help interigating with mesecons

PostPosted: Mon Nov 26, 2012 16:12

I am trying to write a mod which will interigate with the mesecons mod. I can get my mod to recognize the mesecons and turn on and off with them, but when i try and connect a messecon to my mod, the new mesecon will not recognize that it is connected to a powered node.

I know that my code is not the cleanest and probably a lot of bugs and better ways to accomplish the same thing, but any information on what I am doing wrong is greatly apreaciated.

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
-- sl_base

VERSION = "0.0.1"

minetest.register_node("sl_base:concrete_off", {
    drawtype = "normal",
    description = "Street Lamp - Concrete Base",
    tiles = sl_tiles.concrete_off,
    groups = {cracky=3, mesecon=3},
   
     after_place_node = function(pos, placer)
        local node = minetest.env:get_node(pos)
        if sl_check_power(pos, mesecon:get_rules(node.name)) then
            minetest.env:add_node(pos, {name="sl_base:concrete_on"})
            mesecon:turnon(pos)
        end
--          local node = minetest.env:get_node(pos)
--          local rules = mesecon:conductor_get_rules(node)
--         print(node.name)
--          for i, rule in ipairs(rules) do
--              local np = {}
--              np.x = pos.x + rule.x
--              np.y = pos.y + rule.y
--              np.z = pos.z + rule.z
--             local n = minetest.env:get_node(np)
-- --            if mesecon:is_receptor
-- --            if mesecon:is_powered(np) then
--             if mesecon:connected_to_pw_src(np) then
--                 mesecon:turnon(pos)
--                 nodeupdate(pos)
--                 mesecon:receptor_on(pos)
--             end
--          end
     end,
   
    after_dig_node = function(pos, oldnode, oldmetadata, digger)
    end,
       
})

minetest.register_node("sl_base:concrete_on", {
    drawtype = "normal",
    description = "Street Lamp - Concrete Base",
    tiles = sl_tiles.concrete_on,
    groups = {cracky=3, mesecon=3, not_in_creative_inventory=1},
    drop = "sl_base:concrete_off",
   
    after_dig_node = function(pos, oldnode, oldmetadata, digger)
        local node = minetest.env:get_node(pos)
        local rules = mesecon:get_rules("sl_base:concrete_on")

            local np = {}
            np.x = pos.x + rule.x
            np.y = pos.y + rule.y
            np.z = pos.z + rule.z
            local name = minetest.env:get_node(np).name
            print("here i am "..name)
            if name ~= "air" and not sl_check_power(np, mesecon:get_rules(name)) then
                if not mesecon:connected_to_pw_src(np) then
                    mesecon:turnoff(np)
                end
            end
        end
    end,
})
   
mesecon:register_conductor("sl_base:concrete_on", "sl_base:concrete_off", mesecon:get_rules("sl_base:concrete_off"))

print("[Street Lamp] -- sl_base -- loaded.  Version: "..VERSION)

does no one know what I am doing wrong? I sure could use some help on this

Please be patient. If no one responded, it's not because they don't care; it's because no one has the answer yet. If someone did, he or she would gladly help you. Thanks for understanding.

There is no clue of what is going wrong in in your ./minetest/debug.txt ?

I will help you. I assume you are trying to conduct mesecons from concrete_base block to the top of a street lamp, and turn it on when mesecon signal is applied. Mesecons has a few operations for signal reaction.
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 swap_node = function(pos, name)
    local node = minetest.env:get_node(pos)
    local data = minetest.env:get_meta(pos):to_table()
    node.name = name
    minetest.env:add_node(pos, node)
    minetest.env:get_meta(pos):from_table(data)
end
(the swap node function)


mesecon:register_on_signal_on(function(pos, node)
    if node.name ~= "sl_base:concrete_off" then
        return
    end

    swap_node(pos, "sl_base:concrete_on")

end)
(if mesecons is on, make it on)

mesecon:register_on_signal_off(function(pos, node)
    if node.name == "sl_base:concrete_on" then
        swap_node(pos, "sl_base:concrete_off")
    end
(If mesecons is off, then make it off.)

minetest.register_abm({
     frequency = 1,
     chance = 1,
     nodenames = {street_lamps:streetlamp_off}, (switch with actual name)
     (other variables here)
     action = function(pos)
          if minetest.env:get_node({x=pos.x, y=pos.y-1, z = pos.z-1}).name() == "sl_base:concrete_on" then
                    minetest.env:set_node(pos, {name="lamp_on"}) (I think that is how you set_node lol)
          end
end,
})
minetest.register_abm({
     frequency = 1,
     chance = 1,
     nodenames = {street_lamps:streetlamp_on}, (switch with actual name)
     (other variables here)
     action = function(pos)
          if minetest.env:get_node({x=pos.x, y=pos.y-1, z = pos.z-1}).name() == "sl_base:concrete_off" then
                    minetest.env:set_node(pos, {name="lamp_off"}) (I think that is how you set_node lol)
          end
end,
})


This registers an abm that changes the streetlamp segment to on if the block under it is concrete_on. Just copy and paste it to make it off, etc.

Hope it helps :)
