Hi I was working on a kha game project in Kode Studio and added gamepad support to it .After coding everything is working fine ,the gamepads are working properly in debug mode .But when I compiled the code to native Mac app, or Linux app the application is not taking input from
the game pad.

If some body has come across such issues before then please help

I'm troubleshooting the same problem but am getting nowhere. There is a suspicious line commented in Kore/Input/HIDManager.cpp for macOS system backend:

https://github.com/Kode/Kore/blob/77b53baf3db139469ecbfb96bd14c71ce9b50661/Backends/System/macOS/Sources/Kore/Input/HIDManager.cpp#L142

I can see the log entry on line :146

https://github.com/Kode/Kore/blob/77b53baf3db139469ecbfb96bd14c71ce9b50661/Backends/System/macOS/Sources/Kore/Input/HIDManager.cpp#L146

But since no actual HIDGamepad is instantiated, I obviously don't get any callbacks for changes in axis or button state on the physical gamepad.

Totally new to Kha so not sure where to go next.

Thank u Greger ,
I am also new to Kha,I tried it in Linux also but still having the same problem.let me check those codes you mentioned ,if I have some luck.

Did a new C++-build now and double checked my gamepads in various tools and for some reason it is working for me now:

Output from log.

Add gamepad: Vendor: Logitech, Name: Xbox 360 Wired Controller
HID device plugged. 1 gamepad(s) connected.

Add gamepad: Vendor: Sony, Name: PLAYSTATION(R)3 Controller
HID device plugged. 2 gamepad(s) connected.

I haven't changed any code in Kha. Running macOS High Sierra with a fresh Xcode install.

Still doesn't work for me in Krom though.

Mac gamepad support is very complicated because macOS itself does not support gamepads. Kha circumvents that by reading gamepad data on the usb protocol level but that doesn't support Xbox gamepads because they do not follow the usb hid gamepad protocol.
Linux gamepad support uses /dev/input/js0 and should work if your Linux distribution supports your gamepad.
Both of you please set some breakpoints and see what happens in Kore/Backends/System/(macOS or Linux)/.../(HidGamepad or Gamepad).cpp.
Krom probably needs a recompile.

Thanks for the info. Like I mentioned, my C++ build actually started working fine. I use https://github.com/360Controller/360Controller/releases to be able to hook up my Logitech controller which appears to work fine in Godot and now Kha/C++.

I'm trying out Armory 3D which bundles Kha and Krom with uknown versions (don't know when they were built). I cloned and built the latest version of Krom and replaced the Krom.app bundled with Armory but it seems it is not compatible with the bundle version of Kha:

Trace: TypeError: Krom.lockVertexBuffer is not a function
    at $hxClasses.kha.graphics4.VertexBuffer.lock (krom.js:30902:21)
    at $hxClasses.kha.graphics4.ImageShaderPainter.initBuffers (krom.js:29082:102)

    at Function.Main.start (krom.js:197:13)
    at Function.Main.main (krom.js:161:7)
    at krom.js:34698:6

So I'll go ahead and try to update Kha as well for Armory 0.5 and see if it helps.

Thanks for your input.

How to do the cpp build

@robert
In Mac gamepad is working for Godot engine ,but why not for kha.Please tell me about how to recompile kha kore or krom so that gamepad will work

I already explained the situation. To compile a Kha application just run "Kha/make --compile".
