I managed to get pathfinding work for a single unit, and I managed to avoid agent-agent collision, but now I need to be able to send a group of agents to some location.
This is my set-up so far:
- waypoint pathfinding
- the minimum distance between two nodes is a little bigger than the biggest bounding sphere radius allowed for an agent.
- agent avoid collisions with other agents by doing some steering behaviour I based on clearpath (http://www.youtube.com/watch?v=Hc6kng5A8lQ)
So now I need to send my agents somewhere in group. I have read some posts saying that some way to do it is to create a group leader and give the other units offsets to his position.
But then the problem is, what if the group formation cannot be achieved? eg you want to form a rectangle, but at the target position there is a structure nearby which prevents you from creating a rectangle setup.
