Hi,

i want to build a space ship game in which you rotate your ship by using the mouse and i want to apply a velocity based on the current rotation of the sprite.

First i set a rotation with the following line of code:

gameObject.transform.rotation = Quaternion.Euler(0f, 0f, angleInDegrees);

That works well, but now i have no clue how to apply a ‘force’ to the gameobject in the correct direction.

And i was also wondering why the ‘AddForce’ method does not work with the rigidbody2D, so i want to change it using ‘gameObject.rigidbody2D.velocity’.

Would be nice if you guys could help me out.

thanks

Ok, i have found what is the problem.
I used an vector2 as multiplication, but it has to be an vector3.

Here is my code:

Vector3 velocity = this.transform.rotation * Vector3.up;
gameObject.rigidbody2D.AddForce(velocity);

Thank you guys
