You're talking about a layout in an exported game? It is in an obscure form so that it both takes up less space and isn't readable by anything but the runtime. It would open a can of worms if we reverse engineered the export to make that possible. There are probably better solutions than doing that
Anyways, if you created both games you could make your own level loader. Basically take a level and output all the object locations and any other stuff relevant to your game to a text file. Then make a parser that reads that said text file and recreates all the objects again.
Hi R0J0hound. Thanks for answering.
Yes. I need to access an exported game layout. I am not using Construct to create the HTML file. I need to call the simple HTML through the C3 game and enable the reverse process (call a new layout in the C3 project using a link in this simple HTML).
