Can someone help me with some Portal 1 mapping work? I want to ask some questions: 1. How do I place the energy orb launchers and catchers into my map? 2. How do I place fizzlers, automatic doors, elevators, buttons and all of that? 3. (Not specifically a portal-related question but oh well) How do I make an NPC play an animation as soon as the map starts? Do I need logic_auto for that?
