#pragma once
#include "DrawDebugHelpers.h"

//绘制圆
#define DRAW_SHERE(Location)\
if(GetWorld())DrawDebugSphere(GetWorld(),Location,100.f,12,FColor::Red,true);
//绘制直线
#define DRAW_LINE(startLocation,endLocation)\
if(GetWorld())DrawDebugLine(GetWorld(),startLocation,endLocation,FColor::Red,true,-1.f,0,1.f);
//绘制点
#define DRAW_POINT(Location)\
if(GetWorld())DrawDebugPoint(GetWorld(),Location,25.f,FColor::Red,true,-1.f,0);
//绘制一个带点的直线，点在直线末尾
#define DRAW_Vector(startLocation,endLocation)\
if(GetWorld())\
{\
	DrawDebugLine(GetWorld(), startLocation, endLocation, FColor::Red, true, -1.f, 0, 1.f);\
	DrawDebugPoint(GetWorld(),endLocation,15.f,FColor::Red,true,-1.f,0);\
}

\的作用是连接下一行字符串

创建一个工具头文件储存这个宏

注意地址，要改到source文件夹里，默认放在Intermediate里，这个文件夹会在编译的时候被删除重建，不要放在这里
