Set/Reset Constant Velocity

设置/重置恒定速度

Let’s say you are working with the animation path pictured above (the animation’s spatial F-Curve can be modified using the Bezier handles with the Auto Tangent key option deactivated). As you can see based on the point intervals along the path, the spacing between points at the beginning of the path is much different from that at the end of the path, affecting the animation speed accordingly. If you want the object to move along the path at a constant velocity, select the corresponding tracks and select Set Constant Velocity from the Timeline’s Functions menu. Selecting Reset Constant Velocity will return the object’s velocity to its previous state (based on the point intervals).

让我们假设您正在使用上图中的动画路径(动画的空间 f 曲线可以使用 Bezier 手柄修改，自动切线按键选项停用)。正如你所看到的，基于沿着路径的点间隔，路径开始的点之间的间距与路径结束的点之间的间距有很大的不同，这相应地影响了动画的速度。如果你想让物体以恒定的速度沿着路径移动，选择相应的轨迹并从时间线的函数菜单中选择设置恒定的速度。选择 Reset Constant Velocity 将返回物体的速度到其先前的状态(基于点间隔)。

What actually happens when this command is selected: The Track parameters’Constant Velocity option will be enabled or disabled.

当选择这个命令时实际发生的情况: Track 参数的恒速选项将被启用或禁用。
