Gestures on android - Hold gesture? How do I add events?

#1 Post by GlassHeart »

Hello! I've been trying to replace on screen buttons with gestures for my android app, but I am a bit stuck.

init:
$ config.gestures["s"] = "game_menu" #swipe down to open the menu
$ config.gestures["e"] = "skip" #swipe right to skip
$ config.gestures["w"] = "rollback" #swipe left to see previous line
#$ config.gestures["n"] = ? #swipe up to quick save


This is what I have so far. What I want to know is how to add the quick save feature as a swipe up. For the others I've been using the events found in the default keymap here. But there is no quick save there so I am a bit lost. How can I add other events such as qs or auto forward?

Another related question is: are there any other simple gestures that I can use for auto or other functionalities? Such as press and hold, two-finger tap or something similar? I know I can use L-shapes, but I just wanted to know my options.

Thank you very much for reading. Help is greatly apreciated.

It's a little indirect. The right way to do this is with a screen that maps keys to actions:

Code: Select all

screen my_keymap:
     key "auto" action Preference("auto-forward", "toggle")
     key "quick_save" action QuickSave()
And then use config.gestures to map those.

Code: Select all

config.gestures['n'] = "quick_save"
config.gestures['n_e_s'] = "auto"
That being said - I'd really reconsider using gestures instead of buttons. They seem very confusing in practice. (The feature only exists so I can access the super-secret progress screen on Android by using a gesture-based version of the Konami code.)

Thanks for replying, Tom.
I've tried to do as you said but the gesture was not working (all the others are working fine). I attempted to replace gestures with a random key to see if that would make a difference.
Something like this: config.keymap['auto'].append('t')

I got an error which to me sounds like "auto" is not defined properly.

While running game code:
File "game/options.rpy", line 1437, in <module>
config.keymap['auto'].append('t')
KeyError: 'auto'


For anyone wondering, I did manage to fix the problem in another way thanks to Alex by reading this post.

I defined my screen as
screen my_keymap:
key "t" action Preference("auto-forward", "toggle")


Then configured the gesture for swipe down as
config.gestures["s"] = "t"

Then showed the screen at the beginning of the game
show screen my_keymap

This also causes the key "t" to toggle auto, but since I intend to use this on mobile, it shouldn't affect it. It may not be the best solution, but it works well as far as I can tell.

can you share the code you used to get the gestures to work @GlassHeart, I only keep getting errors when I try to use them. It would really help me out and also we should put the code in screens.rpy, right?
