steamworks.canShowOverlay

Overview

This will be true if Steam overlays can be shown on top of the app. This means that Steam popup notifications can be shown and screen overlays can be shown via this plugin's APIs or by the user pressing the default Shift+Tab keys.

Gotchas

This property will be false in the following cases:

• A valid appId was not set in config.lua as documented here.
• The steamworks.isLoggedOn property is false, indicating that the application is not currently connected to the Steam client.
• The Steam client is not currently running.
• User has disabled overlays in the Steam client's In-Game settings screen.
• During the first few seconds of app startup. This is normal behavior since the Steam client needs time to bind to the application process.
• On Mac, the application (such as the Corona Simulator) was not launched from the Steam client, or a required system preference setting is missing. See the Overlay Troubleshooting guide for more details.

Example

local steamworks = require( "plugin.steamworks" )

print( "Can Show Steam Overlay: " .. tostring(steamworks.canShowOverlay) )
