The [`task_complete`] event is fired when an asynchronous task completes. This is usually handled inside the function call that queued the task; however, functions such as [`commands.execAsync`] return immediately so the user can wait for completion.
|
|
|
|
## Return Values
|
|
1. [`string`]: The event name.
|
|
2. [`number`]: The ID of the task that completed.
|
|
3. [`boolean`]: Whether the command succeeded.
|
|
4. [`string`]: If the command failed, an error message explaining the failure. (This is not present if the command succeeded.)
|
|
5. <abbr title="Variable number of arguments">…</abbr>: Any parameters returned from the command.
|
|
|
|
## Example
|
|
Prints the results of an asynchronous command:
|
|
```lua
|
|
local taskID = commands.execAsync("say Hello")
|
|
local event
|
|
repeat
|
|
event = {os.pullEvent("task_complete")}
|
|
until event[2] == taskID
|
|
if event[3] == true then
|
|
print("Task " .. event[2] .. " succeeded:", table.unpack(event, 4))
|
|
else
|
|
print("Task " .. event[2] .. " failed: " .. event[4])
|
|
end
|
|
```
