Handles.MakeBezierPoints

説明

Retuns an array of points to representing the bezier curve.

The division argument provides the number of lines used to make the bezier curve.

Additional resources: Handles.DrawBezier.

using UnityEngine;
using UnityEditor;

// Generates 20 points that define the bezier curve

[CustomEditor(typeof(DrawBezier))]
public class DrawBezierExample : Editor
{
    private Vector3[] points;

    private void OnSceneGUI()
    {
        points = Handles.MakeBezierPoints(
            new Vector3(1.0f,  0.0f,   0.0f),
            new Vector3(-1.0f,  0.0f,   0.0f),
            new Vector3(-1.0f,  0.75f,  0.75f),
            new Vector3(1.0f, -0.75f, -0.75f),
            20);

        Handles.DrawAAPolyLine(points);
    }
}

This is the second script:

using UnityEngine;

// The class called by the DrawBezierExample

public class DrawBezier : MonoBehaviour
{
    // no script needed, just the class
}
