我有这个代码:
public class Area
{
Texture2D point;
Rectangle rect;
SpriteBatch _sB;
GameTimer _gt;
int xo, yo, xt, yt;
//List<Card> _cards;
public Area(Texture2D point, SpriteBatch sB)
{
this.point = point;
this._sB = sB;
xt = 660;
yt = 180;
xo = 260;
yo = 90;
}
public void Draw(SpriteBatch spriteBatch)
{
rect = new Rectangle(660, 180, 80, 120);
spriteBatch.Draw(point, rect, Color.White);
_gt = new GameTimer();
_gt.UpdateInterval = TimeSpan.FromSeconds(0.1);
_gt.Draw += OnDraw;
}
private void OnDraw(object sender, GameTimerEventArgs e)
{
this.pass(xo, yo);
if (xo != xt) xo += (xt > xo) ? 10 : -10;
if (yo != yt) yo += (yt > yo) ? 10 : -10;
}
public void pass(int x, int y)
{
rect = new Rectangle(x, y, 80, 120);
_sB.Draw(point, rect, Color.Black);
}
}
所以,我不明白出了什么问题。这是我使用 XNA 的第一个项目,因此可能会出现愚蠢的错误 :)
PS对不起。有一个坐标为(xt,yt)的矩形,我需要动画将矩形移动到(xo,yo)
PPS 我添加了带有更正的完整课程,因为我不明白我的错误。
