Method Detail

flingEvent

boolean flingEvent(android.graphics.Point start,
                 android.graphics.Point end,
                 GGVector velocity)

Event callback method called when a fling event occurs. The velocity is adapted to the current device resolution and corresponds to the physical speed in m/s.

start and end uses a pixel coordinate system with respect to the upper left vertex of the visible area in pixels.

The visible area corresponds to the full device window and is not restricted to the game grid window. (Therefore events are also generated, if a touch occurs within the status bar.) Use isInGrid() to check, if the coordinates are within the game grid window.

To convert the coordinates to game grid locations, use toLocation() or toLocationInGrid().

Parameters:

start - the starting point of the fling relative to the upper-left vertext of the visible window (same as GGTouch.press event reports)

end - the ending point of the fling relative to the upper-left vertext of the visible window (same as GGTouch.release event reports)

velocity - the velocity of the fling in the x-y coordinate system (in meter per seconds, zero at upper-left vertext of the visible window, vx positive to the right, vy positive downwards)

Returns:

true, if the event is consumed, so following listeners in the GGFlingListener sequence will not get the event
