 Function parallel.waitForAll | |
| Lets you run multiple functions at the same time, alternating between them until all have finished. Note that it takes function names as parameters (eg "function1", "function2", etc), as opposed to function calls (eg "function1()", "function2()", etc). | |
| Syntax | parallel.waitForAll(function function1, function function2, ...) |
| Returns | None |
| Part of | ComputerCraft |
| API | parallel |
Examples
 Example | |
| Tells the computer to run function1 and function2 at the same time. Will broadcast what the user enters and prints what it receives over rednet. It will stop when it has received a message and the user has entered something. | |
| Code |
local function receive () -- Define the first function. print(rednet.receive()) end local function send () -- Define the second function. rednet.broadcast(read()) end parallel.waitForAll(receive, send) -- Run both functions in parallel and wait until both of them completes. |
| Output | Prints what it received via rednet and broadcasts the message the user typed. |
