Food Fight - joystick troubles, solved
-
to be honest the game should re calibrate when you use it a while the game is coded this way. The grid you work out can change you need to know what the self calibrating code is doing in the game.
The ps2/3/4/xbox360 pads are useless for this game the analog resolution its too low on them its not too bad on a xbox one though. the digital code leaves you facing your last direction if you code it properly i have no issues with it. I will test this on the pi and let you know if i have any issues with the digital. The thing with the original is the joystick might not have self centered either.
-
@grant2258 so you're saying if you use a Xbox one controller analog stick it doesn't snap right everytime you stop? And because PS2 analog has less range it snaps right?
I have no issue with digital with the fix implemented here. I'll probably just optimize the hell out of it and test and bugs.
-
@mahoneyt944 yes if its centered it will snap right but it has a higher resolution you can circle the eyes easier ect
-
@grant2258 oh I see..... Well I don't care about moving the eyes when I'm stopped, as long as I stop facing where I last pressed. So this fix does just that for analog and digital. But the side effect is it reduces analog to 8 way movements....Since we are returning set movements and stops instead of actual positions when centering.
-
im lost now the digital code on runs when you set the cheat options it in the if condition.
-
@grant2258 I'm just saying this fix benefits when using analog sticks too but at the cost of cutting the analogs precision to 8 way. That's all. Analog always centers facing to the right and it sucks to play it that way. I know this input cheat is not intended for analog but using it with the analog stick allows you to center facing more properly.
So it got me thinking if we use the off section of our cheat input option to correct analog to stop facing in the direction last pressed too it would complete the driver. It's just a lot more directions to account for on analog.
Cheat Input Off would fix analog and on would fix digital.
I'll never use analog because my cab has digital but it would be cool to see fixed for the benefit of the games emulation.
To correct analog in this hypothetical cheat input off code it would be something like:
if (centered) { return stop_direction;} Else return readinputport(whichport);The stop_direction would be set based on the last position your stick was in before centering. Similarly to what you did to fix digital . Just more directions to account for.
-
you would need to look at that but thats not in the original games specs. The rolling just the eyes is important in analog controls in this game the gimbal lets you walk up to piles of food and throw it all directions without moving because it had such a big throw it would be easy to pull off. I think it would be a sane move to return 7f in digital if your going to switch between the two.
-
@grant2258 agreed.
So is Digital uses 0 to 255, 128 being center and analog uses 00 to FF, 7F being center? Correct?
I'll look into it at a later date. No hurry right now though.
-
nope analog uses 0 - 255 as well the fist 0xff hex is (255 decimal) ff is the mask the second 0x7f is default center value. the min and max are at the end
-
Here's a true control fix for food fight that I'm calling "Live center - rev 3".
Turning on cheat input ports activates the code for analog joysticks without debounce delay. If you're using a digital joystick, you must also turn on grant2258's centering fix which will use the same fix that analog uses but with debounce delay.
Still some things I'd like to edit but I've had enough for today, probably a rev 4 coming soon though when I find more time. I plan to tighten up any dead zones for analog so every possible value is accounted for to be completely accuracy, its fairly close now though. I'd like to eventually implement this into an official driver for the game so it just finally "fixed" once and for all once it's perfect. Credit to grant2258 for his work done in the earlier code versions above that made this possible.
For now though here's the WIP foodf.c driver with fixes implemented:

honestly this was just for digital control hacks you would be better off adding a dipswitch option. with
controls hack -> digital hack controls hack -> analog hack controls hack -> off -
@grant2258 yeah that would be a good idea. Under dip switch we'll have an option.
Live Center - On/Off Use Debounce Delay - No/YesLive centering turns the hack on and off, default being on. Use Debounce Delay adds a delay or not, default being no.

@grant2258
So I don't know how to properly add/ use dip switch options. I added this:PORT_DIPNAME( 0x01, 0x01, "Live Center" ) PORT_DIPSETTING( 0x01, "On" ) PORT_DIPSETTING( 0x00, "Off" ) PORT_DIPNAME( 0x01, 0x01, "Use Debounce Delay" ) PORT_DIPSETTING( 0x01, "No" ) PORT_DIPSETTING( 0x00, "Yes" )Then I need to update my code to something like this but with the right argument:
if ("Live Center dip -> On") // live center dip switch set -> On { // check debounce dip switch If ("Use Debounce Delay dip -> No") t = 0;) // debounce dip set -> No else { t = 8; if (delay > t) delay = 0; } // debounce dip set -> Yes // rest of codeWhat argument do I need to get the dip values for each switch?
-
really dont understand what your doing here at all you dont need debounce for analog ports. I thought you wanted this to work in barcade which is digital you removed that. You would be better removing the cheat port as its not needed since your reading the analog ports again. I really doesnt matter what way you do it if you want it to go upstream you need to enable the original functionality as well.
-
@grant2258 I want dip switches for both so I can decide to use the cheat or not then decide if I want delay or not.
That way I can change the settings on the fly.
If using analog controller
Live center on
Debounce offIf using digital controller
Live center on
Debounce onIf wanting to turn cheat off
Live center off
Debounce offI just don't know how to get the dip switches value to use it in my code
-
// debounce delay for digital if (options.digital_analog) {t = 8; if (delay > t) delay = 0;} if (options.cheat_input_ports) // using cheat ports { if (delay == t) // debounce protection { delay = 0; if (whichport == 0) // x port called { if ( center == 0 ) {} // joy at center, no change else { INT16 temp = readinputport(whichport); // find new x stop direction if (temp > 128) // left { if (temp > 190) currentx = 190; else currentx = temp; } else if (temp < 128) // right { if (temp < 65) currentx = 65; else currentx = temp; } else currentx = 128; // x at center } } else if (whichport == 2) // y port called { if ( center == 0 ) {} // joy at center, no change else { INT16 temp = readinputport(whichport); // find new y stop direction if (temp > 128) // up { if (temp > 190) currenty = 190; else currenty = temp; } else if (temp < 128) // down { if (temp < 65) currenty = 65; else currenty = temp; } else currenty = 128; // y at center } } } else delay++; // return x position if (whichport == 0) { if (center == 0) return currentx; return readinputport(whichport); } // return y position else if (whichport == 2) { if (center == 0) return currenty; return readinputport(whichport); } } else // return original input return readinputport(whichport); }you not using the digital cheatports at all your only reading readinputport(whichport); so there is no need for any setting or delays. enable cheat ports is enough

@grant2258 ok two questions,
If I want to check the value of a dip switch using an if statement how would I do that? It it's on or off?
And I've been using:
INT16 center = readinputport(6) & ~16;To identify my center how do I do that with analog? Just read each port separately or is there an easier check?
Like this:
INT16 center = (readinputport(0) & ~16) + (readinputport(2) & ~16); -
you need to compare 0 and 2 with 7f
if( readinputport(0) == 0x7f && readinputport(2)== 0x7f) center =1;
else center =0;there is no use masking it with wrong bits both axis need checked that why all these checks where done on the original code digital code. Im not quite sure what your trying to achieve here now im sure it will become clear though. Obviously this wont work mainline without an auto center fix for digital to analog controls or other older ports of mame. It will also cause issues if your left right up and down where mapped to dpad and your analog mappings where on the stick. It would make sense to use the same input ports your actually reading
-
@grant2258 thank you,
Ok so I'm adding dip switch options to this instead of using cheat input ports. I added new dip switches to the port list like this not sure if that right or not:
PORT_DIPNAME( 0x01, 0x01, "Live Center" ) PORT_DIPSETTING( 0x01, "On" ) PORT_DIPSETTING( 0x00, "Off" ) PORT_DIPNAME( 0x01, 0x01, "Use Debounce Delay" ) PORT_DIPSETTING( 0x01, "No" ) PORT_DIPSETTING( 0x00, "Yes" )I want to check for that dip switch in my code, how do I do that?
If (dipswitch on) do somethingHow do I specifically check a certain dip switch?
