Apply force at angle on X axis in 3D world
Hey guys i recently started with Unity (and C#) and i am trying to pull of a specific drag and shoot mechanism.
As i am figuring it out i am simply to unknown with the whole world axis and i'm not very good with math.
Therefore i can't figure this one out on my own.
The idea is simple. My object is located in a 3D world and i've put in a Joystick. When i drag and release the joystick my "player" object should be shot at the opposite angle. I am trying to do that with a AddForce function.
I do get some results but they are far from what it should be.
To calculate the angle i am using the start point of the joystick ( dead center ) and the position when it's released.
What i think is happening is that my object actually flies in a 3D world while i am trying to let it shoot "2D" style a.k.a. 360 degrees on the x and y axis not on the Z. I simply locked the Z axis on my object.
Long story short, applying a force to my object with the joystick works fine but the angles don't.
This is my code so far:
public void OnPointerUp(PointerEventData data)
{
float anglex = transform.position.x;
float angley = transform.position.y;
float throwAngle = Mathf.Atan2(anglex - m_StartPos.x, angley - m_StartPos.y) * Mathf.Rad2Deg;
Vector3 dir = Quaternion.AngleAxis(throwAngle, Vector3.forward) * Vector3.right;
dagger.GetComponent<Rigidbody>().AddForce(dir * thrust);
Debug.Log(throwAngle);
}
