Create file ”edit bc” Paste this custom API
local tCableState = {} -- Holds the state of all bundled cables on the computer.
-- Get the current state for all 6 sides.
for _, v in pairs( rs.getSides() ) do
tCableState[ v ] = rs.getBundledInput( v )
end
-- If a bundled cable changes its state, then this function returns the event 'bundled_cable' and a table.
-- The returned table contains only sides that have changed and it has this format: { side = { new_value, old_value } }
function pullEvent()
local bStatesChanged = false
local tChangedCables = {}
local event, p1, p2, p3, p4, p5 = os.pullEvent()
if event == "redstone" then
-- Iterate over all 6 sides of the computer.
for _, v in pairs( rs.getSides() ) do
local nBCInput = rs.getBundledInput( v ) -- Get cable input for current side.
if nBCInput ~= tCableState[ v ] then -- Has the state changed?
tChangedCables[ v ] = { nBCInput, tCableState[ v ] } -- Add the changed side + its new and old values to the return table.
tCableState[ v ] = nBCInput -- Update the local state table.
bStatesChanged = true
end
end
end
-- Turn the 'redstone' event into a 'bundled_cable' event if the state of a bundled cable has changed.
if bStatesChanged then
event = "bundled_cable"
p1 = tChangedCables
end
return event, p1, p2, p3, p4, p5
endand activate it by creating new filee ”edit core” with
-- Load API
if not os.loadAPI( "bc" ) then
error( "Bundled-Cable Event API could not be loaded. :unsure:/>/>" )
end
while true do
local sEvent, p1, p2, p3, p4, p5 = bc.pullEvent() -- Here we call our customized event listener bc.pullEvent(), instead of os.pullEvent()
if sEvent == "bundled_cable" then
-- p1 will contain a table with all the sides that have changed, mapped to their new and old values, i.e. p1 := { "side" = { new_value, old_value } }
local new = 1
local old = 2
for side, tValue in pairs( p1 ) do
print( "\""..side.."\" has changed from "..tValue[ old ].." to "..tValue[ new ] )
