Using other input devices

[albfan]

Out of curiosity dig a bit on gamepad and add this patch:

Which outputs:

trigger : False

joystick3 : False
joystick4 : False
joystick5 : False
joystick6 : False
joystick7 : False
joystick8 : False
joystick9 : False

Axis.throttle : 0.9990224828934506

I'm sure ursina tries to stay simple, but wonder if support other devices would be an accepted PR.

Same as buttons remap, it can accept a map for button names and axis names and send that data as gamepad.py does to input function.

Basically adding this into my own main.py for a project was able to read my wheel axis and buttons:

I suppose a generic joystick would be a better name for any device with axis and buttons

I found a problem with current input handler, it tries to filter the " up" movement for a button, but ends filtering any key ending in "up"

I open a PR #524

[albfan]

By now I I call my hat up hap instead of hup

[albfan]

Showing a use case for this change: Allow to use a wheel for a drive game (still only hat, not axis, but input is there to code some logic)

@albfan : I wonder weather this patch might be required to set-up the FirstPersonController so that it is moved by scrolling mouse wheel 🤔

[albfan]

This help yo recognize other input, so with modification you can use whatever input, and then write some logic around that

[vvvvvvitor]

You should make a PR if you've got something working and it's stable.

[albfan]

Ok, will try to code some PR to cover devices with axis and buttons
