Enumeration Type Documentation

◆ eCreateDriver_MappingTypes

enum eCreateDriver_MappingTypes

Heuristic to use for connecting target properties to driven ones

Enumerator
CREATEDRIVER_MAPPING_1_N	1 to Many - Use the specified index, and drive all elements with it
CREATEDRIVER_MAPPING_1_1	1 to 1 - Only for the specified index on each side
CREATEDRIVER_MAPPING_N_N	Many to Many - Match up the indices one by one (only for drivers on vectors/arrays)
CREATEDRIVER_MAPPING_NONE	None (Single Prop): Do not create driver with any targets; these will get added later instead
CREATEDRIVER_MAPPING_NONE_ALL	None (All Properties): Do not create driver with any targets; these will get added later instead
