Remarks
Prepares rapid iteration parameter stores for simulation by removing old parameters no longer used by functions, by initializing new parameters added to functions, and by copying parameters across parameter stores for interscript dependencies.
Parameters
| Name | Description |
|---|---|
| Scripts | The scripts who's rapid iteration parameter stores will be processed. |
| ScriptDependencyMap | A map of script dependencies where the key is the source script and the value is the script which depends on the source. All scripts in this map must be contained in the Scripts array, both keys and values. |
| ScriptToEmitterNameMap | An array of scripts to the name of the emitter than owns them. If this is a system script the name can be empty. All scripts in the scripts array must have an entry in this map. |
