I was thinking about a bigger ship as the attacker's base, but haven't gotten around to that.
How would you go about making the bunker capture-able, and the current captors spawn there, with the defenders the default one.
Doesn't just need a large attackers base, needs more beach my friend.
If you wanted to do the whole 'you capture this you spawn here' deal you could just make a room where you can shoose where you want to spawn. So in the beginning, the attackers only get to choose their ship out in the ocean and the boats in the water. The defenders would get to choose any of the bunkers they wanted.
But once one of the points was captured, you would have an event make a block appear that would be a new selection for the attackers to spawn, and it would take away that block on the defenders spawn room.
