Transform.position 유니티 예제

using System.Collections; using System.Collections.Generic; using UnityEngine; // Transform.position example. // // Animate a sphere around a circle and bounce up and down. public class ExampleScript : MonoBehaviour { private Vector3 spherePosition; private float xzPosition, yPosition; private float increaseXZPosition, increaseYPosition; void Awake() { // Three seconds per circular rotation. increaseXZPosition = (2.0f * Mathf.PI) / 3.0f; // Random speed up/down. increaseYPosition = (2.0f * Mathf.PI) / 1.3f; // Create a floor for the sphere to bounce on. GameObject quad; quad = GameObject.CreatePrimitive(PrimitiveType.Quad); quad.transform.rotation = Quaternion.Euler(90, 0, 0); quad.transform.localScale = new Vector3(8, 8, 1); // Sphere is 1 unit in size. Drop floor by half this. quad.transform.position = new Vector3(0.0f, -0.5f, 0.0f); // Change the camera position and rotation. Camera.main.transform.position = new Vector3(2.5f, 7.5f, 0.8f); Camera.main.transform.rotation = Quaternion.Euler(65, -105, 0); } void Update() { // Move sphere around the circle. spherePosition = new Vector3(2.0f * Mathf.Sin(xzPosition), 4.0f * Mathf.Sin(yPosition), 2.0f * Mathf.Cos(xzPosition)); transform.position = spherePosition; // Update the rotating position. xzPosition += increaseXZPosition * Time.deltaTime; if (xzPosition > 2.0f * Mathf.PI) { xzPosition = xzPosition - 2.0f * Mathf.PI; } // Update the up/down position. yPosition += increaseYPosition * Time.deltaTime; if (yPosition > Mathf.PI) { yPosition = yPosition - Mathf.PI; } } // Display the changing position of the sphere. void OnGUI() { GUIStyle fontSize = new GUIStyle(GUI.skin.GetStyle("label")); fontSize.fontSize = 24; GUI.Label(new Rect(20, 20, 300, 50), "Position: " + spherePosition.ToString("F2"), fontSize); } }

1. GameObject의 위치를 직접 지정하는 방법

using System.Collections; transform.position = new Vector3(x, y, z);

2. Translate로 이동하는 방법

Vector3 dir = target.position - transform.position; transform.Translate(dir.normalized * speed * Time.deltaTime, Space.World);

3. Target 오브젝트를 향해 일정하게 이동하는 방법

// The step size is equal to speed times frame time. float step = speed * Time.deltaTime; // Move our position a step closer to the target. transform.position = Vector3.MoveTowards(transform.position, target.position, step);

4. Rigidbody의 AddForce를 사용하여 이동하는 방법

using UnityEngine; public class ExampleClass : MonoBehaviour { public float thrust; public Rigidbody rb; void Start() { rb = GetComponent<Rigidbody>(); } void FixedUpdate() { rb.AddForce(transform.forward * thrust); } }
