I want to make a gate on a castle just like on the Helms Deep map. One that the player can open and close, but that doesn't reset to max HP or resurrect every time they open and close it. How can I do that? If I make a gate and hook it up to a lever with triggers, it'll open and close just fine. But as soon as the gate takes damage, or even if it's destroyed, the player just has to open and close it again and it's back to full health.
