In order to have any sort of gameplay, you need some interactability. The most basic kind is movement, and with it, comes the risk bumping into stuff, a.k.a. collision. Although simple, this was my first practical introduction into vector math and was fundamental for my future projects.

• Implemented basic AABB collision between units and terrain obstacles

• Implemented smooth steering for all units, with different degree of angle sharpness.

During the last week of the project, I developed a simple collision avoidance algorithm, following this article by Andrew Fray.

Using dot products between the destination vector and the green vectors (see gif), and comparing them between the dot products between the obstacle vectors and the green vectors. Then, by multiplying their magnitude by the calculated products, the algorithm chooses the most optimal direction.
