Drawable arrow class.
Arrows behave very similar to lines. They can be used to visualize vectors. This class inherits sf::Drawable and sf::Transformable.

(Default) constructor
| position | Starting point of the arrow. |
| direction | Direction of the arrow (the vector you want to represent). |
| color | The line and triangle color. |
| thickness | The line thickness. |
| static float thor::Arrow::GetZeroVectorTolerance | ( | ) | [static] |
Returns the zero length tolerance.
The tolerance is the bound, below which a vector is considered a zero vector.
| static void thor::Arrow::SetZeroVectorTolerance | ( | float | tolerance | ) | [static] |
Specifies the zero length tolerance.
All arrows shorter than tolerance are represented as zero vectors (i.e. by circles).
