I’m working through a number of design decisions before I release the next article. This engine started as a personal project, but I decided to use it as the topic of a thesis paper for this semester. However, this puts a severe time constraint on the engine, as the thesis is due on April 25.

The last type of collision we need to implement is the circle-to-rectangle collision. The math behind such a collision is split into two parts based on where the collision is on the rectangle.

While implementing the circle colliders, I decided to do some refactoring of the collision system. Most notably, I’ve added two vectors, resolution and impulse, to keep track of the minimum displacement needed to resolve the collision and the impulse that needs to be applied to the colliding entities.

Before we can safely make our entities move, we need a way to make them stop. To accomplish this goal, the next thing to implement is a collision system. There are a few considerations to make, such as what types of collisions our collision system should support and what shapes we will use.

I’m working on a post to describe the collision system. I’ve implemented a simple rectangle collision, but am adding support for circle collisions as well. I’m also playing around with some options on mass and elasticity. Once I’ve determined all of that, I’ll have a post ready!
