dome

The dome module allows you to control various aspects of how DOME as an application operates.

It contains the following classes:

Platform

Contains platform-specific utilities which may not always be supported.

Static Fields

name: String

Returns the generic name of the operating system or platform, where possible.

time: Number

Returns the integer number of seconds since the unix epoch (1st January 1970).

Process

Static Fields

static args: String[]

Returns a string list of all non-option command line arguments used to invoke DOME’s execution. The first two elements of the returned list will be:

  1. the path and name of DOME’s invokation.
  2. The entry path, combined with the evaluated basepath.

Static Methods

static exit(): Void

static exit(code: Number): Void

Allows you to programmatically close DOME. This command behaves a little differently based on whether an error code is provided (defaults to 0):

  • If code is 0, then this will immediately shutdown DOME in a graceful manner, but no other Wren code will execute after this call.
  • Otherwise, the current Fiber will be aborted, the game loop will exit and DOME will shutdown.

Version

This class provides information about the version of DOME which is currently running. You can use this to check that all the features you require are supported. DOME uses semantic versioning, split into a major.minor.patch breakdown.

Static Fields

static major: Number

The major component of the version number.

static minor: Number

The minor component of the version number.

static patch: Number

The patch component of the version number.

static toString: String

A string containing the complete semantic version of the DOME instance running.

static toList: List<Number>

A list of the version components, in [major, minor, patch] order.

Static Methods

static atLeast(version: String): boolean

This takes a version as a string of the form x.y.z, and returns true if the current version of DOME is at least that of the version specified.

Window

Static Fields

static fps: Number

This is the current frames per second number.

static fullscreen: Boolean

Set this to switch between Windowed and Fullscreen modes.

static height: Number

This is the height of the window/viewport, in pixels.

static lockstep: Boolean

Setting this to true will disable “catch up” game loop behaviour. This is useful for lighter games, or on systems where you experience a little stuttering at 60fps.

static title: String

This allows you to set and get the title of the DOME window.

static vsync: Boolean

Setting this to true will make the renderer wait for VSync before presenting to the display. Changing this value is an expensive operation and so shouldn’t be done frequently.

static width: Number

This is the width of the window/viewport, in pixels.

static color: Color

This is the background color of the window. Note that to this does not affect inside the drawing canvas: use Canvas.cls() to clear the canvas to some color. This field only affects the background color beyond canvas boundaries. Default is black. Cannot be transparent (transparency is ignored).

Static Methods

static resize(width: Number, height: Number): Void

This allows you to control the size of DOME’s window. The viewport will scale accordingly, but the canvas will NOT resize.
