I say rotate around Z, Unity rotates around Y

I tell unity to spin around the Z axis but in the engine it stil rotate around the y Axis. rotating around the Y and X axis isn’t a problem.

Note: Localrotation and rotation doesn’t make a diffrent.

here is the part code that does the spinning.

yRotation += Input.GetAxis(“Mouse X”) * lookSensitivity;
currentYRotation = Mathf.SmoothDamp(currentYRotation, yRotation, yRotationV, lookSmoothDamp);
var Rotate: Vector3;

		if(place== "y"){
		
			Rotate= Vector3(0,currentYRotation,0);
		
		}
		if(place== "-y"){
		
			Rotate= Vector3(0,-currentYRotation,180);
		}
		
		if(place== "x"){
			
			Rotate= Vector3(currentYRotation,0,270);
			
		}
		
		if(place== "-x"){
		
			Rotate= Vector3(-currentYRotation,0,90);
			
		}
		
		if(place== "z"){
		
			Rotate= Vector3(90,0,currentYRotation);
		}
		
		if(place== "-z"){
		
			Rotate= Vector3(270,0,-currentYRotation);
		}
		
		
	
	
	transform.rotation= Quaternion.Euler(Rotate);

It going to rotate around its local rotation. If it has already been rotated it will change all the axes.

It is an easy fix.

Replace

transform.rotation= Quaternion.Euler(Rotate);

with the function call:

transform.Rotate(eulerAngles : Vector3, relativeTo : Space = Space.Self)

In the first parameter you want your vector, and in the second

you want it relative to Space.World instead of Space.Self.

Quaternion.Euler() rotates like a tank barrel: global Y, then local X (elevation) then local Z (spin the barrel to look cool.) That 270 on X rotates so old forwards is up. Then the currentYrotation spins local Z, which is now Y.

I can’t think of a way to do it using just Vectior->Quat like you have, but if you have the ifs all compute quaternions, this works: Quaternion face = Quaternion.Euler(0,0,currentYrot) * Quaternion.Euler(270,0,0);. Same math, but forces the Z rotation to go first, so be on global Z. Ends with: transform.rotation = face;
