tank battle

1. Image material import

　　Change the Texture Type to Sprite (2D and UI).

　　　　

　　The atlas (one image contains multiple pictures) should set the Sprite Mode to Multiple.

　　　　

 

 2. Create animation

　　The easiest way is to drag all the pictures directly to the Hierarchy window, you can create animations directly.

 

3. Change the display of Sprite

　　Modify the sprite of the SpriteRenderer.

1  if (h> 0 )
 2  {
 3      sr.sprite = tankSprites [ 1 ];             //右
4  }
 5  else  if (h < 0 )                              //左
6  {
 7      sr.sprite = tankSprites [ 3 ];
8 }

 

 

4. 2D Colliders

　　

 

 5. FixedUpdate

　　Used for physical rigid body movement.

 　　

6. Euler angle to quaternion

Quaternion.Euler();

 

 

7. Trigger detection

　　Add BoxCollider2D and check isTrigger.

　　　　

　　Common functions are:

 1 void OnTriggerEnter2D(Collider2D other)
 2 {
 3 }
 4 void OnTriggerExit2D(Collider2D other)
 5 {
 6 }
 7 
 8 void OnTriggerStay2D(Collider2D other)
 9 {
10 }

 

 

 8. Delayed execution of functions

Invoke("InitPlayer", 1f);

 　　

9. Singleton Pattern

 1 private static PlayerManage instance;
 2 
 3 public static PlayerManage Instance
 4 {
 5     get { return PlayerManage.instance; }
 6     set { PlayerManage.instance = value; }
 7 }
 8 
 9 void Awake()
10 {
11     Instance = this;
12 }

 

 

10. Load the scene

1 using UnityEngine.SceneManagement;
2 SceneManager.LoadScene("OtherSceneName",LoadSceneMode.Additive);
