This adds the ability for games to obtain platform-specific information about joypads such as their vendor/product ID, their XInput gamepad index or the real name of the device before it gets swapped out by the gamecontrollerdb's name.
This PR also includes a rebased version of #76045, this is because this PR is intended to be mainly to help people implementing Steam Input, as having the gamepad index is essential.
During GDC and general testing on Steam Deck units, we found that single
gamepads would often register inputs twice under certain circumstances.
This was caused by SteamInput creating a new virtual device, which Godot
registers as a second gamepad. This resulted in two gamepad devices
reporting the same button presses, often leading to buggy input response
on games with no multi-device logic and other-wise could cause intended
Steam rebindings to not work as intended (for example, swapping o and x
on a playstation pad if that feature isn't supported by the game.)
SDL gets around this by taking in a list of devices that are to be
ignored. When valve sees a controller that wants to be rebound via
SteamInput, they push a new VID/PID entry onto the environment
variable `SDL_GAMECONTROLLER_IGNORE_DEVICES` for the original gamepad
so that all game inputs can be read from the virtual gamepad instead.
This leverages the same logic as we are already using SDL gamepad
related HID mappings.
Previously if an action was both pressed and released on the same tick or frame, `is_action_just_pressed()` would return false, resulting in missed input.
This PR separately the timestamp for pressing and releasing so each can be tested independently.
The `InputEvent` class currently supports the `pressed` and `released` states, which given the binary nature, is represented by a `bool` field.
This commit introduced the `CANCELED` state, which signals that an ongoing input event has been canceled.
To represent all the states, the `InputEventState` enum is added and the `InputEvent` logic is refactored accordingly.
* Description of `ui_text_submit` action should be "Submit Text" instead of "Text Submitted".
* Spell out "Animation" instead of using "Anim.".
* Treat "Max" as regular word instead of writing "Max.".
* Use generic "Set %s" for action name instead of a dedicated "Set target_position".
* Add translator comment for:
* "Inclusive" and "Self" in the profiler.
* Places where it needs the context about being an editor progress label.
* "Duplicated Animation Name" since it's refering to the new name of a duplicated animation.
* Disambiguation of "View Plane Transform", "Paste Selects" and "Display Normal".
* Fix wrong undo action name for renaming an input action.
* Fix missing end quote in a shader error message.
* In class reference:
* Fix duplicated "if" in the description of `signf()`.
* Fix mismatched example output in `String.operator %()`.
* Fix typo in the description of `Decal.texture_emission`.
* Unify description of `String.match()` and `StringName.match()`.
Some internally created emulated/instantiated events didn't have a
device id. This PR sets for these cases a device id.
Also rename `DEVICE_ID_TOUCH_MOUSE` to the more generic
`DEVICE_ID_EMULATION`.
