I’m attempting to rotate a 3D object using Transform.Rotate(), and it does rotate, but it returns to it’s original rotation afterwards.
Here’s my code:
if (Input.GetKey(KeyCode.F))
{
if (inWarp == false)
{
transform.Rotate(0, 180, 0);
}
}
}
It rotates the object, but only until the “F” key is released. Is there a way I can make this rotation permanent?
I’m fairly sure that you at some other point (probably in Update()) manually set the transform (as in transform.rotation = )
transform.Rotate should apply an Rotation to your GameObject which would 1. be permanent and 2. add to the previous rotation. I just tested both. So if everything would be implemented correctly, your GameObject should be rotating constantly and stick to the last rotation you gave it.
One additional Note: If you are not trying to achieve a flip of your GameObject, use Time.deltaTime! (transform.Rotate(0, 180 * Time.deltaTime, 0));
This is the script for the object:

The code is very messy, sorry!
I’m not sure what the problem is, but maybe it has something to do with the movement code above crosshairTexture?
In Line 86 you set the rotation to something based on input, and then in line 255 you set it to something else if the button is pressed. As soon as you stop pushing the button, only line 86 will trigger, that’s why it “jumps back”.
You should consider multiplying rotations instead of setting them. So something like transform.rotation *= Quaternion.Euler(0f, 180f * Time.deltaTime, 0f);
Multiplying them worked 
Thank you!
