game introduction
Unity development, by controlling the movement and attack of tanks, protecting the base and destroying enemy tanks.
development process
Background import and material processing
Select the backgrand in the material Graphics as the background.
If the material has not been divided and needs to be divided manually, click the material to be divided, select Multiple in Sprite Mode, click the Sprite Editor at the bottom right , select Apply to enter the segmentation page, click Slice at the upper left corner, select Slice, the system will automatically divide, and click Apply.
Formation of prefab and 2D animation
The formation of the prefab
Create a Prafads folder under the Project panel and drag the textures under the Hierarchy panel back to the Prafabs folder to form a prefab.
The formation of 2D animation
Hold down ctrl and drag multiple pictures into the Hierarchy panel, create an Animation folder, name it and save it to the Animation folder.
Control the player's movement and its direction
public void Move()
{
float i = Input.GetAxis("Horizontal");
transform.Translate(Vector3.right * i * MoveSpeed * Time.fixedDeltaTime, Space.World);//施加一个向右的力随时间的变化而变化乘以移速
if (i < 0)
{
sr.sprite = tanksprite[3];
bulletsprite = new Vector3(0, 0, 90);
}
else if (i > 0)
{
sr.sprite = tanksprite[1];
bulletsprite = new Vector3(0, 0, -90);
}
if (i != 0)
{
return;
}
float j = Input.GetAxis("Vertical");
transform.Translate(Vector3.up * j * MoveSpeed * Time.fixedDeltaTime, Space.World);
if (j < 0)
{
sr.sprite = tanksprite[2];
bulletsprite = new Vector3(0, 0, 180);
}
else if (j > 0)
{
sr.sprite = tanksprite[0];
bulletsprite = new Vector3(0, 0, 0);
}
}
player master code
public class Player : MonoBehaviour
{
//属性
public float MoveSpeed = 2;
private Vector3 bulletsprite;
private float time;
private float defenttime=5;
private bool isdefended=true;
//引用方法
public AudioClip attackAudio;//添加攻击音效
public AudioClip explorAudio;//添加爆炸音效
public SpriteRenderer sr;
public Sprite[] tanksprite;//上，右，下，左
public GameObject bulletPro;
public GameObject explortank;
public GameObject Shield0;
private void Awake()
{
sr = GetComponent<SpriteRenderer>();
}
Add a collider to solve the jitter
Add a rigid body and a collider to the player, and add a collider to other obstacles.
Click Constraints under the rigid body component to lock the Z axis to solve the rotation during movement.
Put the code in the FiexedUpdate life cycle function, because the fixed frame number can be Fix jitter
Tank's attack CD, mobile priority problem, level rendering
private void FixedUpdate()//固定物理帧
{
if(Playerstate.Instance.isDefent)
{
return;
}
Move();
//攻击CD
if (time >= 0.4f)
{
Attack();
}
else
{
time += Time.fixedDeltaTime;
}
}
The larger the Oorder in Layer, the higher the rendering level.
Tank attack method, invincible protection time

bullet script

Creation of player state management
Define the life value and score, which can be reflected in the UI interface in real time, death status, failure status, and call the corresponding method.

public bool isDefent;
public Text playerLifeText;

// Start is called before the first frame update
//
private static Playerstate instance;
public static Playerstate Instance {
get => instance; set => instance = value; }
private void Awake()
{

}
void Start()
{
}
// Update is called once per frame
void Update()
{
if(isDefent)
{

Invoke("ReturnMenu", 3);
}
if(dieplayer)
{
Reverce();
}

UI production

}
add sound effects
Audio Source components can be added by dragging and dropping.
