Crate emotiva 

🎭 EmotivaHeart

EmotivaHeart is the central runtime of Emotiva.
It drives character animation, manages runtime state, and produces drawable outputs for rendering backends.

This struct is responsible for giving life to every character rig, updating animation systems each frame, and generating the forms that are ultimately rendered on screen.

Responsibilities

EmotivaHeart:

• Loads character rigs from .ron files (sprites, layers, variants)
• Holds runtime state for animation systems (tweens, motions, rotations, FX)
• Updates these systems every frame
• Outputs EmotivaForm values ready for rendering backends

Non-Responsibilities

EmotivaHeart does not:

• Perform rendering directly (handled by graphics backends)
• Expose all helper APIs itself (see the api modules for the public API)

Why “Heart”?

Because this struct acts as the runtime engine that keeps characters alive. It continuously updates motion, expression, and animation state, allowing rendering backends to display the current character pose.

Designed to integrate smoothly with visual novel engines and other Rust game frameworks.
