A one-shot state (`once`) loops, hands over to a state that does not exist or to itself, lets an undefined state interrupt it, has a negative `blendOut`, or raises an empty event name.

## Messages

The message opens with the code; `<…>` stands for a value.

- `one-shot state "<…>" hands over to itself, which replays it for ever; that is "loop": true`
- `one-shot state "<…>" hands over to undefined state "<…>"`
- `one-shot state "<…>" has "loop": true, so its clip never reaches the end it hands over at`
- `one-shot state "<…>" has a negative blendOut (<…>)`
- `one-shot state "<…>" may be interrupted by undefined state "<…>"`
- `one-shot state "<…>" plays a list of clips; a one-shot plays one clip or one blend tree`
- `one-shot state "<…>" raises an event with an empty name`
