I created a river and decided to put a sound to that river,but the sound stays the same,no matter how far or how near I am going to the river.I used 3d sound option in game logic in blender game and I did the properties as I saw in a clip on YouTube,but nothing has changed.How can I fix that problem?[![enter image description here][1]][1]
