I finished this section of the course. However, I have not been able to export the game.
I noticed my file is a little larger than the instructor’s file. And, I remember I have the level scene saved twice in two areas. I don’t know if that is effecting the export. When I press play, a blank screen comes up. If i hit the run current scene button, the game will play. I can play it within Godot. When I double click the .exe file i get the blank screen.
After clicking the Run Project (F5) Play The Project.
as Six_Dots_Software shows if you go into the Project > and Project Settings
if you make a note of where the scene that works when you play current scene is saved.
in that Run settings. you can click the white folder to the right and it will let you browse the project and you need to select the level scene that is working.
as that run says what scene initially run when you press play.
I had a look at your last project you uploaded, you have the player seen as the main scene to run when you press F5 or the play button, thats why your getting the grey screen.
We do have a 2D 'Master Mobile Game Development with Godot 4: From Concept to App Stores
That’s just been released yesterday.
Might be worth looking at the curriculum and the promo video to see what’s involved. It’s kind of a beginner + course.
Exporting to mobile uses a few extra techniques and the 3d games we make in this 3d course would take a few changes to get them to work on mobile devices.
