Class Animation

Class Documentation

class Animation

Declaration: final

Independent cursor retaining shared immutable clip metadata, even after its CE::Assets::Sprites::Asset is released.

Copies copy playback state without retaining GPU handles. Advance on its simulation owner, then publish cell(); mutation is unsynchronized.

Public Functions

Animation &operator[](std::size_t frame)

Select a clip-frame ordinal via set_frame(), resetting within-frame time.

See also

void set_frame(std::size_t frame)

Select a clip ordinal and reset elapsed time inside it.

See also

Parameters:: frame – Ordinal; looping clips wrap, nonlooping clips clamp to their last frame. Mutation is unsynchronized and belongs to the simulation owner.

void advance(std::chrono::duration<double> elapsed)

Advance this independent cursor using simulation seconds.

See also

Parameters:: elapsed – Finite nonnegative duration; invalid values throw invalid_args before changing playback. Exact duration boundaries advance to the next frame; loops wrap efficiently and nonlooping clips hold the final frame. This does not update a shared asset, GPU handle or wall clock.
