WebPrBoom

WebPrBoom is a fork of the excellent WebDOOM WebAssembly port of PrBoom that was originally developed by UstymUkhman.

The original goal of WebPrBoom was to provide a version of PrBoom that is compatible with the Xbox One (series X/S) browser. Currently, WebPrBoom works well for most devices (including Xbox One) that support WebAssembly and have a physical input mechanism (gamepad, mouse/keyboard, etc.).

Gamepad Controls

The following controls are described using the Xbox One controller.

Equivalent controls for other controller types (PS4, Switch, etc.) should also be compatible.

Name	Controls	Description
Move	D-Pad or Left Thumbstick	Player moves
Run	X Button	Player runs
Fire	A Button	Fire weapon
Strafe	B Button	Strafe when moving left and right
Use	Y Button	Opens doors, etc.
Previous Weapon	Left Shoulder	Select the previous weapon
Next Weapon	Right Shoulder	Select the next weapon
Show Menu	Start + Select	Displays the menu
Show Menu (alternative)	Left Trigger or Right Trigger + Click Left and Right Thumbsticks	This button combo is required due to the Xbox One reserving the Screen and Menu buttons for browser-specific controls. To enter the menu, hold down the left trigger or right trigger and click (press down) on the left thumbstick and right thumbstick.
Controls Menu	Menu Button (Previously start button)	Xbox One Only Displays a menu that allows for choosing between "browsing" and "game" controls.

When presented with a Yes/No prompt, the A button corresponds to Yes and the B button to No.

Note: Screen and Menu Buttons

There appears to be a bug in the Xbox One Edge Browser that periodically prevents the Screen (full screen toggle) and Menu (controls menu) button presses from being processed. If this occurs, click the Xbox button which will cause the left side menu to appear. Next, click the Xbox button again to make the left menu disappear. At this point, the Screen and Menu buttons should work correctly.

Mouse Support (Pointer Lock)

In addition to gamepad support, keyboard and mouse controls are also compatible with WebPrBoom.

It is important to note that WebPrBoom supports Pointer Lock on compatible browsers. Pointer lock binds mouse input to the game window, preventing the game from losing mouse input when the mouse travels outside the window. This functionality is critical when playing a 3rd person shooter. To enable pointer lock, double click on the game window (you may have to repeat this a couple of times). Once the pointer is "locked", the pointer (arrow, etc.) will no longer be visible. To "unlock" from the window, press the escape key (you may have to repeat this a couple of times).
