[Tutorial] 2D grid spatial partitioning basics (speed up collision broad-phase)

[sorry for the audio issues!] A grid as a spatial partitioning method is easy to implement and can speed up immensely collision detection. In this video, I try to explain how it works, how bodies do not have to match the cell size, and a possible implementation. Check out my implementation at: The code examples shown in the video are made exclusively for illustrative purposes - they help the viewer under
