Working with time in Lua?

Question

Lua

How can you perform an action in Lua on time? For example, the first line of code is executed, then we wait 3 seconds and execute further according to the algorithm.
How to implement this?

Answer 1

sleep

Answer 2

Depends on what time management tools are provided by the runtime (that is, the parent application where Lua is embedded).
For example, if the parent application constantly calls the global Update() function, and the os.time() function is also available, then you can detect the time at the very beginning, and then periodically read it again inside Update(). Each time we compare the new time with the initial one. As soon as the difference is more than 3 seconds, then it's time to move on. Something like this.
