Property ref allows to get a pointer to selected property in StateTree. The expected type of the reference should be set in "RefType" meta specifier.

Meta specifiers for the type:

• RefType = ""
• Specifies a comma separated list of type of property to reference
• Supported types are: bool, byte, int32, int64, float, double, Name, String, Text, UObject pointers, and structs
• Structs and Objects must use full path name
• If multiple types are specified, GetMutablePtrTuple can be used to access the correct type
• IsRefToArray
• If specified, the reference is to an TArray
• CanRefToArray
• If specified, the reference can bind to a Reftype or TArray
• Optional
• If specified, the reference can be left unbound, otherwise the compiler report error if the reference is not bound

Example:

// Reference to float

FStateTreePropertyRef RefToFloat;

// Reference to FTestStructBase

FStateTreePropertyRef RefToTest;

// Reference to TArray

FStateTreePropertyRef RefToArrayOfTests;

// Reference to Vector, TArray, AActor*, TArray

FStateTreePropertyRef RefToLocationLikeTypes;
