Let's say we have a room with 100 objects. How do we know if any of those 100 objects are touching one another?
|
||
|
|
|
||
|
|
The naive solution is to simply check each pair of objects and see if they are colliding.
|
||
|
|
|
||
|
|
Unfortunately, this will require 10000 comparisons.
|
||
|
|
|
||
|
|
In other words, this naive approach becomes *extremely* expensive as the number of collision objects grows.
|
||
|
|
|
||
|
|
The solution? Broad-phase collision detection.
|
||
|
|
|
||
|
|
The purpose of the broad-phase is to very quickly check if an object *might* be touching another object. Then, once we know that an object might be touching another object, we can do a more expensive and accurate test.

There are a few different ways to do this. The only way that Bonk currently implements is the *spatial hash* technique.
