我试图让我的玩家走进我的 XNA 游戏，所以我设置了一个AnimatedTextureData类来接收一个继承正常纹理数据的动画精灵表。
动画纹理数据
namespace GDLibrary
{
public class AnimatedTextureData : TextureData
{
//width and height of a single frame inside the animation
private int frameWidth, frameHeight, numberOfFrames;
//this is a list containing all the source rectangle color data

public AnimatedTextureData(Main game, string path, int numberOfFrames, int frameWidth, int frameHeight)
: base()
{
this.texture = game.Content.Load<Texture2D>(@"" + path);
this.numberOfFrames = numberOfFrames;
this.frameWidth = frameWidth;
this.frameHeight = frameHeight;
this.sourceColorDataList = new List<Color[,]>(numberOfFrames);
setColorData(texture);
}
/// <summary>
/// Converts a Texture2D into a list of Color[,] array data
/// e.g. an image with 8 frames will have 8 Color[,] entries in the list.
/// Each Color[,] is a 2D array of color data for the frame.
/// This 2D color array is used for Non-AA CDCR - see Collision class
/// </summary>
/// <param name="texture"></param>
protected override void setColorData(Texture2D texture)
{
int width = texture.Width;
int height = texture.Height;
//read data into 1d array
Color[] colors1D = new Color[width * height];
texture.GetData(colors1D);
//create 2d array to store data
Color[,] colors2D = new Color[frameWidth, frameHeight];
//read each frame into a seperate colors2D array and add it to the list
//then when we want to now the color data for a particular frame we just query the list
for (int i = 0; i < numberOfFrames; i++)
{
for (int x = 0; x < frameWidth; x++)
{
for (int y = 0; y < frameHeight; y++)
{
colors2D[x, y] = colors1D[x + (y * frameWidth) + frameWidth * frameHeight * i];
}
}
sourceColorDataList.Add(colors2D);

纹理管理器控制数据，当您主要使用这些类时，您调用textureManager.Add("Example");
我在这里遇到的问题是它要我投射所以我试图投射到一个AnimatedTextureData但它不会让我。有任何想法吗？
AnimatedTextureData aniSpri = (AnimatedTextureData)textureManager.Get("AniSpri");
（AniSpri已经放入字典中TextureManager）
