My Code that Works on an object's rotation doesn't work.
I'm coding a system, where if my 3d object moves forward, it's rotation goes down to a certain point, when I try my code, it will keep rotating for ever when I use it (pressing W).... Code:
if (Input.GetKey(KeyCode.W))
{
transform.Translate(0f, 0f, speed * Time.deltaTime); // Forward movement of the player's character.
if (transform.rotation.x <= 20) //If the rotation of the object is below or = 20, make the rotation higher
{
transform.Rotate(rotationSpeedWhileMoving * Time.deltaTime, 0f, 0f);
}
}
else if (transform.rotation.x > 0) //Returns THe object's rotation to 0
{
transform.Rotate(-1 * rotationBackwardsSpeed * Time.deltaTime, 0f, 0f);
}
transform.rotation is a QUATERNION, you should not try to read and write values of it, unless you really know what you are doing, and it clearly seems that it's not the case.
You should check against transform.localEulerAngles instead, which are the values displayed in the inspector:
if (transform.localEulerAngles.y <= 20)
// ...
if (transform.localEulerAngles.x > 0)
No, change transform.rotation.x to either transform.rotation.eulerAngles.x or transform.localEulerAngles.x.
transform.eulerAngles is the global rotation of the object.
transform.localEulerAngles is the local rotation of the object, the values shown in the inspector.
What is the difference between local and global rotation?
Good day.
As @Hellium says, in Unity, standard variable for rotation are QUATERNION (there are not the "typical" 3 rotation of each axis). In the inspector, you see the EULER ROTATION (not quaternion), so if you want to manipulate rotation, you should do it via Euler angles (they are indeed the 3 axis rotation from 0 to 360).
You should check against
transform.localEulerAngles
instead:
Go try it, and if don't suceed, come again!
Bye!
This is where I'm stuck now
if (Input.Get$$anonymous$$ey($$anonymous$$eyCode.W)) { transform.Translate(0f, 0f, speed * Time.deltaTime); // Forward movement of the player's character.
if (transform.localEulerAngles.x <= 20) // Transforms the rotation of the object a bit down.
transform.Rotate(rotationSpeedWhile$$anonymous$$oving * Time.deltaTime, 0, 0);
}
else if (transform.localEulerAngles.x > 0 && transform.localEulerAngles.x < 40) //returns the rotation back to normal.
transform.Rotate(-rotationBackwardsSpeed * Time.deltaTime, 0, 0);
the 'else if' part works fine, but the if inside the if statement doesn't work at all.
The problem I see with your code is that when the rotation reaches 20 degrees, the if is evaluated to false, and the else block is ran, thus, the object rotates back to a value less than 20 and the if is ran the next frame, the object rotates a little bit and the process repeats : else is ran, if is ran next frame, else, if..... again and again....
