错误在Unity：Lightning.SetColors（彩色，彩色）”必须有一个主体，因为它未标记抽象，EXTERN，或部分

Question

的误差是完全：

错误（1）

资产/ _dinostudios123 /匹配树引擎/脚本/效果/ Lightning.cs（7,14）：错误CS0501：`Lightning.SetColors（Color，Color）'必须有一个主体，因为它没有标记为抽象，外部或部分

此错误是由于必须添加public void SetColors（Color start，Color end）而改变[line.SetColors（color，color）;]所致。

错误（2）

资产/ _dinostudios123 /匹配树引擎/脚本/效果/ Lightning.cs（30,14）：警告CS0618：UnityEngine.LineRenderer.SetVertexCount(int)' is obsolete:使用numPositions不是“。

任何人都可以确定为什么在添加代码行以纠正颜色开始和颜色结束并纠正每行的int数时会出现错误代码？

Answer 1

编译器警告你，你定义的参数，但没有尸体的方法。

调整您的格式可以更容易地看到它在抱怨：

public void SetColors(Color start, Color end); 

public void SetVertexCount(int count); 

您需要定义机构的那些方法。

public void SetColors(Color start, Color end) 
{ 
    // set the starting and ending colors 
} 

public void SetVertexCount(int count) 
{ 
    // set the vertex count 
}
