Ray picking

[rsachetto]

Hello everyone.

I am writing a visualizer for the simulator that I work on and I am having some problems to implement the selection of an object (in my case, I want to select a cube).

My simulator output is a mesh made of cubes. I draw the mesh on the screen by drawing each cube individually (I know this is not the best way, and I will try to optimize it later). My problem is the following:

To select a cube, I am using GetRayCollisionBox. The Ray comes from the function GetMouseRay. The problem is that the ray can hit multiple cubes (as showing in the figure below).

My question is: how can I know what cube was really clicked? Is there a better way to do this witout using ray picking?

OffBrandLaw and JeffM helped me on raylib's discord. In order to solve the problem I had to keep track of the ray collision with the smallest distance.
