steam_is_overlay_enabled();
Returns: Boolean
When using the Steam API, this function can be called to check
that the Steam client API has the overlay functionality
enabled.
global.steam_api = false;
if steam_initialised()
{
if steam_stats_ready() &&
steam_is_overlay_enabled()
{
global.steamapi = true;
}
}
The above code will set a global variable to true if the Steam client API is correctly initialised, along with the Steam statistics and overlay functionality, or it will set the variable to false otherwise.
