1. Understand the running posture and action rules:

Step-by-step action: Role running is a continuous action sequence, which needs to be manifested from starting to accelerating, then maintaining the speed, and finally slowing down and stopping.

Center of gravity and rhythm: the center of gravity of running changes constantly during the exercise, and the movements of the characters also change accordingly. Pay attention to the rhythm and pace of the center of gravity movement.

Range of motion: When running, the coordination between the upper body and the lower body is very important, so pay attention to the swing range of the arms and legs and the inclination of the trunk.

2. Use Animate to make running animation:

Role design: draw or import the roles needed to run in Animate. Ensure that the character design meets the proportion and movement ability required for running.

Decomposition action: Decompose the running action into key frames, and draw or set the posture of the character frame by frame from the beginning to the acceleration and then to the deceleration.

Use keyframe animation: Use the keyframe animation function in Animate to gradually set the position, posture and action details of the characters in each frame. Create a smooth animation by adding keyframes.

Key parts: Pay special attention to the legs, hips and arms of the characters, which are the most obvious and important parts of running movements.

Adjust the speed and curve: use the timeline function of Animate to adjust the speed and curve of the animation to make the running animation look more natural and smooth.

Add details: add some details to the character animation, such as the shaking of the head and the swinging of clothes. To make the animation more vivid and realistic.

Circular animation: For continuous movement (such as running), you can create a circular animation sequence to make the running movement repeat continuously, presenting a long-term continuous running.

3. Practice and improvement:

Observation Reference: Observing the running movements of characters in reality and the running scenes in other excellent animations, and comparative analysis will help to improve your animation.

Feedback and correction: After the animation is made, it will be continuously corrected and improved by watching and receiving feedback, so as to make the animation more in line with the reality of running.

Through these steps, you can use Adobe Animate to make more realistic and smooth animation. Remember, it takes time and care to draw running animation, and continuous practice and attempt can improve the animation quality.
