wrap()

The wrap() function makes a coroutine and gives back a function. When that function is called, it resumes the coroutine.

Syntax

coroutine.wrap(function)

• wrap() is a function in Lua that creates a coroutine and returns a function that, when called, resumes the coroutine.
• It is similar to coroutine.create(), but instead of returning the coroutine itself, it returns a function that can be called multiple times to resume the coroutine.

Example

This example utilizes the wrap() function to execute a wrapped coroutine, printing a specific message.

function myCoroutine()
  print("Hello from coroutine wrap!")
end

local wrappedCoroutine = coroutine.wrap(myCoroutine)
wrappedCoroutine()

This will output:

Hello from coroutine wrap!
