I did what it told me to do, but i have only just started yesterday any ways um..... when i play to see if i did it right my worm(sphere) falls through the floor how do i not make it fall through the floor
you select your sphere and u go to to the top bar to components > physics > sphere collider . hope that helps
do what zeuo said or your ground may be missing a box collider too, be sure that both the sphere and the ground colliders have the IsTrigger checkbox NOT checked too.
and if THAT doesn't work. make sure that you have the sphere above the box collider and not IN the box collider.
