The setPlayerController native AI script function allows a player to control a specific bot in the NPC group.
()setPlayerController(botId: s, playerId: s) // setPlayerController_ss_
()setPlayerController("(0x0002015bb4:01:88:88)", "(0x0000004880:00:00:00)");
This example code allows the player with entity ID "(0x0000004880:00:00:00)" to control the bot with entity ID "(0x0002015bb4:01:88:88)".
