CanChangeCode

OxideCarbonPlayer

Called to determine whether to change code.

Return true to allow the action and false to block it.

object CanChangeCode(BasePlayer player, CodeLock codeLock, string local0, bool local1)

Works — the game method in this build is the one the hook was written for.

Parameters

player: BasePlayer
codeLock: CodeLock
local0: string
local1: bool

Return value

objectReturn non-null to cancel the game action.

Example

object — you can affect the game: return a value to change or cancel the action.

private object CanChangeCode(BasePlayer player, CodeLock codeLock, string local0, bool local1)
{
    Puts("CanChangeCode");

    // change nothing — the game continues as usual
    return null;

    // to affect the game:
    // return false; // non-null cancels the game action
}

Works in both Oxide and Carbon: Carbon loads Oxide plugins as is.
