is it only going through certain block types?
Any errors / warnings showing in console.
Walk through the mechanics of what should be happening, and check each step against what is within the vid), going to be a process of logical steps to what should happen against what is happening, like…
Is the collision being registered with the brick and ball. if not break that part down first.
does the brick take damage. if not why
etc
or have a run through collision detection with the bricks section again. follow it through and see if anything has changed, I know that sometimes when you upgrade mid project it messes up the tag assignments sometimes.
Just as a bit of advice for future, I would say its best to complete a project first before upgrading the editor.
That way it will be consistent throughout that projects lifetime, and once you upgrade the version you have a clean slate for starting the next project.
(done it myself, once and once only, as it caused numerous head scratching hours to go back and resolve)
