Animating an actor
After importing and rigging an actor, you can begin animating by simply dragging the rigged actor into the Scene view. By repositioning the different bones of the actor on the Animation timeline with Unity's animation workflow and tools. The mesh of the actor deforms with the positioning of the rigged bones, creating the animation.
Aside from this method, there are other ways that you can animate with the 2D Animation packge. The following are a few examples based on the Sample projects available for you to import to use with the package.
Sprite Swap
The 2D Animation package allows you to use the Sprite Swap feature to swap to different Sprites at runtime, from swapping only a single part of an actor to swapping the entire Sprite Library Asset it refers to.
Frame-by-frame animation
By using Sprite Swap, you can create frame-by-frame style animations by swapping to different Sprites on each frame at runtime. Refer to the Frame-by-frame Animation documentation for more detailed information on how you can achieve this animation style.
Other Sample projects
Sample projects are distributed with the 2D Animation package and available for import. These projects include examples of the different ways you can animate with the package features, such as the Flipbook Animation Swap and Animated Swap and so on. Refer to the respective Sample documentation pages for more information.
