Unity Script Reference – Transform.LookAt

Transform.LookAt

function LookAt (target : Transform, worldUp : Vector3 = Vector3.up) : void

Description

Rotates the transform so the forward vector points at /target/'s current position.

Then it rotates the transform to point its up direction vector in the direction hinted at by the worldUp vector. If you leave out the worldUp parameter, the function will use the world y axis. worldUp is only a hint vector. The up vector of the rotation will only match the worldUp vector if the forward direction is perpendicular to worldUp

JavaScripts

// This complete script can be attached to a camera to make it
// continuously point at another object.

// The target variable shows up as a property in the inspector.
// Drag another object onto it to make the camera look at it.
var target : Transform;

// Rotate the camera every frame so it keeps looking at the target
function Update() {
transform.LookAt(target);
}

function LookAt (worldPosition : Vector3, worldUp : Vector3 = Vector3.up) : void

Description
