    Gestures¶

    Ren'Py includes a gesture recognizer that is enabled when a touchscreen is used. This makes it possible for gestures to functions that would otherwise require a keyboard and mouse.

    The gesture recognizer first classifies swipes into 8 compass directions, "n", "ne", "e", "se", "s", "sw", "w", "nw". North is considered to be towards the top of the screen. It then concatenates the swipes into a string using the "_" as a delimiter. For example, if the player swipes down and to the right, the string "s_e" will be produced.

    Assuming config.dispatch_gesture is None, what happens next is that gesture is mapped to an event using config.gestures. If it is found, it is queued using renpy.queue_event(). Otherwise, the gesture is ignored.

    Gesture recognition is only enabled when "touch" is present in config.variants, which should be the case when running on a touchscreen device.

    config.gestures = { "n_s_w_e_w_e" : "progress_screen" }¶

    A map from gesture to the event activated by the gesture.

    config.dispatch_gesture = None¶

    The function that is used to dispatch gestures. This function is passed the raw gesture string. If it returns non-None, the interaction ends. If this variable is None, a default dispatch function is used.

    renpy.cancel_gesture()¶

    Cancels the current gesture, preventing the gesture from being recognized. This should be called by displayables that have gesture-like behavior.
