(JASS) Trigger shows text 2 times?

12-08-2008, 12:37 PM#1

Hey!

I started with JASS some time ago and wrote my first code now.
The function: It's a simple calculator.
But, of course, it does not work properly. The problem is, that it shows the result two times if one of the 2 numbers is negative and the arithmetic operator is not - .

The syntax and other things are explained at the beginning of the code.

This is the complete trigger:

I don't know what causes that, so I can't have an idea how to fix it.
(Okay, perhaps my warcraft has some errors in it, you may copy it and use it in a test map, as it does not use global variables.)

Thanks in advance,

Your code is sort-of convoluted and hard to read because it looks like half-converted GUI code. You should look at others' code and see how long if-then-else blocks can be re-written, excess parenthesis can be removed, and that sort of thing.

For example:
Collapse JASS:
    if ( SubStringBJ(GetEventPlayerChatString(), c, c) == "^" ) then
        call DisplayTextToForce( GetPlayersAll(), R2S(d)+" ^ "+R2S(e)+" = "+R2S( Pow(d, e)) )
    else
        if ( SubStringBJ(GetEventPlayerChatString(), c, c) == "+" ) then
            call DisplayTextToForce( GetPlayersAll(), R2S(d)+" + "+R2S(e)+" = "+R2S(( d + e )) )
        else
            if ( SubStringBJ(GetEventPlayerChatString(), c, c) == "-" ) then
                call DisplayTextToForce( GetPlayersAll(), R2S(d)+" - "+R2S(e)+" = "+R2S(( d - e )) )
            else
                if ( SubStringBJ(GetEventPlayerChatString(), c, c) == "*" ) then
                    call DisplayTextToForce( GetPlayersAll(), R2S(d)+" * "+R2S(e)+" = "+R2S(( d * e )) )
                else
                    call DisplayTextToForce( GetPlayersAll(), R2S(d)+" / "+R2S(e)+" = "+R2S(( d / e )) )
                endif
            endif
        endif
    endif

//Becomes:
  //local string Display = ""
  //local string Check = ""

    set Check = SubStringBJ(GetEventPlayerChatString(), c, c)
    if Check == "^"  then
        set Display = R2S(d)+" ^ "+R2S(e)+" = "+R2S(Pow(d, e))
    elseif Check == "+" then
         set Display = R2S(d)+" + "+R2S(e)+" = "+R2S(d + e)
    elseif Check == "-" then
        set Display = R2S(d)+" - "+R2S(e)+" = "+R2S(d - e)
    elseif Check == "*" then
        set Display = R2S(d)+" * "+R2S(e)+" = "+R2S(d * e)
    elseif Check == "/" then
        set Display = R2S(d)+" / "+R2S(e)+" = "+R2S(d/e)
    endif
    call DisplayTextToForce(GetPlayersAll(), Display)
Anyway, I think the text is showing up multiple times because the trigger is firing multiple times, due to the events that have been added to the trigger. It will fire once for the negative number (detects a - sign) and once for the other operation. As for the third message, I don't know.

Tried it - that was exactly the problem.
Yeah, it was made out of GUI (c'mon, it's my first JASS trigger!) and I made parts of it shorter, but I forgot the elseifs in the 3rd part.

Ok before I start a new thread, I can also use this old one - it's the same topic anyway.

The triggers work, but I need some comments and/or critics on the coding (simpler solutions somewhere or need of more locals etc.; you get my point).

It is hard to read your code, because you don't use indentation correctly. Look at any script in the resource section to find out how it should be. Secondly, please don't use a,b,c etc. as variable names. The names should describe what the variable is there for. It is very hard to figure out what your code does because of this, and therefore it is hard to give you any advice.

This:
Collapse JASS:
//is this needed? =P
function calc takes real a, real b, string x returns real 
//local real r 
if     x == "+" then
    /*set r =*/ return a + b
elseif x == "-" then
    /*set r =*/ return a - b
elseif x == "*" then
    /*set r =*/ return a * b
elseif x == "/" then
    /*set r =*/ return a / b
elseif x == "^" then
    /*set r = Pow(a,b)*/
    return a^b //should be faster
endif 
return 0
endfunction

For function "constants", just use direct returns (as done above) as well.
Collapse JASS:
call DisplayTimedTextToForce(GetPlayersAll(), 6.00, a)
set a = ""

Use bj_FORCE_ALL_PLAYERS directly instead of GetPlayersAll(), and you don't need to set a to "".

Also, I don't understand this code that much:
Collapse JASS:
    if S2R(S) == I2R(R2I(S2R(S))) then
        set S = I2S(R2I(S2R(S)))
    endif

Well, unless you are trying to compare it to the truncated value.

That's all I could really find at the moment.

Thanks for doing more than just flipping over the code.

return a^b
is not possible, but the others work fine. Thanks.
The part you don't understand is just to check if the real has numbers after the comma
12.200 -> 12 -> 12.000 != 12.200 , display real
but
13.000 -> 13 -> 13.000 == 13.000, display integer

not ModuloReal(a, 1.)==0.
