void smoothHeightMap(int iterations) { int i, j, x, y; float st, sm[8]; for(i = 0; i < iterations; i++) { for(y = 1; y < terrain_y - 1; y++) { for(x = 1; x < terrain_x - 1; x++) { sm[0] = terrain_HeightMap[x-1][y-1]; sm[1] = terrain_HeightMap[x-1][y]; sm[2] = terrain_HeightMap[x-1][y+1]; sm[3] = terrain_HeightMap[x][y-1]; sm[4] = terrain_HeightMap[x][y]; sm[5] = terrain_HeightMap[x][y+1]; sm[6] = terrain_HeightMap[x+1][y-1]; sm[7] = terrain_HeightMap[x+1][y]; sm[8] = terrain_HeightMap[x+1][y+1]; st = 0; for(j = 0; j < 9; j++) { st = st + sm[j]; } terrain_HeightMap[x][y] = float(st / 9); } } } } its supposed to smooth the terrain out by averaging the 9 heights around it and making that the new height. but it causes the terrain to grow miles high after only two iterations. did i make some stupid mistake i can''t seem to find for hours and hours?

i just dont go for the edges, i start at 1 and end at width - 1. in the final, the terrain will be invisible on the edges, and be really tall, to prevent people from driving off into nowhere
