What do people think would be the best way to implement an entity based pathfinding system+unit spacing? Currently I only have simple movement (click on ground, translate to point), and then all my units condense into a single point like a horrifying singularity. And then my framerate crashes when they all shoot from the same position. I don't know if a navMesh and navAgents are performent with entities, or how to implement them. So, any ideas, suggestions, resource links, or miscellaneous information/ opinions?
