public static void DrawBezier (Vector3 startPosition, Vector3 endPosition, Vector3 startTangent, Vector3 endTangent, Color color, Texture2D texture, float width);

参数

startPosition 贝塞尔曲线的起点。
endPosition 贝塞尔曲线的终点。
startTangent 贝塞尔曲线的起始切线。
endTangent 贝塞尔曲线的终点切线。
color 要用于贝塞尔曲线的颜色。
texture 要用于绘制贝塞尔曲线的纹理。
width 贝塞尔曲线的宽度。

描述

Draw textured bezier line through start and end points with the given tangents. To get an anti-aliased effect use a texture that is 1x2 pixels with one transparent white pixel and one opaque white pixel. The bezier curve will be swept using this texture.

注意:如果您希望拥有恒定屏幕大小的手柄,请使用 HandleUtility.GetHandleSize。

\ 场景视图中的贝塞尔曲线。

    // Draws a red bezier curve from (0,0,0) to the transform's position

@CustomEditor (BezierScript) class DrawBezierHandle extends Editor {

function OnSceneGUI() { var width : float = HandleUtility.GetHandleSize(Vector3.zero) * 0.1; Handles.DrawBezier(target.transform.position, Vector3.zero, Vector3.up, -Vector3.up, Color.red, null, width); } }

附加到此手柄的脚本:

    //BezierScript.js

Debug.Log("I have a bezier curve handle attached!");
