--Whiskers75's code
--AND block

-- Make the block:

minetest.register_node ("mesecons_whiskers75:andblock", {
    drawtype = signlike,
    description = "AND block",
    tile_images = {"whiskers75andblock.png"},
    inventory_image = {"whiskers75andblock.png"},
    sunlight_propagates = true,
    paramtype = 'light',
    walkable = true,
    groups = {dig_immediate=2},
    material = minetest.digprop_constanttime(1.0),
   })

local update = function(pos)
	local node = minetest.env:get_node(pos)
	if node.name=="mesecons_whiskers75:andblock" then
		lnode = minetest.env:get_node({x=pos.x-1, y=pos.y, z=pos.z})
		if lnode.name=="mesecons:mesecon_on" then set_node_on({x=pos.x, y=pos.y+1, z=pos.z}) end
		lnode = minetest.env:get_node({x=pos.x+1, y=pos.y, z=pos.z})
		if lnode.name=="mesecons:mesecon_on" then set_node_on({x=pos.x, y=pos.y+1, z=pos.z}) end
	end
end
-- This SHOULD detect mesecons on x+ or -1 and turn a node y+1 on...
