PS3 controller left trigger stays pressed on moonlight-embedded

Hello,

I noticed an issue with the PS3 mapping on moonlight-embedded and then I noticed that it was actually using the mappings from here. I already opened an issue on irtimmer/moonlight-embedded but without any answer yet and I thought that it might be better to solve the issue directly here.

The issue is that the left trigger stays pressed after the first time I press it. If I change the mapping, this issue disappears so I think that it comes from an incorrect mapping.

In the current mapping, for the PS3 controller I use () I have these values for the triggers: lefttrigger:a2,righttrigger:a5. It works fine when I change it to lefttrigger:b6,righttrigger:b7.

Here is the mapping that works perfectly: 050000004c0500006802000000810000,Sony Computer Entertainment Wireless Controller,a:b0,b:b1,x:b3,y:b2,start:b9,guide:b10,back:b8,leftstick:b11,rightstick:b12,leftshoulder:b4,rightshoulder:b5,dpup:b13,dpleft:b15,dpdown:b14,dpright:b16,leftx:a0,lefty:a1,rightx:a3,righty:a4,lefttrigger:b6,righttrigger:b7,platform:Linux

Would you like me to submit a PR?

My devices are official PS3 controllers. One came with the PS3 and I bought the second one afterwards. So I guess they should have pressure sensitivity. Then maybe @offalynne was right and it could be an issue with the driver… Honestly I don’t how all this is working together. I never took a look at the code of the driver nor the SDL library… I opened an issue at SDL. I hope someone there will understand the issue and propose a way forward… @CookiePLMonster if you have any idea yourself, do not hesitate to share.

Here is the link to the issue FYI https://bugzilla.libsdl.org/show_bug.cgi?id=4686

I’m not convinced this is a good solution, as it kills pressure sensitivity of triggers. Unless your device is a bootleg gamepad and doesn’t have analog triggers?
