| This example code looks for the current gamepad state once per frame, |
| and draws a visual representation of it. See 01-joystick-polling for the |
| equivalent example code for the lower-level joystick API. |
| |
| Please note that on the web, gamepads don't show up until you interact with |
| them, so press a button to "connect" the controller. |
| |
| Also note that on the web, gamepad triggers are treated as buttons (either |
| pressed or not) instead of axes (pressed 0 to 100 percent). This is a web |
| issue, not an SDL limitation. |
