A vector is something that has direction and magnitude.

Implemented in: UnityEngine. Thank you for helping us improve the quality of Unity Documentation. Although we cannot accept all submissions, we do read each suggested change from our users and will make updates where applicable. For some reason your suggested change could not be submitted. And thank you for taking the time to help us improve the quality of Unity Documentation. This structure is used throughout Unity to pass 3D positions and directions around. It also contains functions for doing common vector operations.

By default, a Vector3 takes float as input.

Vectors are a fundamental mathematical concept which allow you to describe a direction and magnitude. In games and apps, vectors are often used to describe some of the fundamental properties such as the position of a character, the speed something is moving, or the distance between two objects. Vector arithmetic is fundamental to many aspects of computer programming such as graphics, physics and animation, and it is useful to understand it in depth to get the most out of Unity. Vectors can be expressed in multiple dimensions, and Unity provides the Vector2, Vector3 and Vector4 classes for working with 2D, 3D, and 4D vectors. These three types of Vector classes all share many of the same functions, such as magnitude, so most of the information on this page applies to all three types of Vector unless otherwise specified. This page provides an overview of the Vector classes and their common uses when scripting with them. For an exhaustive reference of every member of the vector classes, see the script reference pages for Vector2 , Vector3 and Vector4. For example, to find a point 5 units above a location on the ground, you could use the following calculation If the vectors represent forces then it is more intuitive to think of them in terms of their direction and magnitude the magnitude indicates the size of the force. Adding two force vectors results in a new vector equivalent to the combination of the forces.

A Vector3 structure can be created in several ways. Vector3 is a struct, and as such, will typically need to be instantiated before use. While rare, you may run into situations where you would need to treat the co-ordinates of a Vector2 or Vector4 structure as a Vector3. In such cases, you can simply pass the Vector2 or Vector4 directly into the Vector3 , without previously instantiating it. As should be assumed, a Vector2 struct will only pass x and y values, while a Vector4 class will omit its w.

Position of any Gameobject. Operators operator - Subtracts one vector from another. Distance Returns the distance between a and b. OrthoNormalize Makes vectors normalized and orthogonal to each other. ProjectOnPlane Projects a vector onto a plane defined by a normal orthogonal to the plane. By default, a Vector3 takes float as input. Slerp Spherically interpolates between two vectors. Project will project the provided vector onto the normal vector. In this tutorial, we will see how to use Vector3 to its maximum potential. ToString Returns a formatted string for this vector. A three-Dimensional vector is called Vector3. Move Gameobject by one unity using transform.

A normal vector is a Unit vector representing the direction of the vector. Cross Cross Product of two vectors. Slowly move towards a point in steps of 1. Slowly Look towards an Enemy. Shorthand for writing Vector3 float. If you do not require the precision of float then you can specify the input as integer in the manner shown below. Description Representation of 3D vectors and points. Dot Dot Product of two vectors. In this tutorial, we will see how to use Vector3 to its maximum potential. Max Returns a vector that is made from the largest components of two vectors. SmoothDamp Gradually changes a vector towards a desired goal over time.
