Movement script help

I added a script to my game for making a movement of player

this is the errors

I get
this is for camera
Assets/Scripts/camera.js(42,13): BCE0144: ‘UnityEngine.Component.rigidbody’ is obsolete. Property rigidbody has been deprecated. Use GetComponent() instead. (UnityUpgradable)

This is for movement

Assets/Scripts/movement.js(99,24): BCE0144: ‘UnityEngine.Screen.showCursor’ is obsolete. Property showCursor has been deprecated. Use Cursor.visible instead (UnityUpgradable) → UnityEngine.Cursor.visible

Just do exactly what the errors say - you can’t just do .rigidbody anymore, you have to do a GetComponent(Rigidbody), and rather than using showCursor, instead set Cursor.visible to true or false.
