public Vector3 up ;

설명

The green axis of the transform in world space.

Manipulate a GameObject’s position on the Y axis (green axis) of the transform in world space. Unlike Vector3.up, Transform.up moves the GameObject while also considering its rotation.

When a GameObject is rotated, the green arrow representing the Y axis of the GameObject also changes direction. Transform.up moves the GameObject in the green arrow’s axis (Y).

For moving the GameObject on the Y axis while ignoring rotation, see Vector3.up.

using UnityEngine;

public class Example : MonoBehaviour { Rigidbody2D m_Rigidbody; float m_Speed;

void Start() { //Fetch the Rigidbody component you attach from your GameObject m_Rigidbody = GetComponent<Rigidbody2D>(); //Set the speed of the GameObject m_Speed = 10.0f; }

void Update() { if (Input.GetKey(KeyCode.UpArrow)) { //Move the Rigidbody upwards constantly at speed you define (the green arrow axis in Scene view) m_Rigidbody.velocity = transform.up * m_Speed; }

if (Input.GetKey(KeyCode.DownArrow)) { //Move the Rigidbody downwards constantly at the speed you define (the green arrow axis in Scene view) m_Rigidbody.velocity = -transform.up * m_Speed; }

if (Input.GetKey(KeyCode.LeftArrow)) { //rotate the sprite about the Z axis in the positive direction transform.Rotate(new Vector3(0, 0, 1) * Time.deltaTime * m_Speed, Space.World); }

if (Input.GetKey(KeyCode.RightArrow)) { //rotate the sprite about the Z axis in the negative direction transform.Rotate(new Vector3(0, 0, -1) * Time.deltaTime * m_Speed, Space.World); } } }
