Hey I just finished making my 3d game and it seemed perfect at the start when I was the only play testers. Now I asked some of my friends to see if they would test it and they were up for it. This is when I saw the problem. In my game there is a jump strength variable which just makes it how high you jump, its a 3d game first person. In my computer when I play my game to test it, I try to jump to see if I don't just glitch through the roof which I don't but then when my friends (several people) tried out my game, when they jumped it seemed like the variable just doubled because they where jumping way to high and glitching over the ceiling. This isn't just for jumping cus when I walk in the game when playing in my computer I walk at a normal speed (variable=6) but when my friends walk they seem to walk at double the rate. I also tried remote preview and the same is happening just not to me. I don't know if this has to do with the household because I tried my game out it other computers of my household and those computers didn't have the glitch where you jump too high. I don't know why the glitch is everywhere but my own house (or internet). Why might this be happening and how do I fix this?
