| Description | Subtracts x, y, and z components from a vector, subtracts one vector from another, or subtracts two independent vectors. The version of the method that substracts two vectors is a static method and returns a PVector, the others have no return value -- they act directly on the vector. See the examples for more context. | ||||||||||||||||
| Syntax | vec.sub(x, y, z) vec.sub(v) PVector.sub(v1, v2) | ||||||||||||||||
