That's basic vector arithmetic notions. The web is full of resources about this.

Unity has implemented the following function to find what you want : Vector3.Project

"That's basic vector arithmetic notions. The web is full of resources about this." Yes I understand the arithmetic, just wanted to know if Unity already had this implemented. Thanks.
