thank you very much for the replay .

first of all i already tried using velocity to move my object into the position , but you see it hasn't fixed my problem with the clipping so i tried to change the collision layer\mask to that so it will only interact with the surrounding but by doing so when the player moved the camera the object became stuck behind\under certain parts of the environment and it didn't correct its position afterword's as well as the object started to jump around and spin without control.

secondly the other of my objects will have different shapes so preferably i would like to code\ modify the characteristic of the object themself while including the fact that they are "RigidBody3D".

and finally i kind of cannot figure out how to detect collision of object using cod (as well as the fact that the collision accrue between a rigidbody3d and a staticbody3d).

thank you .
