I asked ChatGPT 4 to use Codea’s objc to authenticate the player inside Codea. Here’s the code it gave me:
AuthenticationHandler = objc.class("AuthenticationHandler")
function AuthenticationHandler:authenticateLocalPlayer()
-- Obtain GKLocalPlayer from GameKit
local GKLocalPlayer = objc.GKLocalPlayer:localPlayer()
-- Define a block to handle authentication response
local authResponseBlock = objc.block(function(authViewController, error)
if authViewController then
-- Present the authentication view controller
print("Present the authentication view controller")
elseif GKLocalPlayer:isAuthenticated() then
print("Player authenticated")
else
print("Player not authenticated:", error)
end
end, "v@?@") -- v@?@ is the block signature for this block
-- Set the authenticate handler
GKLocalPlayer:setAuthenticateHandler_(authResponseBlock)
end
local authHandler = AuthenticationHandler()
authHandler:authenticateLocalPlayer()
It doesn’t work because GKLocalPlayer isn’t available from objc. Would it work if it was?
