Create_Character() check if there is anything wrong plz | |
Did i confuse you? sorry. Maybe I should use smaller words...
Anyway, I found it.
if(usr.V==3) // <-- You need lines after an if statement. for form, see my obfuscating post.See it? Since there isn't anything after the if(), it says there's an error. If the code following the if() is supposed to be inside it (AKA only activated if the conditional returns true) you have to indent it. EDIT: Looking at those input lines, you'll have problems there in the future. You want an alert line - For an alert, the first argument (text) is the question, the second (text) is the box's heading, and the rest (all text) are buttons. switch(alert("[Question]", "[Title]", "[Button1]", "[Button2]")) --Vito | |
Okay...
Optional: For one line after an if() statement you put the line directly after the if(): if(A && (B || C)) return For a few short lines, you enclose them in brackets and seperate them with semicolons ";" similar to what you'd do in C++ or Java: if(A && (B || C)) { usr << "Ha!"; usr.sp --; return; } Not optional: For any number of lines, you just indent once and DM assumes brackets and semicolons: if(A && (B || C)) Does that simplify things? (For simplicity, the third method woreks for any number of lines - you can use it for all three. the other two are to shorten your code.) --Vito | |
okay, okay so how would u fix my problem like write down what would u do because, u confuse me, if i saw u ull confuse me like ur confusing me right now just talking to u confusion king lol
| |
It's not hard. You have two options right now:
A) If the lines after the if() statement are supposed to execue only if, say, V == 1

Rule 0 of posting code: Never use only one space where a tab belongs. Use at least two spaces per tab. Above all else, your code must be readable--particularly because you've obviously got an indentation error.

if(usr.V) //There's that darn indentation error. =/ | |
okay okay big words man, ill i need u to do is to write down the correction not explain how to correct it, i need my game done as soon as possible so i pasted all your confusing good words to study it k, i appriciate for ur help tho
| |
Sorry. forgot the big words thing.
you have: if(usr.V == 1) you need: if(usr.V == 1) Simple enough? Also, note that the shortening of "you" to "u" and other IMer abbrevations are not good etiquette on these forums and you probably should take the time to make your posts (sorry, all you AIM-ers out there) more civilized. --Vito | |
i did but still the same :(
Create_Character() | |
Double-click on the error message. Which line does it highlight?
Note - please use 2-4 spaces to represent tabs, it makes these posts so much more readable. --Vito | |
Oh. That if() statement is indented once two many, as are, I'll bet, all the lines after it. You're not supposed to indent before an if(), only after it.

'untab' the if() statement and probably all the lines 'tabbed-in' to the if() statement.
Note that the words I used in the last few posts were about as 'dumbed-down' as such topics can be. I suggest getting to know programming lingo, as the language of this forum is not "2-bit IM". Also, something to help when someone suggests code you've never heard of - the DM Guide. If someone tells you to use, say, the rgb() function to do something, this will tell you how to use it. It may help with that pseudo-language barrier problem (Whoops, sorry, that's long words...), too. --Vito | |
if(usr.V)otherwise, check to see if V is a defined variable for all mobs and that you aren't using this in a part of the program where usr is null (most procs - New(), Login(), user-defined).
Also, if statements must have following lines, or else it will be an error:
Check all of that.
