Get the current state of an axis control on a joystick. Defined in SDL_joystick.h. an SDL_Joystick structure containing joystick information. the axis to query; the axis indices start at index 0. (Sint16) Returns a 16-bit signed integer representing the current position of the axis or 0 on failure; call SDL_GetError () for more information.

Trigger axis values range from 0 (released) to SDL_JOYSTICK_AXIS_MAX (fully pressed) when reported by SDL_GameControllerGetAxis(). Note that this is not the same range that will be reported by the lower-level SDL_GetJoystickAxis().

Get the current state of an axis control on a game controller. a game controller. an axis index (one of the SDL_GameControllerAxis values). (Sint16) Returns axis state (including 0) on success or 0 (also) on failure; call SDL_GetError () for more information. The axis indices start at index 0.

SDL_GameControllerHasAxis(SDL_GameController *gamecontroller, SDL_GameControllerAxis axis); * Get the current state of an axis control on a game controller. * The state is a value ranging from -32768 to 32767 (except for the triggers,

就像 [鼠标输入]和 [键盘输入]一样，SDL也有能力读取来自操纵杆/游戏手柄/游戏控制器的输入。 在本教程中，我们将根据操纵杆的输入使箭头旋转。

2019年12月28日 · TL;DR我试图在我自己的Ctrl+c程序中捕获键盘事件 (更具体地说，是C++命令)。 我正在尝试通过通用键盘按下SDL2。 结束TL;DR我在SO和互联网上找到了关于用SDL2处理键盘事件的链接。 我这里有几个。 https://stackoverflow.com/questions/28105533/sdl2-joystick-dont-capture-pressed-eventhttps://laz.

A SDL_JOYAXISMOTION event occurs when ever a user moves an axis on the joystick. The field which is the index of the joystick that reported the event and axis is the index of the axis (for a more detailed explaination see the Joystick section ).

I've been trying to use a PS3 Sixaxis controller for joystick input, yet it seems that I can't get it to do more than recognize that a controller is plugged in. I've tested the controller in device properties and can move the axis and press the buttons without a problem while getting input.

Get the current state of an axis control on a gamepad. Defined in SDL3/SDL_gamepad.h. The axis indices start at index 0. For thumbsticks, the state is a value ranging from -32768 (up/left) to 32767 (down/right). Triggers range from 0 when released to 32767 when fully pressed, and never return a negative value.
