A character cannot walk fast.

Adjust the walking speed of the character.

Change the frame rate of the document: in the document properties, increase the current frame rate, that is, the number of frames played in one second. This modification will make the whole animation faster. Conversely, if the frame adjustment is low, the animation will slow down. If audio is added, it may need to be readjusted to ensure synchronization between audio and images.

-Generally, motion animation is made by tween animation, which is usually the traditional tween animation. If you adjust the speed, it is enough to change the number of tweens between the two key frames. Moreover, the general walking animation and the scene action are together, and the action of the characters changes, and the scene action should be adjusted accordingly, so as to ensure the naturalness of the overall animation.
