Resets an exposed parameter to its initial value.

Exposed parameter. Returns false if the parameter was not found or could not be set.

Connected groups in the mixer form a path from the mixer's master group to the leaves. This path has the format "Master GroupChild of Master GroupGrandchild of Master Group", so to find the grandchild group in this example, a valid search string would be for instance "randchi" which would return exactly one group while "hild" or "oup/" would return 2 different groups.

Sub-string of the paths to be matched. Groups in the mixer whose paths match the specified search path.

The name must be an exact match.

Name of snapshot object to be returned. The snapshot identified by the name.

Returns the value of the exposed parameter specified. If the parameter doesn't exist the function returns false. Prior to calling SetFloat and after ClearFloat has been called on this parameter the value returned will be that of the current snapshot or snapshot transition.

Name of exposed parameter. Return value of exposed parameter. Returns false if the exposed parameter specified doesn't exist.

Sets the value of the exposed parameter specified. When a parameter is exposed, it is not controlled by mixer snapshots and can therefore only be changed via this function.

Name of exposed parameter. New value of exposed parameter. Returns false if the exposed parameter was not found or snapshots are currently being edited.

Transitions to a weighted mixture of the snapshots specified. This can be used for games that specify the game state as a continuum between states or for interpolating snapshots from a triangulated map location.
