var hostName = window.location.hostname; // Get the full hostname of the current URL
var topLevelDomain = hostName.substring(hostName.lastIndexOf('.') + 1); // Extract the top-level domain (e.g. "com", "org", "edu", etc.)
if (topLevelDomain === 'com') {
// Top-level domain is ".com", set variable to "en"
runtimeScene.getGame().getVariables().get('Lang').setNumber(0);
runtimeScene.getGame().getVariables().get('myVariable').setString('en');
It should detect a top level domain and save “en” to a string if a site has “.com”
