Problem description:
Ok so I am a newb to byond code and I was messing around with Zilal's tutorial code (for making a mud) hoping in the process that I would learn something. But (naturally) I keep running into errors. This one I've been working on for forty minutes. Basically every time I attempt to compile, I get this error message "concept_environment.dm:31:error::missing expression" The message is intended for the second line from the last, the line "if(usr.loc = 0) usr.loc = 1" (quotes ate not part of the code line) I know that part of the expression must be missing, but I DID provide the "if" statement along with it's arguments, and a statement to execute if true. SO whats missing?
Edit, Problem Solved
Ok, so I checked the Reference book looked around for like twenty minutes, then noticed operator. Apparently I was making an assignement versus checking a value.
Ex. (wrong)
if(e=e) statement
Ex. (correct)
if(e==e) statement
So for all you newblets out there (like myself), when using 'if' statements and checking for equivalences, Always ALWAYS use TWO '==' equal signs!
if(e=>b) (= are read as is) so that would be "if 'e' is greater than b..."
if(e=<b) if e is less than b...
if(e==b) if e is the same as b...<br/>
