Roblox 通過引入 task 庫更新了處理異步任務的最佳實踐。與較早的 spawn、delay 和 wait 函數相比，task 庫提供了一種更簡潔、更高效的方式來處理後台任務。task 庫包括 task.spawn, task.delay 和 task.wait 等方法，旨在更可靠並提供更好的性能。
| 操作 | 詳情 |
|---|---|
| task.spawn | task.spawn 用於異步運行函數而不阻塞調用者。 |
| task.delay | task.delay 用於在指定的延遲後執行函數，允許創建定時或延遲的操作而不阻塞其他操作。 |
| task.wait | task.wait 用於暫停當前任務指定的時間段。 |
task.spawn
local function doBackgroundTask()
print("Background task started")
for i = 1, 10 do
print("Processing step " .. i)
wait(1) -- Simulate some processing delay
end
print("Background task completed")
end
print("Main script execution")
task.spawn(doBackgroundTask)
print("Main script continues immediately after launching background task")
Roblox Studio
task.delay
local function delayedTask()
print("Delayed task executed after 5 seconds")
end
print("Main script execution")
task.delay(5, delayedTask) -- Delay execution of delayedTask by 5 seconds
print("Main script continues immediately after scheduling delayed task")
Roblox Studio
task.wait
local function waitForSomeTime()
print("Wait starting")
task.wait(5) -- Pauses this function, not the entire script, for 5 seconds
print("Wait ended after 5 seconds")
end
print("Main script execution")
task.spawn(waitForSomeTime)
print("Main script continues immediately, while waitForSomeTime pauses internally")
