Demo mode can't be stopped with using only gamepads / joysticks

[joyrider3774]

Hi,

It would seem demo mode where the cpu's fight each other, can't be stopped if the only input device is a game pad / joystick.

I don't know if this was also the case in the original game, but i though i'd mention it. I was testing using latest git on a RG35XX handheld which only had gamecontroller support (i edited the conf files to be able to control game) but it seems at least the demo mode i can't seem to exit using a gamecontroller only

Unfortunately I don't have a handheld or gamepad to test this with. Can you copypaste your mappings from the config file, and the start of the logfile (from start until "--- BEGIN GAME LOG ---") ?

i could not control the game initially (no keyboard) but i knew the name of gamepad so edited the config to only change the joy_name1 , ctrl_type1and joy_offset1 value, i did not change anything else. I can play the game fine and everything seems to work except i can't quit demo mode using the gamepad only almost seemingly as if a check on it is missing but not sure how it is all mapped internally

ctrl_type1=1
joy_name1="Deeplay-keys"
joy_offset1=0
key1_jump_up="Up"
key1_jump_right="PageUp"
key1_walk_right="Right"
key1_duck_forward="PageDown"
key1_duck="Down"
key1_duck_back="End"
key1_walk_back="Left"
key1_jump_left="Home"
key1_kick="Right Shift"
key1_punch="Return"
key1_escape="Escape"             

i also provided a gamecontrollerdb.txt file in share/games/openomf containing these values

I looked through the code, and found the issue, the ESCAPE key in demo is handled here but only explicit keyboard input is handled here no gamepad at all and thats why you can not exit demo if using gamepads / joysticks only. see

openomf/src/game/scenes/arena.c

Line 1036 in 05ade32

int arena_event(scene *scene, SDL_Event *e) {

it needs a part added for gamepad controls as well

[katajakasa]

Right. This issue is due to the normal input code only accepting escape input from player one. Since player one is a computer in demo mode, this hack was added to get out (when using keyboard). There was no similar out added for game controllers.

To fix, this requires changes to arena_handle_events(). Another ticket to backlog.
