Real use of resident 0 script?

[rbourgeon]

A key feature of the resident scripts with 0 second pause is that their global variables are memorized from one execution to the next one. Knowing this, if we want to have a script that always does the same thing over and over, we have two options:

Option 1 - Each execution of the script terminates and then passes the values of the global variables to the next execution

Code:

if MY_SCRIPT == nil then   -- initialization   MY_SCRIPT = {}   MY_SCRIPT.foo1 = value1   MY_SCRIPT.foo2 = value2   MY_SCRIPT.loop = function()     -- do some stuff   end end MY_SCRIPT.loop() -- one loop execution runs, then the script ends, -- and because it's a resident 0, it will restart itself -- immediately, with the variable MY_SCRIPT still in memory, -- so the loop function will run again

Option 2 - There is only one execution of the script, it runs forever

Code:

-- initialization MY_SCRIPT = {} MY_SCRIPT.foo1 = value1 MY_SCRIPT.foo2 = value2 MY_SCRIPT.loop = function()   -- do some stuff end -- we loop forever, so it's always the same instance of the script running while true do   MY_SCRIPT.loop() end

Can you explain to me which of the two options is the most efficient and the most CPU-friendly, and tell me why?

The second option is a tiny bit better but it does not really matter.

Previously "while true" loops were prohibited in resident scripts, because scripts were reloaded on the fly after saving changes. Now scripts are fully restarted so infinite loops are allowed.
