Unity3d 序列幀動畫

序列幀動畫的實質是uv信息的變化，理解Tiling（圖片占得比例大小）和Offset（圖片的偏移量）。 默認左下角offset為0 0 Tiling為小圖/大圖

代碼如下：

public int rowNum ;

public int lineNum ;

 

public float iconwidth ;

public float iconheight ;

public int tileNum=6;

public float texWidth ;

public float texHeight ;

int achievementIndex=0;

float uWidth = 0;

float vHeight = 0;

// Use this for initialization

void Start () {

 

 

    uWidth=iconwidth/texWidth;

vHeight=iconheight/texHeight;

    InvokeRepeating("AnimationTexture",0,0.1f);

}

 

void AnimationTexture()

{   

if(achievementIndex>tileNum)

{

achievementIndex=0;

}

int rowIndex=achievementIndex/rowNum;

int lineIndex=achievementIndex%lineNum;

 

float uNums=lineIndex*uWidth;

float vNums=1-rowIndex*vHeight;

Vector2 size=new Vector2(uWidth,vHeight);

renderer.material.SetTextureOffset("_MainTex",new Vector2(uNums,vNums));

renderer.material.SetTextureScale("_MainTex",size);

achievementIndex++;

 

}
