Operands for Sprites in a Sprite Track

kOperandSpriteBoundsLeft: No Params; The left side of the target sprite's bounding box in its track's local coordinate system is returned.
kOperandSpriteBoundsTop: No Params; The top of the target sprite's bounding box in its track's local coordinate system is returned.
kOperandSpriteBoundsRight: No Params; The right side of the target sprite's bounding box in its track's local coordinate system is returned.
kOperandSpriteBoundsBottom: No Params; The bottom of the target sprite's bounding box in its track's local coordinate system is returned.
kOperandSpriteImageIndex: No Params; The current image index of the target sprite is returned.
kOperandSpriteVisible: No Params; The current value of the target sprite's visible property is returned. The value is 1 if it is visible, and 0 if it is invisible.
kOperandSpriteLayer: No Params; The layer of the target sprite is returned.
kOperandSpriteID: No Params; The ID of the target sprite is returned. Note that if the ID has a value not expressable in a floating-point number, the results will not be the same.
kOperandSpriteIndex: No Params; The index of the target sprite is returned.
kOperandSpriteFirstCornerX: No Params; The x coordinate of the target sprite's first corner is returned.
kOperandSpriteFirstCornerY: No Params; The y coordinate of the target sprite's first corner is returned.
kOperandSpriteSecondCornerX: No Params; The x coordinate of the target sprite's second corner is returned.
kOperandSpriteSecondCornerY: No Params; The y coordinate of the target sprite's second corner is returned.
kOperandSpriteThirdCornerX: No Params; The x coordinate of the target sprite's third corner is returned.
kOperandSpriteThirdCornerY: No Params; The y coordinate of the target sprite's third corner is returned.
kOperandSpriteFourthCornerX: No Params; The x coordinate of the target sprite's fourth corner is returned.
kOperandSpriteFourthCornerY: No Params; The y coordinate of the target sprite's fourth corner is returned.
kOperandSpriteImageRegistrationPointX: No Params; The x coordinate of the target sprite's current image's registration point is returned.
kOperandSpriteImageRegistrationPointY: No Params; The y coordinate of the target sprite's current image's registration point is returned.
