I’m Ayana, a Vtuber!
Today, I will explain about Path animation.
Prepare the object you want to move in advance.
In object mode, press Shift + A and click [Curve]> [Path].
This will add a path on the 3D viewport.
Press the Tab key to switch to edit mode and you can change the path to another shape. The shape can be easily changed by selecting and moving the fulcrum.
After deciding the shape of the path, right-click with the point that will be the starting point of the animation, and click Cursor to Selected from Snap.
Then, the 3D cursor will move to the start of the animation.
Press Tab to switch to object mode and select the object you want to move. In this state, right-click and click [Snap]>[Selection to Cursor].
Then, you can move the object to the starting point of the animation.
Rotate the object and adjust its orientation as you like.
After deciding the orientation, right-click with both the object and the path selected, then click [Parents]> [Follow Path]. This completes the path animation settings.
Click the play button on the timeline
In this way, you can move the object along the path you set.
Using of path animation
Now let’s add acceleration and deceleration movements to this animation.
With the path selected, click [Object Data Properties] to open the path animation.
Right-click on the evaluation time (green area) and click [Clear Keyframes]. This allows you to reset the default animation that moves at a constant speed once.
At this state, you can add acceleration / deceleration to the animation by inserting keyframes individually into any frame.
Now let’s actually insert a keyframe!
First, with the current frame set to “1” on the timeline, set the “evaluation time” value to 0.
Right-click on the evaluation time and click [Insert Keyframe]. Then, the evaluation time is displayed in yellow like this. In the same way, insert keyframes arbitrarily while moving the current frame.
This time, as an example, set “20” at the 40th frame, “90” at the 60th frame, and “100” at the 100th frame.
Then you can make the object move slowly like this.
Please try various path animations by all means!
This is the end of the explanation of path animation!
