[1.16.1] Help with Line of Sight checks

[FTC55]

Hello, I'm trying to implement some logic in my mod that requires to know wether a given set of coordinates is in line of sight of another, in the sense that a straight line can be traced between the two without it being interrupted by any solid blocks. I first thought of ray tracing but I can't find a useful method that can do this nor any piece of documentation regarding this, could anyone help me with that?

Use IBlockReader.rayTraceBlocks(RayTraceContext) method. It does exactly what you need.

(World implements IBlockReader)

 

Example of usage is at Entity::pick
