hi, im working on a pacman clone at the moment and having some trouble getting him to eat. Here is my loadMap function. Im reading 15 X 20 map from a text file and basically if there is not a tile then im going to draw a pellet instead void Map::loadMap(){ fin.open("data/map.txt"); int t, x, y; for(x = 0; x < 15; x++){ for(y = 0; y < 20; y++){ fin >> mapArray[x][y]; t = mapArray[x][y]; if (t != 0) { if (t == 1) tiles[x][y].solid = true; tiles[x][y].block = &blocks[t]; } else { pelts[x][y].dot = &dots pelts[x][y].show = true; } } } cout << "map loaded... " << endl; fin.close(); } my drawMap function just reads from the arrays and draws the proper image. void Map::draw() { int x, y; for(x = 0; x < 20; x++){ for(y = 0; y < 15; y++){ if(tiles[y][x].block != NULL) { tiles[y][x].block->setXY(x*32, y*32); tiles[y][x].block->draw(); } else if (pelts[y][x].show == true) { pelts[y][x].dot->setXY(x*32+12,y*32+12); pelts[y][x].x = x*32+12; pelts[y][x].y = y*32+12; pelts[y][x].dot->draw(); } } } } This all works fine. My problem is with the collision detection. this is what i have at the moment: void collide() { double left1, left2; double right1, right2; double top1, top2; double bottom1, bottom2; for(int x = 0; x < 20; x++){ for(int y = 0; y < 15; y++){ if (pelts[y][x].dot != NULL) { left1 = player.getX(); left2 = pelts[y][x].x; top1 = player.getY(); top2 = pelts[y][x].y; right1 = player.getX()+25; right2 = pelts[y][x].x+8; bottom1 = player.getY()+25; bottom2 = pelts[y][x].y+8; if (bottom1 < top2)return; if (top1 > bottom2)return; if (right1 < left2)return; if (left1 > right2)return; pelts[y][x].show = false; } } } } if i specify a pellet to check for(ex: pelts[2][2]) it will work fine, but trying to check them all with a for loop doesnt work. Any ideas? thanks
