C# 雪碧振动。怎么了?
我的敌人精灵在到达可变末端位置后一直振动。怎么了?为什么它会振动? 此外,变量next_position永远不会为真。但是为什么呢?我希望敌人的精灵在到达当前末端位置后移动到一个新的随机末端位置C# 雪碧振动。怎么了?,c#,xna,C#,Xna,我的敌人精灵在到达可变末端位置后一直振动。怎么了?为什么它会振动? 此外,变量next_position永远不会为真。但是为什么呢?我希望敌人的精灵在到达当前末端位置后移动到一个新的随机末端位置 public class Game1 : Microsoft.Xna.Framework.Game { GraphicsDeviceManager graphics; SpriteBatch spriteBatch; Texture2D enemy; Vector2 po

我对这句话有点困惑
if (Vector2.Dot(endposition - position, endposition - position) > 0 || Vector2.Dot(endposition - position, endposition - position) < 0)
其实就是这么简单,不需要其他检查。让我知道这是否适合你 我对这句话有点困惑
