SDL_GetGamepadAxisFromString

Convert a string into SDL_GamepadAxis enum.

Header File

Syntax

SDL_GamepadAxis SDL_GetGamepadAxisFromString(const char *str);

Function Parameters

const char *

str

string representing a SDL_Gamepad axis.

Return Value

(SDL_GamepadAxis) Returns the SDL_GamepadAxis enum corresponding to the input string, or SDL_GAMEPAD_AXIS_INVALID if no match was found.

Remarks

This function is called internally to translate SDL_Gamepad mapping strings for the underlying joystick device into the consistent SDL_Gamepad mapping. You do not normally need to call this function unless you are parsing SDL_Gamepad mappings in your own code.

Note specially that "righttrigger" and "lefttrigger" map to SDL_GAMEPAD_AXIS_RIGHT_TRIGGER and SDL_GAMEPAD_AXIS_LEFT_TRIGGER, respectively.

Version

This function is available since SDL 3.1.3.
