somebody plzz explain to me what I did wrong

Can you explain what are you trying to do? and what error appears on the console?

if its a syntax error, then it could be the spaces on B == 0. it should just be B==0. if its not then idk

undefined label in 34,35,36, and 37. Basically I'm trying to move the map and give an illusion that the character is moving instead when he's not. My info is from petiteprofessor3d, he's on youtube.

look up "smilebasic tutorials- part one" and you'll know what I mean

Ok, now I understand. From what I've seen, the problem is that you haven't defined those labels yet. Also, you should use while/wend instead of goto @loop. Goto can be used for anything but you should avoid using it if there are other commands that do the same (While/Repeat/For/Def).

yeah you need to add the up down left right @'s
