Step 1: Locating prefferences
This is one of the most basic and simplest steps, you will need to go into your construct 2 preferences located in the File drop down menu.
Step 2: Locating Preview options
In this step once you have your preferences open you need to click on the "Preview" tab, and click on the "Preview on LAN Address" more option, it is the "..." at the end of the line.
Step 3: Choose your host address
In this step all you need to do is select your computers network address or your outer ip address depending on how you want it to be.
PS: I whited out my outer IP address so there will be 3 options there.
Step 4: restarting your construct 2
In order to keep these configuration you will need to restart your construct 2 by closing out of it and running it as administrator, and possibly editing your firewall settings.
This is purely for security reasons on the windows os side of things.
Step 5: Testing
Now you should be all set, just click "Run Layout" and you should be all good to go. It will bring the game/application up in a web browser on your end, don't close out of it.
Step 6: Enjoying it over the network
Now you will need to go to another computer or device on your network, open the web browser, and type your network lan IP address with port 50000 into the URL bar, Example: "192.168.1.174:50000"
IF everything worked out fine it should start loading the game over the network to that device, such as it is in the picture loading on a chromebook.
Now it will take longer to load than on a local machine because it is downloading over the network, so be patient.
