I was thinking of trying to simulate a bridge that slides out from the wall in the last stage of Invasion. I created 7 small bridge objects (obviously this would be a little clunky but I thought it would work), and I set them all to INV_WEAPON and spawn stage 3. Then I set their spawn timers to 1, 2, 3, 4, 5, 6, and 7 (in the order in which the bridge would work). However, they kind of seem to spawn haphazardly; both ends of the bridge spawn before the middle spawns. I double-checked my settings and I am pretty sure I have all of the configurations how they should be. Is this something that I can do with Forge in another way?
I had seen this in another bridge months ago. I checked their settings and saw exactly the same thing. Never knew what to make of it...
I'm pretty sure it's a glitch. I've messed around with this and it doesn't seem that you're able to make items spawn as timed in Invasion using INV_WEAPON tags. It may look odd, but despite which pieces spawn first you do end with a complete bridge.
All i can think of is using Invasion_Vehicle over weapon. Give that a shot, see how it will work. Also, try turning spawn at start to off. This gave me a better result.
