editor.rc

Remote Control passthrough to any BlueprintCallable function or BlueprintVisible property on any UObject

`editor.rc.call`

Invoke any BlueprintCallable function on any UObject via RemoteControl's ResolveCall/InvokeCall pipeline.

Parameters:

Name	Type	Required	Description
`objectPath`	string	Yes	Full path to the target UObject
`functionName`	string	Yes	Name of the BlueprintCallable function to invoke
`parameters`	object	No	Key-value pairs matching the function's input parameters
`generateTransaction`	boolean	No	If true, wraps the call in an undo transaction (default: false)

Returns:

Name	Type	Description
`success`	boolean	Always true on success
`objectPath`	string	The resolved object path
`functionName`	string	The function that was called
`returnValue`	string	The return value exported as text (if function has a return type)
`outParams`	object	Any output parameters as key-value string pairs (if function has out params)

`editor.rc.property`

Read or write any BlueprintVisible property on any UObject. Omit value to read; include value to write.

Parameters:

Name	Type	Required	Description
`objectPath`	string	Yes	Full path to the target UObject

`generateTransaction`	boolean	No	If true, wraps the write in an undo transaction (default: false)

Returns (read):

Name	Type	Description
`success`	boolean	Always true on success
`objectPath`	string	The resolved object path

`action`	string	"read"

Returns (write):

Name	Type	Description
`success`	boolean	Always true on success
`objectPath`	string	The resolved object path
`propertyName`	string	The property that was written
`action`	string	"write"
