About moving a sprite with a gamepad

[fabvman]

Hi everyone. I have a little problem. I was reading the tutorials and I want to move a sprite on the screen using the gamepad, but I don't understand how to use joystick input (buffered or unbuffered), I mean, how to take and do something with I trigger some event. Can you give me some orientation about using class input and event?. Thanks!

Hi fabvman.

Gamepad input is handled in the exact same way keyboard input is.

Code: [Select]


const sf::Input& Input = App.GetInput();

if(Input.IsJoystickButtonDown(0, 1))
{
   //do something
}
if(Input.GetJoystickAxis(0, sf::Joy::AxisX < -0.5))
{
   //move my guy left
}


All you have to keep in mind is the first argument for isJoyStickButtonDown() and GetJoyStickAxis() is the controller number. The second argument is which button/axis you are trying to test.

Thanks Epaik, that helps me a lot. But I don't understand why you put < -0.5 as a second parameter of getjoyaxis()

He just forgot a closing parenthesis after "sf::Joy::AxisX".

Good catch.

The reason I did -0.5 is the getjoyaxis function returns an approximate float value for each axis. For example, for a gamepad the x-axis might be ~-1.0 for left, ~0 for nothing pressed, ~1.0 for right.
