finite_key_valid

Note

finite_key_valid was added in v0.7.0

The finite_key_valid function checks if a FiniteKey is valid

bool finite_key_valid(FiniteKey key)

Parameters

Type	Description
FiniteKey key	The FiniteKey to check the state of

Code Example

#include <finite/draw.h>
#include <finite/input.h>

FiniteShell *myShell = finite_shell_init("wayland-0");

if (!myShell) {
    FINITE_LOG_FATAL("Unable to init shell");
}

FiniteKeyboard *kbd = finite_input_keyboard_init(myShell->display);

while (wl_display_dispatch(myShell->display) != -1) {
    if (!finite_key_valid(FINITE_KEY_A)) {
        FINITE_LOG_ERROR("Finite Key A is not valid");
    }

    if (!finite_key_up(FINITE_KEY_A, kbd)) {
        FINITE_LOG("A is down");
    }
}

Specification

Developers should ALWAYS call finite_gamepad_key_valid to verify a FINITE_GAMEPAD_KEY’s existence in the internal finite_gamepad_key_lookup table. Just because an enum exists does not mean that the evdev code for that input option is present.

As of v0.7.0, the finite controller hasnt been finished. As such theres been no testing for modular controllers. It’s expected that buttons should work as written, however.
