锥光方向 Degree 参数什么都不做我给的值是什么？

Question

coneLight = new ConeLight(rayHandler,100,Color.WHITE,200/PPM,0,0,30,30); At directionDegree = 30

    coneLight = new ConeLight(rayHandler,100,Color.WHITE,200/PPM,0,0,60,30);

At directionDegree = 60

    coneLight = new ConeLight(rayHandler,100,Color.WHITE,200/PPM,0,0,130,30);

At directionDegree = 130

为什么在所有情况下（方向度的不同值）都会出现相同的结果？

Answer 1

将灯光附加到物体上会导致灯光忽略为灯光设置的任何角度偏移。

为了在连接到主体时添加角度偏移，请使用

light.attach(body, x, y, degrees);

Cone light direction Degree parameter doing nothing what ever value i give?
