--=================================================
|
|
--
|
|
--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
|
|
--e.g. if you want to use the "pressureplate" rules, you use this command:
|
|
--mesecon:receptor_on (pos, mesecon:get_rules("pressureplate"))
|
|
--The rules can be manipulated by several rotate functions:
|
|
--rules=mesecon:rotate_rules_right/left/up/down(rules)
|
|
--
|
|
--
|
|
--
|
|
--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
|
|
--
|
|
--CONDUCTORS: (new feature!! yay)
|
|
--You can specify your custom conductors using
|
|
--# mesecon:register_conductor(onstate, offstate)
|
|
-- onstate=the conductor's nodename when it is turned on
|
|
-- offstate=the conductor's nodename when it is turned off
|
|
--
|
|
--As you can see, conductors need an offstate and an onstate node, just like receptors
|
|
--mesecons:mesecon_on / mesecons:mesecon_off are the default conductors
|
|
--Other conductors connect to other conductors. It's always "the same energy"
|
|
--! As there is no special drawtype, conductors don't connect to others visually,
|
|
--but it works in fact.
|
|
--
|
|
--The function # mesecon:register_conductor(onstate, offstate) is the only thing you need to do,
|
|
--the mod does everything else for you (turn the conductor on and off...)
