Hi everybody! I'm trying to learn the basics of unity and decided to go throw the "2DGamePlatformGuide". When I downloaded the .zip file called "2DGameplayTutorial" and opened the scene called "2DPlatformer" (like how it said on the tutorial .pdf file) on unity, it didn't show the objects inside the scene. The objects were listed on the hierarchy, but when I selected them I would only see the y,x and z axes for controlling the object. I did not see the level, like the one on the .pdf file, instead I saw the symbols representing lights and sound and if I would select e.g. a crate from the hierarchy, I would see a green lines from the crates corners. Whenever I would click on something else, this crate would disappear. Did I do something wrong? Because like I said I am new and might have made a silly mistake somewhere.
