scummVM change keyboard maps on gamepad

coldnpale

noob question: Before doing all this, should I install normally scummvm? Or is this not needed since it is done after building and installing?

@ectoone
This is interesting since there are some buttons available. How would I go adding the "ALT" Keyboard button? By replacing "F1" in your example with "ALT" or "RALT" or something?

@coldnpale No, you carry out the commands in a terminal session instead of installing from the setup script.

Also, it is these lines in the sdl-events.cpp file that you will need to edit.

@dudleydes
got it! Thanks!

So.. I used jstest to find the correct controller buttons for my logitech F710. Apparently for my controller it has to be

#define JOY_BUT_LMOUSE 0
#define JOY_BUT_RMOUSE 2
#define JOY_BUT_ESCAPE 3
#define JOY_BUT_PERIOD 1
#define JOY_BUT_SPACE 8
#define JOY_BUT_F5 9

Now I just need to wait some time to build it

@coldnpale If you take a look at the lines 350+ in the sdl-events.cppfile, you can see all SDLK_* and KEYCODE_* values. In your case you need to use LALT or RALT.

So, thanks to dudledes and EctoOne I managed to map the buttons! I appreciate a lot your help, thanks a lot for taking the time to guide me so thoroughly!

One last question, if I need to change/add buttons will I have to repeat the process again? I am asking in case of an update. I guess if I update the scummvm the controls will be overwritten.

@coldnpale Glad to hear it worked.

You should use the above method to change or add buttons or if you wish to update to a new version of ScummVM. Installing from the setup script will have the default gamepad mappings.

@dudleydes
Better than nothing. At least we have a means to make the changes. I guess I won't be updating too often though ... :P

Some games block F5 key. So i map the combination ctrl+f5 to the left button of my ps3 controller.

#define JOY_BUT_LMOUSE 14
#define JOY_BUT_RMOUSE 13
#define JOY_BUT_ESCAPE 15
#define JOY_BUT_PERIOD 12
#define JOY_BUT_SPACE 0
#define JOY_BUT_F5 3
#define JOY_BUT_MENU 10

                case JOY_BUT_MENU:
                        event.kbd.flags = Common::KBD_CTRL;
                        event.kbd.keycode = Common::KEYCODE_F5;
                        event.kbd.ascii = mapKey(SDLK_F5, (SDLMod)ev.key.keysym.mod, 0);
                        break;

Guys, give a try to the lr-scummvm libretro-based core for ScummVM I put for testing here: https://retropie.org.uk/forum/topic/19693/lr-scummvm-request-for-comments-and-testing/

You can do mappings via RetroArch and customise for each game too easily with RA. Also you can use any RA-supported shader. So far it has been working nice for me, would appreciate feedback from other ScummVM players.
