ClosestartPosition | The start point of the bezier line. |
endPosition | The end point of the bezier line. |
startTangent | The start tangent of the bezier line. |
endTangent | The end tangent of the bezier line. |
color | The color to use for the bezier line. |
texture | The texture to use for drawing the bezier line. |
width | The width of the bezier line. |
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.
Note: Use HandleUtility.GetHandleSize where you might want to have constant screen-sized handles.
Bezier Line in the Scene View.
using UnityEditor; using UnityEngine;
[CustomEditor(typeof(BezierExample))] public class DrawBezierExample : Editor { void OnSceneGUI() { BezierExample be = target as BezierExample;
be.startPoint = Handles.PositionHandle(be.startPoint, Quaternion.identity); be.endPoint = Handles.PositionHandle(be.endPoint, Quaternion.identity); be.startTangent = Handles.PositionHandle(be.startTangent, Quaternion.identity); be.endTangent = Handles.PositionHandle(be.endTangent, Quaternion.identity);
// Visualize the tangent lines Handles.DrawDottedLine(be.startPoint, be.startTangent, 5); Handles.DrawDottedLine(be.endPoint, be.endTangent, 5);
Handles.DrawBezier(be.startPoint, be.endPoint, be.startTangent, be.endTangent, Color.red, null, 5f); } }
