-- This mod adds mesecons[=minecraft redstone] and different receptors/effectors to minetest.
--
-- See the documentation on the forum for additional information, especially about crafting
--
--Quick Developer documentation for the mesecon API
--=================================================
--
--RECEPTORS
--
--A receptor is a node that emits power, e.g. a solar panel, a switch or a power plant.
--Usually you create two blocks per receptor that have to be switched when switching the on/off state:
-- # An off-state node (e.g. mesecons:mesecon_switch_off"
-- # An on-state node (e.g. mesecons:mesecon_switch_on"
--The on-state and off-state nodes should be registered in the mesecon api,
--so that the Mesecon circuit can be recalculated. This can be done using
--
--mesecon:add_receptor_node(nodename) -- for on-state node
--mesecon:add_receptor_node_off(nodename) -- for off-state node
--example: mesecon:add_receptor_node("mesecons:mesecon_switch_on")
--
--Turning receptors on and off
--Usually the receptor has to turn on and off. For this, you have to
-- # Remove the node and replace it with the node in the other state (e.g. replace on by off)
-- # Send the event to the mesecon circuit by using the api functions
-- mesecon:receptor_on (pos, rules) } These functions take the position of your receptor
-- mesecon:receptor_off(pos, rules) } as their parameter.
--
--You can specify the rules using the rules parameter. If you don't want special rules, just leave it out
--
--!! If a receptor node is removed, the circuit should be recalculated. This means you have to
--send an mesecon:receptor_off signal to the api when the function in minetest.register_on_dignode
--is called.
--
--EFFECTORS
--
--A receptor is a node that uses power and transfers the signal to a mechanical, optical whatever
--event. e.g. the meselamp, the movestone or the removestone.
--
--There are two callback functions for receptors.
-- # function mesecon:register_on_signal_on (action)
-- # function mesecon:register_on_signal_off(action)
--
--These functions will be called for each block next to a mesecon conductor.
--
--Example: The removestone
--The removestone only uses one callback: The mesecon:register_on_signal_on function
--
--mesecon:register_on_signal_on(function(pos, node) -- As the action prameter you have to use a function
-- if node.name=="mesecons:removestone" then -- Check if it really is removestone. If you wouldn't use this, every node next to mesecons would be removed
-- minetest.env:remove_node(pos) -- The action: The removestone is removed
-- end -- end of if
--end) -- end of the function, )=end of the parameters of mesecon:register_on_signal_on
-- INCLUDE SETTINGS
