XML Format

Composition

The Composition element is used as the root of the file.

It contains FadeTransition elements, StitchTransition elements, Event elements, State elements, RSDFile elements, Stream elements, Clip elements and Region elements.

StateValue

A StateValue should be defined for each state inside the referenced State. Each StateValue can contain the various event actions listed previously.

</StateValue>

State

A State is referenced by an event that has multiple different music states that can be controlled by SetMusicState. It can contain Value elements.

	<State Name="Mission5">

Notes

The names of elements and attributes in this XML format are derived from Radical's official names as the RMS format stores all of the RadMusic class and field names within it.

Some other design decisions were derived from the plain text RMS format used in other Radical games such as The Incredible Hulk: Ultimate Destruction.

Items in this documentation that say "Unknown." are used in Hit & Run but their functionality is not understood.

Items in this documentation that say "Unused." are not used in Hit & Run and their functionality is not understood.
