This lecture finally exposed a fundamental flaw in this game’s design.
Having the character always centered and moving the map itself might work in some specific cases, however this approach is extremely limited and forces students to follow exactly the same steps as the teacher including copying the screen resolution.
I took the liberty of drawing and planning for a 1280x720 resolution, but it’s all ruined. Look at the huge amount of unuseable area.
In other words, this approach is not very customizeable and extremely limited for replication in real development scenarios. You might consider creating more customizeable projects for a possible updated version of this course.
