nil

Description

There is no C NULL macro. Compare with !=. guard (player != null) is the usual early-out.

Uninitialized locals (int coins;) also emit nil — always initialize.

Example

Player playerRef = null;
guard (playerRef != null) else {
    return;
}

Emits:

local playerRef: Player = nil
if not (playerRef ~= nil) then
  return
end
