Unity WebGLA JavaScript API that renders 2D and 3D graphics in a web browser. The Unity WebGL build option allows Unity to publish content as JavaScript programs which use HTML5 technologies and the WebGL rendering API to run Unity content in a web browser. More info
See in Glossary supports Input and InputSystem for gamepads and joysticks for browsers that support the HTML5 Gamepad API.
Some browsers only allow access to input devices after the end user interacts with the device while the application has focus. This is a security measure that prevents the end user using connected devices for browser fingerprinting purposes. For this reason, your application should instruct the user to press a button on their gamepad/joystick before you call Input.GetJoystickNames() to check for connected devices.
The WebGL game controllerA device to control objects and characters in a game.
See in Glossary mapping for the old input system aligns with the W3 spec, where the button mapping layout is shown as follows:
| Buttons | Description |
|---|---|
| buttons[0] | Bottom button in right cluster = CROSS (X) |
| buttons[1] | Right button in right cluster = CIRCLE |
| buttons[2] | Left button in right cluster = SQUARE |
| buttons[3] | Top button in right cluster = TRIANGLE |
Note: As WebGL follows the W3 spec, it might not be consistent with other platforms, and requires unique handling, especially, if you’re targeting multiple platforms simultaneously (for example, Windows and Web).
Unity WebGL doesn’t officially support mobile devices (see WebGL browser compatibility) but it does implement Input.touches and other related APIs in browsers and devices with touch support. By default, mobile devices display a soft keyboard on the touch screen for entering text into UI(User Interface) Allows a user to interact with your application. Unity currently supports three UI systems. More info
See in Glossary input fields. To disable this behavior, use the WebGLInput.mobileKeyboardSupport property.
By default, Unity WebGL processes all keyboard input the web page receives, regardless of whether the WebGL canvas has focus or not. This is so the end user can start using a keyboard-based application without the need to click on the WebGL canvas.
Important: This can cause issues when there are other HTML elements on the page that should receive keyboard input, such as text fields. Unity consumes the input events before the rest of the page can receive them. To have HTML elements receive keyboard input, set WebGLInput.captureAllKeyboardInput to false. When you do this, the application only receives input if the WebGL canvas has focus.
Unity WebGL doesn’t officially support mobile devices (see WebGL browser compatibility) but, for browsers and mobile devices with touch support, Unity WebGL includes support for the following sensors:
Important: Browsers only allow sensor input in secure contexts. This means you must serve the page over HTTPS. The single exception is http://localhost, which you can use during development.
