invalid press_threshold {0}, expected [0.0..=1.0]

Error message

invalid press_threshold {0}, expected [0.0..=1.0]

What it means

ButtonSettingsError validation variant: press_threshold was outside the required 0.0..=1.0 range. The press threshold is the axis value above which the virtual button counts as pressed; it must be greater than or equal to release_threshold.

Solutions

1. Clamp press_threshold to [0.0, 1.0]
2. Validate user-provided settings before constructing GamepadButtonSettings
