试图做出 Seek and Flee 行为。无法将类型 'void' 隐式转换为 'Microsoft.Xna.Framework.Vector2'

Question

我正在尝试为 AI 项目制作 Seek and Flee 行为。我尝试输入算法，但出现此错误。我不明白为什么它不起作用，我可以使用一些指导。

这是无法正常工作的代码段：

public Vector2 Seek(Vector2 source, Vector2 target, float maxAccel)
{
     Vector2 acceleration = (target - source).Normalize() * maxAccel;
     return acceleration;

}

Answer 1

Normalize()函数的documentation for the Normalize() function says it returns a void, but you're trying to assign it to a variable of type Vector2. You'll probably want to use this variant如下：

Vector2 acceleration = Vector2.Normalize(target - source) * maxAccel;

我假设 target 和 source 都是 Vector2 类型并且 maxAccel 是标量值。
