Mouse Support (Pointer Lock)

This application 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 (this may have to be repeated 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 (this may also have to be repeated a couple of times).

The alias doom also currently maps to this application. In the future, the doom alias may be mapped to another Classic Doom application (different engine implementation) if it is determined to be a more appropriate default.

Properties

The table below contains the properties that are specific to the Classic Doom application. These properties are specified in the props object of a feed item.

Property Type Required Details
game String Yes The choice of game to play (one of the following):
  • doom1 : Doom 1 (shareware version)
  • freedoom1 : Freedoom Phase 1
  • freedoom2 : Freedoom Phase 2

Example

The following is an example of a complete feed that consists of a single Classic Doom application instance (type value of doom). The game property is set to freedoom2 which corresponds to the excellent Freedoom II game developed by the Freedoom project.

{
  "title": "Classic Doom Feed",
  "longTitle": "Classic Doom Example Feed",
  "categories": [
    {
      "title": "Classic Doom Games",
      "items": [
        {
          "title": "Freedoom II",
          "type": "doom",
          "props": {
            "game": "freedoom2"
          }
        }
      ]
    }
  ]
}

This example can be tested by adding a feed with the following URL within the webЯcade player:
