Examples

Example 1: Do something depending on the user's operating system.

  print("We're on desktop.")
elseif userPlatform == "ios" or userPlatform == "android" then
  print("This is mobile.")

  print("It's a console.")
elseif userPlatform == "html5" then 
  print("Browser is fine, too.")
end


Example 2: Check if the Steam API has initialized and store the result in a (pre-defined) Visionaire condition called "steamInit". 

local steamLoaded = getProperty("steam_initialized")

if steamLoaded then
  Conditions["steamInit"].Value = true
else
  Conditions["steamInit"].Value = false
end


Example 3: Set the game language to the one we called "Deutsch" in our game settings, if the user's operating system is set to German. Set the game to English in all other cases.
