C++ Map Generator

== C++ Map Generator ==

I'm creating a map generator based on Perlin Noise.

First, we need to install the Libnoise Library (https://github.com/qknight/libnoise) as follows

git clone https://github.com/qknight/libnoise
cd libnoise
mkdir build
cd build
cmake ..
make
sudo make install

Once you've done this, you can erase the libnoise folder.

Now, its time to include it to our program:

#include <noise/noise.h>

using namespace noise;

Makefile as an example to show how to include the library while compiling.

CFLAGS = -o
STD = -std=c++11
CC = g++

MG: main.o 
	$(CC) main.o $(CFLAGS) MG.out -I/usr/local/include -L/usr/local/lib -lnoise

main.o:
	$(CC) $(STD) -c main.cpp

clean:
	rm -f core *.o *.out

Once you've compiled, try to execute the binary. It is possible that you get the following error:

error while loading shared libraries: libnoise.so: cannot open shared object file: No such file or directory

It it is the case, do the following:

sudo find / -name libnoise.so
echo $LD_LIBRARY_PATH

if there is nothing to be displayed, add the default path value

LD_LIBRARY_PATH=/usr/local/lib
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/libnoise.so
export LD_LIBRARY_PATH

Then you should be able to run your application.

NOTE: If you are using noiseutils library (http://libnoise.sourceforge.net/downloads/noiseutils.zip), do not forget to include noiseutils.cpp into the main file.

Find below some examples

Here are some mono-color examples

Also, an aplication of this library could be a blood moon generator:
