Aimtrak gun loses alignment when I aim off the screen. <tag> Aimtrak <Tag>

/opt/retropie/emulators/advmame/bin/advm this is a executable file, you call it directly and it will read controller events.
I was stuck trying to understand what js/mouse event it wanted to use.

That is great news, there were a lot of settings there, I would not have thought of this solution.
You're welcome, I'm glad you didn't give up on it.

https://github.com/gunpadawan/gunconf setup util for linux you can set it as a mouse or joystick

Hi dureq,

Out of interest what setting did you find works well?

Did you settle on 25%?

dureq83

25% seemed to work best for my size screen.

@dureq83

Great, thanks.

What size screen do you have? It might then help me to pick a starting point

dureq83

32" LG 720p

I read somewhere that a candle shouldn't be used in place of the sensor bar. Do you think the sensitivity was part of the ambient light in the room?

It looked a lot like the cursor dragging, but thinking about it now, the sensor was probably just identifying to the wrong light sources when it was taken off screen.

Then again the analog setting was a solution so maybe it was drifting while it reached a determined maximum value.

i have a wi mote that easy enough to map up in linux. Ill just need to get a sensor bar ill knock something when i get one. Ill make a bin for testing when i get round to it for people with aimtracks wiimotes doplhin bars ect.

@grant2258
How do you map a wiimote? I have a motionPlus controller so maybe it is just difficult.

If I sync it, it will show up and the buttons are there in jstest, but when I use it is identified as a keyboard in emulationstation and only the directional buttons work.

grant2258

really depends how you configure it and what you want to use it for in my case im only interested in two buttons and the ir sensor

Wiimote.A               = BTN_A
Wiimote.B               = BTN_B
Wiimote.Dpad.X          = ABS_HAT0X
Wiimote.Dpad.Y          = ABS_HAT0Y
Wiimote.Minus   = BTN_SELECT
Wiimote.Plus    = BTN_START
Wiimote.Home    = BTN_MODE
Wiimote.1               = BTN_X
Wiimote.2               = BTN_Y

should get you going not tested it obviously you can change the mapping any way you like

for ir sensor add

Plugin.ir_ptr.X = ABS_X
Plugin.ir_ptr.Y = ABS_Y

I know the ir sensor is working fine i tested it with my remote control just need to get a sensor bar if i ever get round to it

Well ive added light gun support to my wee mame 095 test core its not an official core very much beta for my personal use. when i get a sensor bar ill test it and let mark know if it works or not then he can decide if 2003 and plus will get light gun support if it does.

ok used two ir leds soldered to a usb cable to test the wii more doesnt work well unless you stand in the exact right place every time you defo need the cross hairs on. I dont see how the aimtrack will be much different unless the user uses the gun in the exact same position or calibrates it when the distance/height/player changes. Even changing people with different height would knock this out. Anyone with a aimtrack had much success without cross hairs on?

@grant2258 I think that’s the issue @MrLightgun invented his light gun to solve. But if you have code changes that will make a lightgun of any kind work with lr-Mame2003-plus that would be awesome. I could never get it working right with my dolphin bar/wiimote setup, and in general libretro is way easier to use than advancemame for most people including me.

grant2258

well i dont have a dophin bar ill mess about with the MoltenGamepad looks promising since its using the kernel drivers for the wii mote not the easiest to setup for users though. Ill do some setup tests with this and see if something is doable for the wii mote.

@BJRetro I just got a dolphinbar a few days ago to use with retropie and was able to get T2 to work using lr-mame2003+. I haven't had a chance to test much beyond that yet.

BJRetro

@grant2258 ok I’m sorry I thought you meant you had a breakthrough with getting code working so the wiimote motion and buttons were recognized in a mame core (your own version, and albeit using your own created ir sensor)so that whatever you found in the code might be translated over to the lr-mame2003-plus core. I misunderstood.

BJRetro

@quicksilver interesting I just updated mame2003 plus for something and I think I tried with the wiimote again a couple games and it still didn’t work - wand didn’t move the cursor. Could you try Lethal Enforcers 1 and let me know if it works? If so maybe I have a setting wrong but I had tried a lot to get it working before figuring out I could use advancemame. Separately how did you get past the configuration screen for T2? I was able to configure gun 1 with the wiimote but then it made me try to configure gun 2, which I didn’t have anything for and I couldn’t figure out how to get past that screen to get to the game (in advance mame or mame2003plus).

grant2258

there really is no break through we just need to map the device we want to use for the light gun input. RA does have a lighgun api no documentation of what it maps to and how to map it ect so ill see if there is a workable way for us to map these ir sensor devices

quicksilver

@BJRetro I just had a second controller hooked up to get through the calibration phase for player two. Ill test lethal enforcers when I have a moment and report back.

quicksilver

@BJRetro so I tested lethal enforcers II with mame2003+ and I can get it to partially work but I can only aim in one quarter of the screen and shooting off screen to reload doesn't really work.
