> Talos 0.6 · Since 0.6

An animator state's or blend point's `speed`, or a `speedParam.scale`, is negative, NaN or infinite, or a `speedParam` names a parameter the animator does not declare.

## Messages

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

- `state "<…>" asks a <…> blend tree for strideMatch; stride matching reads one parameter as a ground speed, so it takes a linear tree`
- `state "<…>" blend point <…> (<…>) has refSpeed <…>; a ground speed must be a finite number of m/s, 0 or more`
- `state "<…>" blend point <…> (<…>) has speed <…>; a playback rate must be a finite number, 0 or more`
- `state "<…>" has speed <…>; a playback rate must be a finite number, 0 or more`
- `state "<…>" has speedParam.scale <…>; it must be a finite number, 0 or more`
- `state "<…>" takes its speed from parameter "<…>", which the animator does not declare in "parameters"`
