In the scene I have a capsule with a camera parented and a looking script so when I look down or up the weapon slightly moves forward and then moves back when I look straight forward.
weapon when I look up or down-
and heres how it looks normally when I look straight forward-
Anyone knows how I can fix that?
EDIT: Here's how it looks in scene view
This is a strange behaviour in Unity's scale inheritance system. If the parent has a non-uniform scale, when you rotate the child, they deform/stretch like a rubber band.
Try adding an empty child GameObject to Player GameObject and parent the Camera GameObject to empty one, and put the rotation script on Camera. This makes parent of the Camera a uniform-scaled transform, so your rotations won't alter childs' scales.
Note: Make sure the empty GameObject has a uniform scale (ie, 1-1-1).
Parent the gun to the player not the camera. The camera movement is changing the transform of the gun. The capsule for the player still tips forward and backwards so parenting it to the player will alleviate the issue. Otherwise you can code a fixed transform that only allows for verticle and horizontal transform change instead of a forward transform change to follow the camera if you don't want to change what it's parented to.
