I have made a simple level editor and I was wondering if there is a way I can export it to some format so that everyone can play the level. Also, since I don’t have much experience in Gdevelop I also want to know how I can do it.
Hello, welcome to the community.
Level editors are extremely complex things because of the amount of data having to be checked and stored.
There is an example built into the engine, and at https://gdevelop-app.com/game-examples-starters/ of a level editor, Including saving and loading. You would need to understand how this one is built and adapt it for your own purposes.
You will then have to adapt the save/load to use filesystem events instead of storage events. Note that filesystem events are not compstible with mobile or browser games, only desktop OSes.
