I keep on getting this error:
Harry Potter.dm:4: error: if: expected end of statement
for this code:

mob
verb
Attack(var/mob/M in oview(1))
var/DAMAGE=rand(usr.strength/4 - m.defense/2, usr.strength/2 - m.defense/4) + rand(usr.strength/4 - m.defense/2, usr.strength/2 - m.defense/4) if (DAMAGE > 0) M.HP -= DAMAGE

what did I do wrong?

Your if() statement needs to go on the next line down; you have it on the same line where var/DAMAGE is assigned. To make that work, you either need to put a semicolon after the end of that assignment, or move if() down a line.

Just makes it worse:
Harry Potter.dm:4:error:usr.strength/4:undefined var
Harry Potter.dm:4:error:m.defense/2:undefined var
Harry Potter.dm:4:error:usr.strength/2:undefined var
Harry Potter.dm:4:error:m.defense/4:undefined var
Harry Potter.dm:4:error:usr.strength/4:undefined var
Harry Potter.dm:4:error:m.defense/2:undefined var
Harry Potter.dm:4:error:usr.strength/2:undefined var
Harry Potter.dm:4:error:m.defense/4:undefined var
Harry Potter.dm:5:error:DAMAGE:duplicate definition
Harry Potter.dm:5:error:0:duplicate definition
Harry Potter.dm:5:error:> :instruction not allowed here
Harry Potter.dm:5:error::empty type name (indentation error?)

Harry Potter.dm:5:error:DAMAGE:duplicate definition
Harry Potter.dm:5:error:-= :instruction not allowed here
Harry Potter.dm:5:error::empty type name (indentation error?)



this is the code when that is done:

mob
verb
Attack(var/mob/M in oview(1))
var/DAMAGE=rand(usr.strength/4 - m.defense/2, usr.strength/2 - m.defense/4) + rand(usr.strength/4 - m.defense/2, usr.strength/2 - m.defense/4)
if(DAMAGE > 0) M.HP -= DAMAGE

No. What it's doing is exposing errors that were there already, but weren't showing up because of another error.

Harry Potter.dm:4:error:usr.strength/4:undefined var

Is there a var/strength line listed for mobs? It's not in the code segment you gave us. If you don't have this var defined, you need to define it.
mob
  var/strength

Harry Potter.dm:4:error:m.defense/2:undefined var
You're looping through var/mob/M, not var/mob/m. The lowercase m is an undefined variable. You should be using uppercase.

I think all the other errors hang off those two, but it'll be easier to tell for sure when you've fixed those.

what is wrong now?

mob

Hrm. It occurs to me now that that badly indented var/DAMAGE line wasn't you trying to fit it on the forum, but was in fact you messing up the indentation.

That line, and the one below it, has to be indented beneath the verb definition. By unindenting it all the way over to the left margin, BYOND thinks you've left the verb and you're now defining a global var.

Ok here it is now:

mob
var/strength


mob
verb
Attack(var/mob/M in oview(1))
var/DAMAGE=rand(usr.strength/4 - M.defense/2, usr.strength/2 - M.defense/4) + rand(usr.strength/4 - M.defense/2, usr.strength/2 - M.defense/4)
if(DAMAGE > 0) M.HP -= DAMAGE


Harry Potter.dm:8: Inconsistent indentation.

You've got spaces and tabs mixed for your indentation. This is the one major no-no of BYOND. Use a single tab or a set number of spaces for every indent, like this:
mob
  verb
    Attack(...)
      var/DAMAGE = ...

Your indentation may look correct, but it's not.

Now what?:


mob
var/HP
var/MP
var/strength
var/defense





mob
verb
Attack(var/mob/M in oview(1))
var/DAMAGE=rand(usr.strength/4 - M.defense/2, usr.strength/2 - M.defense/4) + rand(usr.strength/4 - M.defense/2, usr.strength/2 - M.defense/4)
if(DAMAGE > 0) M.HP -= DAMAGE

Harry Potter.dm:14:error:rand:undefined proc

Now the line with the if() is indented too far. It should be at the same indentation level as the line before it.
