Variables

[Drakath]

local lPlayer = localPlayer

What is more efficient?

1. Use lPlayer over 10 times

2. Use localPlayer 10 times?

Practically the same thing, just use localPlayer since it's predefined and everyone knows it.

Numbers, strings, booleans and nil are passed by value, you basically have 2 variables that are equal but do not affect each other. It's fine if you don't get what I mean here, you can read more about it here: http://www.lua.org/manual/5.1/manual.html#2.2

I always do something like

local LOCALPLAYER = localPlayer 

just because my text editor highlights uppercase variables with bold black colour. I don't think there is any other use of that.

But I mean if I use the local lPlayer, system will store it and use the memory. If I use localPlayer, system will check for local player and use CPU. Am I right?

No. When the script starts localPlayer is a 'userdata' that points to the local player. When you define lPlayer, it's now a 'userdata' variable that points to the local player.

Before localPlayer variable was predefined, most people did this at the start of their client scripts:

localPlayer = getLocalPlayer() 

See, the "system" doesn't need to check for the local player, as the local player will never change. Client scripts run on the client, so localPlayer doesn't change, there's no "looking" involved.

I see, thanks.
