rigidbody2d seems not move very smooth ? :(

Hi,
Sorry for noob.
I have create a very simple game , and I use rigidbody2d, when I give a up force to character.the character jump,but seems not smooth , specially on mobile. help really needed

can you explain this a little better? When you give a up force to character?

Try to turn on Interpolation on the rigidbody. Also make sure you are not moving the transform too of the object, physics + direct transform change doesn’t go so well toghter.
