A Renderer drawing particles as lines for the SFML 2D rendering engine.
the length of the lines is function of the Particle velocity and is defined in the universe space while the width is fixed and defines in the screen space (in pixels).
The width can be zoomed with the View using resizeMode (either SPK_SFML::RESIZE_ZOOM_X or SPK_SFML::RESIZE_ZOOM_Y). However the maximum width for a line is constraints by the hardware.
Below are the parameters of Particle that are used in this Renderer (others have no effects) :

float | width = 1.0f , |
|||
ResizeMode | mode = RESIZE_NONE | |||
) |
Constructor of SFMLLineRenderer.
length | : the length multiplier of this SFMLLineRenderer | |
width | : the width of this SFMLLineRenderer in pixels | |
mode | : the resize mode of this SFMLLineRenderer |
virtual bool checkBuffers | ( | const Group & | group | ) | [protected, virtual] |
checks the buffers and prepare them
This method has to be implemented in derived class that uses buffers.
true must be returned if the buffers are found and initialized, false otherwise.
group | : the group in which to check the buffers |
Reimplemented from BufferHandler.

ResizeMode | mode = RESIZE_NONE | |||

Creates and registers a new SFMLLineRenderer.
length | : the length multiplier of this SFMLLineRenderer | |
width | : the width of this SFMLLineRenderer in pixels | |

virtual void createBuffers | ( | const Group & | group | ) | [virtual] |
Creates the buffers for this buffer handler in the given group.
If the buffers for this type of buffer handler already exists within the Group, they are priorly destroyed.
The type of buffers created depends on the state of the buffer handler at the time this method is called.
This method has to be overridden in derived classes that use buffers
group | : the Group in which to create the buffers for this buffer handler |
Reimplemented from BufferHandler.
virtual void destroyBuffers | ( | const Group & | group | ) | [virtual] |
Destroys the buffers for this buffer handler in the given group.
if the buffers dont exist, nothing happens.
This method has to be overridden in derived classes that use buffers
group | : the Group in which to destroy the buffers for this buffer handler |
Reimplemented from BufferHandler.
ResizeMode getResizeMode | ( | ) | const |
Gets the resize mode of this SFMLLineRenderer.
