The SetLookAtRotationMatrix method can be used to orient a camera so it is facing an object. This method of setting the rotation matrix can be easier to work with than calculating a rotation matrix yourself to accomplish a look-at.

Code Example

The following code can be used to have a Camera look at a moving object called myEntity. This code assumes that myEntity is a valid Entity with a Position property.

Camera cameraToUse = SpriteManager.Camera;
Vector3 positionToLookAt = myEntity.Position;
