I've watched lots of tutorials but they don't really help me as they are just repeating the same things.
What do you want to know ??
I've done 3d player movement but can't figure out how to do 2d.
What kind of movement?
General movement (jumping, moving etc)
I have watched the brackey's tutorial but it doesn't really make sense, I also can't find out what the unity input system is and how to use it
Also, I don't have enough money to buy a udemy course
So you mean platformer movement? I think there is a platformer controller already in Unity if you import the 2D asset pack.
Yes, I have done that but I cannot understand what they are doing.
