creating a plant

[pixelface]

Hello,
this time I'm having trouble to grow a plant on a specific type of node.
The coral grass should be spawned on top of the coral block.
I'm getting this error message inside the client:
And there is no coral top showing up.

That is the code:

Thans for your help! :)

What are you trying to do ?
The ADM defined here (the first and second one) pops a blue/pink coral above a dirt node if there is water near the dirt node. Is it what you want ?

I'd like to spawn the pink coral grass ontop of the pink block.
This does not seem to work.

The change+intervall should be lower for the pink grass, so it can find a free pink block to spawn no top of it.
The code for this is below the pink and blue spawnig block code.
But, well, the grass dosen't show up.

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_craftitem("korallen:pink_coral_grass",{
   description = "pink colored coral top",
   inventory_image = "koralle_top_pink.png",
   wield_image = "koralle_top_pink.png"
   --on_drop = function(itemstack, dropper, pos)
   --itemstack:take_item()
   --return itemstack
   })


minetest.register_abm({
   nodenames = {"korallen:pinkcoral"},
   neighbors = {"group:water"},
   interval = 45,
   chance = 50,
   action = function(pos)
      pos.y=pos.y+1
      minetest.add_node(pos, {name="korallen:pink_coral_grass"})
   end,
})

`korallen:pink_coral_grass` is registered as a craftitem so it can't be placed as a node
You have two solutions :
1) Register `korallen:pink_coral_grass` as a node
2) Don't modify `korallen:pink_coral_grass` and drop an ItemStack with minetest.add_item

Thanks for your answer! :D
What's the best way to add it as a plant? I've never created a plant-object in minetest before.
I'd like to have something similar to the the grass that's growing on dirt in the regular game.

Probably something like this (this code is in minetest_game/mods/default/nodes.lua)

Your phone or window isn't wide enough to display the code box. If it's a phone, try rotating it to landscape mode.

Code: Select all

minetest.register_node("default:grass_1", {
   description = "Grass",
   drawtype = "plantlike",
   waving = 1,
   tiles = {"default_grass_1.png"},
   -- use a bigger inventory image
   inventory_image = "default_grass_3.png",
   wield_image = "default_grass_3.png",
   paramtype = "light",
   walkable = false,
   is_ground_content = true,
   buildable_to = true,
   groups = {snappy=3,flammable=3,flora=1,attached_node=1},
   sounds = default.node_sound_leaves_defaults(),
   selection_box = {
      type = "fixed",
      fixed = {-0.5, -0.5, -0.5, 0.5, -5/16, 0.5},
   },
   on_place = function(itemstack, placer, pointed_thing)
      -- place a random grass node
      local stack = ItemStack("default:grass_"..math.random(1,5))
      local ret = minetest.item_place(stack, placer, pointed_thing)
      return ItemStack("default:grass_1 "..itemstack:get_count()-(1-ret:get_count()))
   end,
})

Thanks a lot! :D
I'll try that.

I think the problem is you created a craftitem you want to add as a node:

You could try to change:
minetest.register_craftitem("korallen:pink_coral_grass",{
into:
minetest.register_node("korallen:pink_coral_grass", {

Isn't a node always in square form?

No, not at all. http://dev.minetest.net/Node_Drawtypes
