Description


The Sparse Grid Plugin is a high-performance spatial sorting system for Unreal Engine 4, allowing developers to perform ultra-fast queries for objects without the need to use collision tests or iterators.

Forum Thread

The plugin quickly and seamlessly integrates into any C++ or BP project. Use the editor tool to define the play-area of your level (or update it on-the-fly), and add the Sparse Grid Component to any object you wish to register with the system. It's as easy as that!

You can then use the built-in search queries (or create your own), to query those objects very quickly. The system is fully exposed to blueprint, so no C++ knowledge is required to implement.

Common Use-Cases Include:

  • AI bot searching for an enemy.
  • Swarms of homing projectiles searching for targets individually.
  • A radar pinging local objects.
  • Applying damage to a wide range of objects.
  • Testing against players for local-area VOIP.
  • And so on...


Greatly Benefits the following:

  • Games with large/open worlds.
  • Games with high density/number of actors (RTS, Battle Royale etc.)
  • Games with complex or large numbers of AI.
  • Games requiring unique or highly modified collision settings.

Technical Details
