Summary Issues

Build Creator verifies your project state on the fly and displays possible errors here. Every issue displayed is either an error or a warning.

Solving Issues

Errors are strict, logical problems. Please resolve them in order to be able to build and upload your game.

Warnings suggest that something is probably wrong in your project, though the raw logic of the project is still valid and you can build the game.


We cannot verify the correctness of your game content. Please check all of your packages twice before building your game.

When you encounter any issues in the Summary window, clicking the issue message should take you to the most probable place to fix it.
