i reading in text file consists of grid of alpha-numeric values (see below).

iqqqqq wg2223 s22228 d22223

currently these values looped through , each character sent switch case. switch reads character , outputs given result. code process follows.

private void loadlevel(stream stream) { list<string> lines = new list<string>(); uint width; using (streamreader reader = new streamreader(stream)) { string line = reader.readline(); width = (uint)line.length; while (line != null) { lines.add(line); line = reader.readline(); } } tiles = new tile[width, lines.count]; (int y = 0; y < height; ++y) { (int x = 0; x < width; ++x) { char type = lines[y][x]; tiles[x, y] = loadtile(type, x, y); } } }

in code retrieve text file , store each line in list , loop through each line , extract each character @ given point in grid. rather extract single character extract 2 characters @ same time , pass loadtile function.

as illustration take first line of grid.

i split line 3 strings each 2 characters long , pass loadtile , go on looping through remainder of grid. not know begin effort accomplish task. help appreciated.

well first off you'll propably want alter signature of loadtile loadtile(char, int, int) loadtile(string, int, int). alter calculation of width to

width = line.length/2;

of course of study if line has odd number of characters you'll lose lastly character. additionally if line after first shorter you'll have exceptions , if longer you'll lose additional data.

then can loop through , take substrings.

for (int y = 0; y < height; ++y) { (int x = 0; x < width; ++x) { string type = lines[y].substring(x*2,2); tiles[x, y] = loadtile(type, x, y); } }
