So, I tried changing the group number of the flag to that of a submarine...and just as I thought, since its the same group number you cannot choose which point you want to spawn at. Yes it disappears when the other team takes the flag...but thats about it..
I used this way however:
1. Spawn gato / sub7c apart
2. Other team spawns a PT boat (I used it for its REDICULOUS mass), and increased the speedmod of the subs to 100. The PT boats take damage from water.
3. A red PT boat spawns above blue sub location when red has base (50 meters above).
4. A blue PT boat spawns above red sub when blue has base (50 meters).
This works pretty good. I was worried about any lag that might be caused (PT boats falling from the sky fairly often..), but even with the short spawn time, the PT boats were spawning 1050 meters in the air...so there was probably a 6 second free-fall. I can't see what happens, but I'm sure the PT boat WRECKS the sub on the way down, haha.
Anyone know how to do this without stuff falling on other stuff?
