how to delete an entity?

[Mito551]

is there a function to delete an entity? to remove it, to kill it?
like

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.env:add_entity

but

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.env:remove_entity

is there a function to delete an entity?

Yes, it is.
self.object:remove()

oh well. so i need expanded help then.
i have this thing here:

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

--the flame entity
minetest.register_entity("torch:flame", {
    physical = true,
    visual_size = {x=0.3, y=0.3},
    collisionbox = {0,00,0,0,0,0},
    visual = "sprite",
    textures = {"flame.png"},
    on_step = function(self, dtime)
        self.timer = self.timer + dtime
        if self.timer > 2 then
            self.object:remove()
        end
    end,
    timer = 0,
})

-- register flame abm
minetest.register_abm({
    nodenames = {"torch:torch"},
    interval = 1,
    chance = 1,
    action = function(pos)
        if minetest.env:get_node(pos).param2 == 0 then
            minetest.env:add_entity({x=pos.x,y=pos.y-0.25,z=pos.z}, "torch:flame")
        end
        if minetest.env:get_node(pos).param2 == 1 then
            minetest.env:add_entity({x=pos.x,y=pos.y+0.3,z=pos.z}, "torch:flame")
        end
        if minetest.env:get_node(pos).param2 == 2 then
            minetest.env:add_entity({x=pos.x+0.43,y=pos.y+0.4,z=pos.z}, "torch:flame")
        end
        if minetest.env:get_node(pos).param2 == 3 then
            minetest.env:add_entity({x=pos.x-0.43,y=pos.y+0.4,z=pos.z}, "torch:flame")
        end
        if minetest.env:get_node(pos).param2 == 4 then
            minetest.env:add_entity({x=pos.x,y=pos.y+0.4,z=pos.z+0.43}, "torch:flame")
        end
        if minetest.env:get_node(pos).param2 == 5 then
            minetest.env:add_entity({x=pos.x,y=pos.y+0.4,z=pos.z-0.43}, "torch:flame")
        end
    end,
})


and i need to register another abm to remove it. how would i do that?

I'm not sure what do you want to achieve, but to remove an entity of a particular node I did this in my "gauges mod":
Entity definition

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

local furnace_bar = {
    physical = false,
    collisionbox = {x=0, y=0, z=0},
    visual = "sprite",
    textures = {"20.png"},
    visual_size = {x=14/16, y=1/20, z=1},
    wielder,
}

Entity creation func:

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

function add_furnace_gauge(pos, newnode, placer, oldnode, itemstack)
    if newnode.name ~= "default:furnace" then
       if  newnode.name ~= "default:furnace_active" then
           return
       end
    end
    pos.y = pos.y+1
    local ent = minetest.env:add_entity(pos, "gauges:furnace_bar")
    pos.y = pos.y-1
    if ent~= nil then
       ent = ent:get_luaentity()
       ent.wielder = pos             
    end
end

And this how I delete an entity:

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

  local position = self.wielder
  if minetest.env:get_node(position).name == "air" then
     self.object:remove()
     return   
  end

i somewhat achieved what i wanted. check out my torch mod.
thank you anyway
