Good points Vanilla.
Thx for answer Rongel, I will keep testing but it s hard to keep track of whats happening sometimes.
I m still curious wether that getcontactdepth means your just as visible to the game as if you were surfaced when above 15 m. doesn t look that way since they stop shooting with peri down but anyways I WANT them to shoot if they spot me but I DONT want them to spot me like if I m surfaced when I sneak silent under the surface
