Parameter Streams

TL;DR: A CVRParameterStream component reads from one of the named sources below and writes the result into an animator parameter, a CVRVariableBuffer, a custom spawnable float, or an avatar animator parameter. The full CVRParameterStreamEntry.Type enum — with stable numeric IDs — is reproduced here. Numeric IDs are stable across CCK versions because they’re persisted in serialized assets; gaps preserve backwards compatibility as the enum was extended.

How a stream entry works

Each entry has:

• type — which data source to read (the table below)
• targetType — Animator, VariableBuffer, AvatarAnimator, or CustomFloat
• applicationType — Override, AddToCurrent, MultiplyWithStatic, Clamp, Remap, CompareEquals, etc.
• staticValue (and up to staticValue4) — operands for additive/multiplicative/comparison/clamp/remap modes
• parameterName, target — the destination

CVRParameterStreamEntry.CheckUpdate(stream, slowUpdate) runs every Unity update (or slow-update for VariableBuffer targets), reads the source value into a local value (or intValue for seed sources), applies the chosen application, and writes the result.

The AvatarAnimator target routes through PlayerSetup.ChangeAnimatorParam, so all the read-only/AAS guards from Animator Parameters still apply.
