greetings

So I have gone through all other gamepad related posts on the forum and found that by calling loadGamepadMappings("gamecontrollerdb.txt") it detects my Super Famicom NES-like Controller correctly.

The problem: The DPAD does not work out the box, and I call setGamepadMapping() to foolishly attempt configuring the DPAD. The Down and Right directions seem to work, but Up and Left do not. I suspect because it reports AxisCount of 2, any mappings beyond that are simply ignored.

I am a fan of restrictions when developing games to inspire creativity, but making all my games with only Right & Down movement is a bit absurd. Any tips to point out my mistake is welcome, please!

I ran into issues with the USB MegaDrive controller that came with Sega's MegaDrive Mini from some years back. In order to make the dpad work, I mapped those directions into leftx and lefty, as opposed to dpleft, dpright, etc. So something like:

Code: Select all

-- if megadrive mini controller is detected
local axes = joystick:getAxisCount()
love.joystick.setGamepadMapping(guid, "leftx", "axis",  axes-1 )
love.joystick.setGamepadMapping(guid, "lefty", "axis",  axes   )

And then you'd use LÖVE's love.gamepadaxis callback to check for inputs.

Judging by what your Windows controller test shows, I imagine you similarly need to treat the dpad as axes.

Thanks! I will try this out.
