Iterator< Object >	getCheckIterator (Vector2f loc, float checkWidth, float checkHeight)

Detailed Description

Bin-lattice with combat entities - ships, missiles, asteroids, projectiles, beams, etc - sorted into buckets based on their location. May only have a subset of these objects in it, depending on this grid's role.

Used to fulfill "all objects in area" queries without having to iterate through every object.

Occasionally just getting a list of the entities - i.e. via CombatEngineAPI.getShips() may be a bit faster than using the grid. In particular, this will more often be the case when using the grid for a large area. For something very performance intensive, it makes sense to try each way to see which is faster in a given situation.
