Rotating
(mobject, **kwargs)¶
RotatingExample¶
class RotatingExample(Scene):
def construct(self):
square=Square().scale(2)
self.add(square)
self.play(
Rotating(
square,
radians=PI/4,
run_time=2
)
)
self.wait(0.3)
self.play(
Rotating(
square,
radians=PI,
run_time=2,
axis=RIGHT
)
)
self.wait(0.3)

Rotate
(mobject, angle=3.141592653589793, axis=array([0.0, 0.0, 1.0]), **kwargs)¶
RotateExample¶
class RotateExample(Scene):
def construct(self):

self.add(square)
self.play(
Rotate(
square,
PI/4,
run_time=2

Rotate和Rotating的区别:
Rotate
目前是 Transform
的子类,即带有 path_arc
的 Transform
,所有会有扭曲
Rotating
直接继承自 Animation
,根据角度插值,比较顺滑,推荐使用
另外,请不要尝试直接使用 ApplyMethod
或 self.play(mob.rotate, ...)
来旋转,
因为这只是在当前和结果之间进行 Transform
,并无旋转效果
