Redstone (event)

2013-01-13T09:27:30Z

Keeree: Added a second more complete example of usage, and how you might treat this event.

{{NeedsWork|A demonstration on the use and handling of this event would be beneficial. ''[[User:AfterLifeLochie|AfterLifeLochie]] 16:13, 30 November 2012 (MSK)''}}

{{Event
|name=redstone
|desc=Fired when any Redstone inputs change on any of the sides of the computer.
}}=== Basic Usage ===
{{Example
|desc=Alerts via console output when a redstone input changes.
|code=
while true do
event = os.pullEvent("redstone")
print("Redstone input changed.")
end
|output=This will tell one when the redstone event is triggered. Note this doesn't tell you the side of the event.
}}=== Application ===
{{Example
|desc=This program will store the values of each redstone signal on load, and on each state change. It will further display on the screen which state was changed.
|code=
-- Set up a list which contains the sides as keys, and the current redstone state of each side as a boolean value
statelist = {
["top"] = rs.getInput("top"),
["front"] = rs.getInput("front"),
["left"] = rs.getInput("left"),
["right"] = rs.getInput("right"),
["back"] = rs.getInput("back"),
["bottom"] = rs.getInput("bottom"),
}

-- Ready the terminal for printing to
term.clear()
term.setCursorPos(1,1)

while true do -- Start an endless loop
os.pullEvent("redstone") -- Yeild the computer until some redstone changes
-- We don't care what the event returns, since the first variable will be "redstone" and the rest will be nil.

--Now we check each side to see if it's changed.
for side, state in pairs(statelist) do -- Run the lines of code in this loop for each key/value pair in statelist
if rs.getInput(side) ~= state then -- If the side we're checking doesn't match what it was last time we checked then
print(side.." is now "..tostring(rs.getInput(side))) -- Print the new state of the side.
statelist[side] = rs.getInput(side) -- Update the statelist with the new change
end
end
end
}}

Keeree: Adding Example code

Char (event)

2013-01-09T02:27:02Z

Keeree: Added example.

{{NeedsWork|A demonstration on the use and handling of this event would be beneficial. ''[[User:AfterLifeLochie|AfterLifeLochie]] 16:09, 30 November 2012 (MSK)''}}

{{Event
|name=char
|desc=Fired when a alphanumeric key is pressed on the keyboard.
|return1=The [[String_(type)|String]] representing the character that was pressed.
}}
{{Example
|desc=Prints out the character that was pressed.
|code=
while true do
event, character = os.pullEvent("char")
print(character.." was pressed.")
end
|output=The key that was pressed. Note this doesn't trigger for Tab, Shift, the up arrow, etc. Use the [[key_(event)|key]] event if you wish to trap those keys.
}}

Key (event)

2013-01-08T01:05:27Z

Keeree: Codefix.

{{NeedsWork|A demonstration on the use and handling of this event would be beneficial. ''[[User:AfterLifeLochie|AfterLifeLochie]] 16:10, 30 November 2012 (MSK)''}}

{{Event
|name=key
|desc=Fired when any key is pressed while the terminal is focused.
|return1=The numerical key value of the key pressed.
}}
{{Example
|desc=Print each key pressed on the keyboard whenever a ''key'' event is fired. Use Ctrl+T (Windows) to terminate the loop.
|code=
while true do
event, scancode = os.pullEvent("key")
print(tostring(scancode).." was pressed.")
end
|output=Any key that is pressed.
}}
