[Solved (properbly)]FloatArray get strange values - Falco-Ger - 26.04.2012

Hi guys,
i am to make a dynamic property system filterscript for a reallife server, but i got some wired problems...

when i read out a float from string with sscanf with the "f" it seems allright. when i print it with printf("%f", value) it shows up correctly.
but when i do something like
new Float:temp = value;
printf("%f", temp);
it shows extraordinary high numbers?!

global:

Код:

#define MAXPROPETIES 100
Float:PropDataF[MAXPROPERTIES][6];

enum
{
	PWORLDX,
	PWORLDY,
	PWORLDZ,
	PINTX,
	PINTY,
	PINTZ
}

in ReadFile(), own function

Код:

while (fread(FHandle,Prop))
	{
		printf("Reading Line %i: %s", i+1, Prop);
		if(sscanf(Prop,"ffffffdddddssssssssss"
											, PropDataF[j][PWORLDX], PropDataF[j][PWORLDY], PropDataF[j][PWORLDZ]
											, PropDataF[j][PINTX], PropDataF[j][PINTY], PropDataF[j][PINTZ]
											, PropDataI[j][PINTID], PropDataI[j][PPRICE]
											, PropDataI[j][PLEVEL], PropDataI[j][PRENT], PropDataI[j][PMAXIN]
											, PropDataS[j][0], PropDataS[j][1], PropDataS[j][2], PropDataS[j][3], PropDataS[j][4]
											, PropDataS[j][5], PropDataS[j][6], PropDataS[j][7], PropDataS[j][8], PropDataS[j][9]
											) )
		{
		    printf ("invalid format in line %i: %s", i, Prop);
		    PropDataB[i] = false;
		}
		else
		{
		    printf ("Property Loaded into memory: ID: %i", j);
		    fwrite(FBackupHandle, Prop);
		    PropDataB[j] = true;
		    j = j+1;
		    if (j >= MAXPROPERTIES)
			{
			    break;
   			}
		}
		i = i+1;
	}

Example Line: 427.896759 2532.036132 16.600128 225.630996 1022.479980 1084.069946 7 20000 2 500 4 Falco NOONE NOONE NOONE NOONE NOONE NOONE NOONE NOONE NOONE
in OnPlayerKeyStateChange (but shouldn't matter where)

Код:

new Float:tempx = PropDataF[i][PWORLDX],
					Float:tempy = PropDataF[i][PWORLDY],
					Float:tempz = PropDataF[i][PWORLDZ];
				printf("temp values are: %f %f %f",tempx, tempy, tempz);
				printf("printing with printf shows %f %f %f", PropDataF[i][PWORLDX], PropDataF[i][PWORLDY], PropDataF[i][PWORLDZ]);

example console output is:

Код:

temp values are: 1137971712.000000 1159627392.000000 1098985472.000000
printing with printf shows 424.142181 2536.166015 16.148437

strangely enough i get this output when compiling, guess thats related to that dump values i get

Код:

...\filterscripts\easyprop.pwn(269) : warning 213: tag mismatch

...\filterscripts\easyprop.pwn(714) : warning 213: tag mismatch

the lines

Код:

269 - GetPlayerPos(playerid, PropDataF[ID][PWORLDX], PropDataF[ID][PWORLDY], PropDataF[ID][PWORLDZ]);
667 - printf("creating 3DText %i for property %i at %f %f %f: %s", Prop3DText[i], i, PropDataF[i][PWORLDX],
												PropDataF[i][PWORLDY], PropDataF[i][PWORLDZ], str);
714 - printf("creating 3DText %i for property %i at %f %f %f: %s", Prop3DText[ID], ID, PropDataF[ID][PWORLDX],
												PropDataF[ID][PWORLDY], PropDataF[ID][PWORLDZ], str);

but no such warnings for things like

Код:

Prop3DText[ID] = Create3DTextLabel(str, 0xFFFFFFAA
												, PropDataF[ID][PWORLDX], PropDataF[ID][PWORLDY], PropDataF[ID][PWORLDZ], 500.0, true);

edit: sorry, that tab layout in the bb code thingy, it's better in my pawno editor
edit2: i guess 2 of theese warnings are because Text3D is no integer i should print with printf, but no static_cast in that c(?) language. anyone know how i can force it cast to integer so that it doesn't give me a warning for such things?

Re: FloatArray get strange values - MP2 - 26.04.2012

Use float() to turn an integer in to a float.

pawn Код:

new myInt = 69;
new Float:myFloat = float(myint);

If you need to turn a string in to a float, use floatstr().
To turn a float in to an integer, use floatround() (rounds up).

Re: FloatArray get strange values - Falco-Ger - 26.04.2012

sscanf should do that automaticaly, doesn't it?
i think the reason for the strange behavior are somewhere else. why do i get the first 3 warnings shown in the compiler output.
any why does printf shows the correct values whereas saving them somewhere else first, and then print it shows something very dump?

i now tripple checked for overwriting arrays out of bounds. found nothing but maybe im just blind.

Re: FloatArray get strange values - Falco-Ger - 27.04.2012

enum
{
a,
b,
c,
ect...
}

just declares variables and initializes them with 0, then 1, 2, 3 and so on? why would i not use enums just like numbers for arrays with names i can remember?
anyway printing those out gives me 0, 1, 2 and so on.
i use 2 enums.
i use 2 arrays because i can not define one array with like 8 integer variables, and then 6 float variables

propdatas is for strings, works good for me

how would you declare an array using enums?
new array[3] creates array[0], array[1] and array[2], i dont get your point

again, what should i do with an enum in sscanf, it's only names for counting numbers
i DO know that pawn is far from c and i hate that
i DO know about warnings, and i can usualy fix them, because i can't in THIS case i am asking you
your link doesn't explain anything about enums, just some kind of printf trick stuff, that i dont need

Re: FloatArray get strange values - Falco-Ger - 27.04.2012

fine then, ill #define those as numbers, i guess when i do so you tell me that everything will work

edit:
wtf... i dont get it but now i know that ill never use enums again...
when they use keywords from c and c++ they should do the same thing for the sake of mankind and sanity

thanks anyway...

Re: FloatArray get strange values - Falco-Ger - 27.04.2012

my identation is allright, the bb code just puts my 4 space tabs from pawno to 8 spaces in the web browser
for long lines i use tabs like this

Код:

FunctionWithAShitLoadOfArguments(ArgumentNameThatIsReallyLong1, ArgumentNameThatIsReallyLong2
                               , ArgumentNameThatIsReallyLong3, ArgumentNameThatIsReallyLong4
                               , ArgumentNameThatIsReallyLong5, ArgumentNameThatIsReallyLong6
                               );

so i dont have to scroll 3 meters to the right to see the code and for reasons of visibility
the rest is ****ed up because i just copy + paste it here and i didn't bother to remove tabs that i put because it's in a control structure like if/for/while/etc
sorry for that, again

anyway thanks for the help.

SOLVED

Edit: why the hell does that have to be on the second page
