Unity mouse cursor usage learning

UnityThe mouse cursor program below is related to one class2、3个方法.

首先,The settings for the cursor to import pictures need to be set to typeCursor.

There is only one way to set the mouse cursor,SetCursor.第一个参数是图片,The second parameter is the offset of the click point,The third parameter is the type.

    public Texture2D texture;
    void Start()
    {
    
        Cursor.SetCursor(texture, new Vector2(40, 4), CursorMode.Auto);
    }

当使用CursorMode.Auto的时候,Will use hardware for cursor processing.性能好,兼容好.但是,在windows系统下,will force the cursor to shrink to 32*32.

当使用CursorMode.ForceSoftware的时候,Software will be used to handle the cursor.在windowsThis is the only way to make the mouse cursor bigger under the system,But occasionally there are small onesbug.在使用中发现unity2022.1+HDRP环境下,Image will darken.

If you want to achieve icon animation,Only one picture can be replaced in turn.CodeMonkeyThe big guy has the code to provide cursor animation,我就直接抄过来了.

public class CursorAnimation : ScriptableObject
{
    
    public CursorType cursorType;
    public Texture2D[] textureArray;
    public float frameRate;
    public Vector2 offset;
}

public class CursorMananger : MonoBehaviour
{
    
    public CursorAnimation[] cursorAnimations;
    private CursorAnimation currentAnimation;

    private float frameRate;
    private int frameCount;
    private int currentFrame;
    private float frameTimer;

    private void Start()
    {
    
        SetActiveCursorAnimation(cursorAnimations[0]);
    }

    private void Update()
    {
    
        frameTimer -= Time.deltaTime;
        if (frameTimer <= 0f)
        {
    
            frameTimer += frameRate;
            currentFrame = (currentFrame + 1) % frameCount;
            Cursor.SetCursor(currentAnimation.textureArray[currentFrame], currentAnimation.offset, CursorMode.Auto);
        }

        if (Input.GetKeyDown(KeyCode.A)) SetActiveCursorAnimation(cursorAnimations[(int)CursorType.Arrow]);
        if (Input.GetKeyDown(KeyCode.S)) SetActiveCursorAnimation(cursorAnimations[(int)CursorType.Star]);
    }

    private void SetActiveCursorAnimation(CursorAnimation value)
    {
    
        currentAnimation = value;
        currentFrame = 0;
        frameTimer = value.frameRate;
        frameCount = value.textureArray.Length;
    }
}
