| I'm trying to make a small game, since I need training in C++ programming. However, what's a game without levels? Therefore, I need code which reads the level data from a file. (using fstream.h) ifstream is; is.open ("c:\\ZRO_lv.txt"); for (int yy=1;yy<26;yy++){ for (int xx=1;xx<61;xx++){ if (!rep){ is.get(rep); is.get(readblk); is.get(readcol); }else{rep--;} map[xx][yy].chr=Blockchar(readblk); map[xx][yy].col=readcol; } } is.close(); (File format, in case somebody wonders: Byte 1 = How many times to repeat the two following bytes. Byte 2 = Block number. Byte 3 = Block color) However, for some reason, something goes wrong when it comes across a 0x0A byte, which seems to cause it to read junk instead of file data. Can anyone tell me what the problem is? (edited by Smallhacker on 09-05-05 12:31 PM) |

| You've opened it in text mode. 0A is a newline character, so it may be converting it to 0D0A or something like that. I'm not sure how to open it in binary mode, though, since I just use fopen(). Also, I wrote a program like this and I found I had to do map[y][x] = blah. |

| Just do is.open("c:\\ZRO_lv.txt", ifstream::binary); That should work  |
