I have 2 problems. I'm trying to stop infinite jumps. However my player doesn't jump when the gizmo line is slightly sticking out. So I tried to increase the gizmo line and my player starts to jump when I make the gizmo line like 2000 but strangely you'd think my player would jump infinitely because the detection line is so long but he only jumps when he collides with the ground... and also my player loses the ability to jump when I move left or right. Something is really wrong and I hope you can help me. :)
