Game Command for target player

Description

This code adds a green chat message to the chat box for all players, showing the name of the game that a specified player is playing, when typing /game player.
If the specified player is not found, an orange chat message is shown to only the player that typed the command.

Code

	if not client2 then
		messageClient('Player not found', client, COLOUR_ORANGE)
	else
		message(client2.player.name .. ' is playing ' .. getGameNameFromGameId(client2.game), COLOUR_GREEN)
	end
end)
