u/Majestic-Self-3600

i am currently developing my game, and i keep running into this problem where every time i walk i keep bouncing up, i only encounter this problem whenever i use the physics object. the elasticity is set to 0 and it keeps doing that. I have noticed that it only happens after i jump, or do a double jump, it takes a while to wear off for some reason, but it keeps doing this and im trying to have a more stable world. I even set the friction of the backdrop objects to 0 and to 200 and nothing is really working. Does someone know how to fix this?
