How to move rotated knife(RigidBody2D) diagonally?
Hello, I am new to Unity and so far enjoy my journey. Right now I have accomplished my knife constant rotation within [-30;30] degrees range. However, after the user presses any key, my knife should be moving fast in the direction it currently faces.
How can I achieve the following behavior? I tried addForce, changing velocity, but no results... Perhaps it is even impossible to do? 
Here my knife is facing the left angle and I would like to it to just move in that direction really fast. No fancy effects :)
Here is base position
Here is my source code for the rotating knife:
public void HandleRotation()
{
if (transform.rotation.z >= 0.3f)
{
right = false;
}
else if (transform.rotation.z <= -0.3f)
{
right = true;
}
if (right)
{
begin = begin + 0.05f;
}
else
{
begin = begin - 0.05f;
}
var tiltAroundZ = begin * tiltAngle;
var target = Quaternion.Euler (0, 0, tiltAroundZ);
transform.rotation = Quaternion.Slerp(transform.rotation, target, Time.deltaTime * smooth);
}
Hello.
First, NEVER THINK THIS :Perhaps it is even impossible to do?
Second, about your problem, you have so many ways to move an object in the scene, basicly you have 2 "families" of function, the ones coming from transform, and the others coming from the Rigidbody (if exists)
I dont know whats the propouse of your knife to move so i dont know whichonce is better for your case.
As you are still "noobie" I recommend you to spend some hours reading/watching manuals/tutorials about this: (Dont try to go fast and find the solution to your only problem. A lot of things you dont even know they exists can be shown to you and give solutions you never imagined. Take your time)

Good luck!
Actually it does not matter in my case if it will come from rigidBody or transform. I have attached rigidbody, too. What I care most about is to actually move object to the diagonal direction. I have looked at most of your provided links and have not found any way to move object diagonally, keeping knife end direction.
