this is my code, and the Console is saying some errors
The best overloaded method match for `UnityEngine.Vector3.this[int]' has some invalid arguments
Argument `#1' cannot convert `ConstraintRotation.ConstraintAxis' expression to type `int'
The best overloaded method match for `UnityEngine.Quaternion.AngleAxis(float, UnityEngine.Vector3)' has some invalid arguments
Can someone help me? It's a script to Constraint X rotation of the main camera.
