Example on how to make your Twitch Overlay run a local server to include as browser source inside OBS.
Check the Twitch Plugin for Construct 3.
Install Neutralino CLI tool with
npm install -g @neutralinojs/neu
Export your Construct 3 project as a HTML build.
Unzip the package inside the resources/overlay/ so the index.html is inside resources/overlay/index.html.
Run your project with:
neu run
Compile for distribution with:
neu build
A resources.neu and a binary for each different platform will be generated. To distribute, just grab the resources.neu and pair it with the binary you want to distribute. For example, if you are releasing the overlay for Windows, you can zip the overlay-win_x64.exe and the resources.neu together, both the binary and resources.neu are needed to run the program.
