[SCRIPT] Lights ON and OFF

[Your Computer]

I still don't understand somehow

Do I need to change my void MyFunc
Or is SetEntityConnectionStateChangeCallback works different ?

I fell like a retard :/

The second argument of SetEntityConnectionStateChangeCallback is the name of the function that is to be the callback set for the entity provided in the first argument. Did you pass in "MyFunc" to the second argument? No, you passed in "lights_on". However, the syntax for the callback function requires two parameters: one of type string and one of type int. Your current lights_on function only declares one parameter, which is of type string.
