Drawable arrow class.
Arrows behave very similar to lines. They can be used to visualize vectors. This class inherits sf::Drawable and sf::Transformable.
Determines whether the arrow has a triangle on his endpoint.
| Enumerator |
|---|
| Line |
Straight line without any triangles.
|
| Forward |
Normal unidirectional arrow.

(Default) constructor
- Parameters
-
| 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).
