WEBGL still falls back to CANVAS

[samme]

Version

• Phaser Version: 3.52.0

Description

Create a game with type Phaser.WEBGL. Run it on a device without WebGL. The game runs in CANVAS mode.

The docs say:

Forces Phaser to use the WebGL Renderer. If the browser does not support it, there is no fallback to Canvas with this setting, so you should trap it and display a suitable message to the user.

But this doesn't happen. In this case WEBGL seems to act just like AUTO.

Example Test Code

In Firefox you can set webGL.disabled to false in about:config and then visit any WEBGL example, e.g., http://phaser.io/examples/v3/view/display/alpha/single-alpha. The game runs in CANVAS mode with no error.

Or you can do

new Phaser.Game({
    type: Phaser.WEBGL,
    backgroundColor: 0x0074D9,
    callbacks: {
        preBoot: function (game) {
            game.device.features.webGL = false;
        }
    },
    scene: {
        create: function () {
            this.add.text(0, 0, 'Hello');
        }
    }
});
