I updated the template, and here is a small explanation :
The THNK interesting things are included into the extension Multiconnector and the object created attached to it (MulticonnectorGeneralMenu). This extension sadly doesn’t work as a separate behavior-extension yet and I don’t know why, I hope to have it functioning someday (help joyfully welcome). So for now this extension needs to be included into the game itself.)
This extension brings a menu which launches the THNK protocols, with no knowledge required (the aim is to have it available to kids beginning Gdedevelop).
To set this up, you Just need to have the object MulticonnectorGeneralMenu inserted in your main scene, and configure the parameters of the extension MulticonnectorGeneralMenu by double clicking on the object on the scene. there you indicate the name of the game scene which will be started as multiplayer.
and that should be it.
To play, first start a server using the choice, then on an other computer or phone, start the same game and copy-paste the server iP address into the client box provided. then you all play together.
The game controls are arrows to move the car, and mouse to move the cursor… space or ctrl to shoot.
The game to test is here : Multiplayer_Base(with_THNK) _v5 | Play on gd.games
and the code is available here : https://framagit.org/formation-jeux-video/formation-gdevelop/multiconnector-5-full-base-template (the github version is an old one)
