Movement Data Structure

The movement data structure provides data from elements of kind kISpElementKind_Movement. This element kind produces data that is given both as x-y axis data and directional pad data, allowing the game to use whichever is suitable. The movement data structure is defined by the ISpMovementData data type.

typedef struct ISpMovementData {
   UInt32         xAxis;
   UInt32         yAxis;
   UInt32         direction; 
};

Field Description
