I'm using a mid-point displacement algorithm to generate a map, and the height values are then stored in an array.
The trouble I'm having is loading the numbers back out of the file and into the array when i press F7.
Here's my code for the reader/writer object:
public class Writer {
final int DATA_SIZE = 257;
FileWriter fw;
Scanner sc;
File filename = new File("savedmap.grid");
public void write(MPDGenerator mpd) throws IOException{
fw = new FileWriter(filename);
fw.write("version=1.0 seed="+mpd.RSEED+"\n");
for(int j=0;j<DATA_SIZE-1;j++){
for(int k=0;k<DATA_SIZE-1;k++){
fw.write((int)(mpd.data[j][k]+2000)+"/");
}
fw.write("\n");
}
}
public void read(MPDGenerator mpd) throws FileNotFoundException {
sc = new Scanner(filename).useDelimiter("/");
sc.nextLine();
for(int j=0;j<DATA_SIZE-1;j++){
for(int k=0;k<DATA_SIZE-1;k++){
if (sc.hasNextInt()) {
mpd.data[j][k] = (sc.nextInt()-2000);
}
}
}
mpd.print();
}
}
It doesn't give me any Errors, but doesn't reload the map.
mpd.print(); is the method in the generator which converts the height values into a texture array for the renderer(which uses lwjgl)
the +2000 and -2000 is so it looks neater in the file.
Hmm, is the action behind your F7 key ever executed? Actually we only see the save/write logic. Have you testet if the load function is ever called?
