
	groups = {cracky = 1, level = 2},
	walkable = true,
	selection_box = {
		type = "fixed",
		fixed = {
				{-0.5, -0.5, -0.5, 0.5, 0.5, 0.5},
				{-0.1,  0.5, -0.1, 0.1, 2.0, 0.1}
		}
	},          
	
	node_dig_prediction = "ws_core:toxic_water_source",
	node_placement_prediction = "ws_core:cattail_bottom",
	sounds = ws_core.node_sound_metal_defaults(),

	
	on_place = function(itemstack, placer, pointed_thing)
                                                
		local pos = pointed_thing.above
		local depth,sytpe,surface = ws_core.water_depth(pos,20)					-- max must be specified and >12 or buoys will always be set
