DrawLine是给定起点和终点。DrawRay是给定起点和方向。不同情况下一个会比另一个更方便。Debug.DrawLine：Draws a line between specified start and end points.这才是你需要的，不是知乎，Unity - Scripting API:
Gizmos.DrawLine 绘制的线条颜色和材质是固定的,无法调整其粗细、透明度或使用自定义材质。 1、绘制网格 using UnityEngine; public class DrawGrid : MonoBehaviour { public float gridSize = 1.0f; // 网格单元的大小 public int gridSizeX = 10; // 网格的列数 public int gridSizeY = 10; // 网格的行...
如果只是简单的为了 Debug 的目的画线的话,建议使用Debug.DrawLine // draw a 5-unit white line from the origin for 2.5 secondsDebug.DrawLine(Vector3.zero,newVector3(5,0,0),Color.white,2.5f); 页面也写了 for debugging playmode only. LineRenderer LineRenderer正如它的界面所写: The line render...
其中,interval用来控制点与点之间的间距,然后利用GL完成点连线: void DrawLine() { if (!beginDraw) return; GL.PushMatrix(); GL.LoadOrtho(); lineMaterial.SetPass(0); GL.Begin(GL.LINES); for (int i = 0; i < posList.Count - 1; i++) { Vector3 pos = posList[i]; GL.Vertex3(pos....
