Question

map = new BufferedImage[width][height];
  for(int i=0;i<height;i++){
      for(int j=0;j<width;j++){    
  if(charMap[j][i] == Mountains.indentifier) {      
    if ( j+1 < width && j-1 >= 0){
        if(charMap[j-1][i] != Mountains.indentifier && charMap[j+1][i] != Mountains.indentifier) {            
            map[j][i]= tileGrid[1][10];
         }
    }    
    else {
        map[j][i]= tileGrid[8][10];
    }
   }
}

this is the code I’m using to try to check the 2D array by checking each tile around the cell but I seem to be getting a nullpointerexception I’m wondering if anyone can help?

Answer 1

I am suspecting that you are getting the NullPointerException from charMap[j][i] == Mountains.indentifier line.

Make sure that you initialize inner arrays for both charMap and map as suggested by Geoff.
