coroutine.yield() is a function used in Lua programming language for pausing the execution of a coroutine and returning control to the caller. Coroutines allow you to write non-blocking code, enabling cooperative multitasking by yielding control back and forth between functions.
Here’s a simple example of how coroutine.yield() works:
-- Define a coroutine function
function count()
for i = 1, 5 do
print("Counting: " .. i)
coroutine.yield() -- Pause the coroutine here
end
end
-- Create a new coroutine
co = coroutine.create(count)
-- Resume the coroutine multiple times
for i = 1, 5 do
print("Resuming Coroutine...")
coroutine.resume(co) -- This will execute until it hits yield()
end
Explanation:
- In this example, we define a coroutine function
countthat counts from 1 to 5. - Each time it prints a number, it calls
coroutine.yield(), which pauses its execution. - We then create a coroutine with
coroutine.create()and usecoroutine.resume()to start or continue its execution.
Each call to resume will continue the execution until it reaches the next yield.
