Description
在 3D 空间中绘制一个平面圆盘的轮廓。
Wire Disc in the Scene View.
// Create a wire disc with a ScaleValueHandle attached to the disc
// that lets you drag the "areaOfEffect" var in the WireDiscExample.js
@CustomEditor (WireDiscExample)
class DrawWireDisc extends Editor {
function OnSceneGUI () {
Handles.color = Color.red;
Handles.DrawWireDisc(target.transform.position, Vector3.up, target.areaOfEffect);
target.areaOfEffect =
Handles.ScaleValueHandle(target.areaOfEffect,
target.transform.position + Vector3(target.areaOfEffect,0,0),
Quaternion.identity,
2,
Handles.CylinderCap,
2);
}
}
附加到此手柄的脚本：
//WireDiscExample.js
var areaOfEffect : float = 5;
