I am looking for a tutorial or an explanation what these vectors do.

They don't really do anything themselves, they're just vectors.that store 2 or more coordinates and provide methods for various vector operations (e.g. addition, subtraction, normalisation, dot and cross product).

 

The number in the name is how many coordinates the vector stores (i.e. the number of dimensions). The letter after the number is the numerical data type used by the vector, e.g. i for int, d for double, f for float.

Another question, why was vec3 removed in 1.10.2?

It was renamed to Vec3d in 1.9 for consistency with the other vector class names.

Another question, what is the best substitute from create vector helper, you see, I am helping the Dragon Mounts Author fix the player's position while riding the dragon, but in 1.10 they removed UpdateRiderPostion method in the Entity.class, the author and many of his helpers struggle to fix the bug.

Vec3.createVectorHelper was removed in 1.8 when the Vec3 constructor was made public. Just use the constructor directly.

thanks a lot man!

helpful tip use variables

 

Vec3d vecPoint = new Vec3d(fill up 3 paramaters here);
