Need a c++ Coders Help =D
« on: December 13, 2014, 03:49:01 pm »
I love AllOcean3.0, I just have one problem with it.... It does what it is suppose to do, just it leaves some cracks up against the land where its empty space and water missing. To fix this I want AllOcean3.0 to fill in from a height of zero where there is land plus 1 chunk into the land.

Basically how do I make it fill 1 chunk in further then what it does. Here is the code below

Code: [Select]
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>

#define DESCRIPTION "Fills the ADT with ocean 3.* style where no terrain is above 0."
#define ARGUMENTS "<map filename> [<depthfactor>]"

#define USAGE( minimumArguments, argc, argv )
if( argc < minimumArguments + 1 )
{
printf( "  %sn", argv[0] );
printf( "    " DESCRIPTION "nn" );
printf( "    Usage: "%s " ARGUMENTS ""n", argv[0] );
printf( "    Built at: " __DATE__ "n" );
return -1;
}

unsigned int Offset;

};

};

delete File;
}


I am not a coder just to say right off which is why I am asking on the forum, I can compile this just fine and it works fine, just want to make that tiny edit to it.

Any help would be greatly appreciated =D

The error is in here:

I still can't seem to figure out what the error is (math is really not my strong suit, which for a coder seems to be a must .../hits head on metal beam). So I give lol, could you be a little more precise on what the error is :P?

Been tinkering with that section of code ever since you answered and still a no go :(

Look closer, it's staring you in the face.

I have tried so many different variations of this section of code for over a month no that I couldn't even tell you which ones I have and have not tried. (except for the correct one of course lol).

The one I do remember is that

if((baselevel - getHeightValue2(j*8+k)) >= baselevel
                 || (baselevel - getHeightValue(j*8+k)) >= baselevel
                 || (baselevel - getHeightValue(j*8+k+1)) >= baselevel
                 || (baselevel - getHeightValue((j+1)*8+k)) >= baselevel
                 || (baselevel - getHeightValue((j+1)*8+k+1)) >= baselevel  )

is suppose to be

if((baselevel - getHeightValue2(j*8+k)) >= baselevel
                 || (baselevel - getHeightValue(j*8+k)) >= baselevel
                 || (baselevel - getHeightValue(j*8+1+k)) >= baselevel
                 || (baselevel - getHeightValue((j+1)*8+k)) >= baselevel
                 || (baselevel - getHeightValue((j+1)*8+1+k)) >= baselevel  )

I think anyway lol. So if I want to change what it does do I change

if((baselevel - getHeightValue2(j*8+k)) >= baselevel

to one of the 4 options below it?

example if((baselevel - getHeightValue((j+1)*8+1+k)) >= baselevel

or am I WWAAAYYYYYYYYY of base here lol?

Way off, you're not looking close enough.

Try this look at the rest of the code and then go back and compare and see if you can notice anything missing.

Tell people what's wrong or shut up, thanks. Tbh, I don't even know what is wrong myself, else I had fixed it years ago.
