Public Attributes
float	Delay = 0.05f
	Delay between applying a swap to produce a trail.
float	RedMultiplier = 1.0f
	The amount of red to remove in the next swap (done as 255 - (255 * Multiplier * 0.0039f).
float	BlueMultiplier = 1.0f
	The amount of blue to remove in the next swap (done as 255 - (255 * Multiplier * 0.0039f).
float	GreenMultiplier = 1.0f
	The amount of green to remove in the next swap (done as 255 - (255 * Multiplier * 0.0039f).
float	AlphaMultiplier = 0.8f
	The amount of alpha to remove in the next swap (done as 255 - (255 * Multiplier * 0.0039f).
Public Attributes inherited from VRenderGroup
std::unique_ptr< VSprite >	Sprite = nullptr
	The sprite that the group will render to. Refer to this if you want to transform the render output.
sf::Color	BackgroundTint = sf::Color::Transparent
	The background colour the sprite will have.
std::unique_ptr< VPostEffectBase >	PostEffect = nullptr
	Post Process (Shader) Effect to apply to the sprite.
std::unique_ptr< VCamera >	Camera = nullptr
	Camera for the sprite's render view.
bool	RenderViewTransform = true
	If true, the camera's render view will be transformed based on the sprite's current transform, else it will use the camera's render view.
VRenderGroupOutside	RenderOutside = VRENDERGROUP_NO
	If true, the content data would also be rendered outside of the sprite area. Used if you want an effect to apply to a specific area.
Public Attributes inherited from VBase
bool	active = true
	Base can be updated using Update if true.
bool	visible = true
	Base can be rendered using Draw if true.
bool	alive = true
	Helper member that is mainly used filter out behaviours to objects which aren't alive in the scene.
bool	exists = true
	Base can be updated and rendered if true, else it would no longer be treated as being part of the scene.
VType	type = NONE
	Base object type, typically set in the constructor of an inherited object to specify what type it is.
uint32_t	RefCount = 0
	Counts the amount of times the object is referenced in groups, ensures an object is only destroyed when no longer part of a single group.

Detailed Description

Special VRenderGroup that applies a trail to objects it contains within the area.

Constructor & Destructor Documentation

VTrailArea() [1/2]

VTrailArea::VTrailArea	(	float	x,
		float	y,
		unsigned int	width,
		unsigned int	height,
		unsigned int	maxSize = 0
	)

Parameters

x	X position of the sprite.
y	Y position of the sprite.
width	Width of the sprite (also sets the width of the render area).
height	Height of the sprite (also sets the height of the render area).
maxSize	The fixed length of the group. If 0, then the VGroup has no limit in size.

VTrailArea() [2/2]

VTrailArea::VTrailArea	(	sf::Vector2f	position,
		sf::Vector2u	size,
		unsigned int	maxSize = 0
	)

Parameters

position	Position of the sprite.
size	Size of the sprite (also sets the size of the render area).
maxSize	The fixed length of the group. If 0, then the VGroup has no limit in size.

Member Function Documentation

Draw()

virtual void VTrailArea::Draw ( sf::RenderTarget &  RenderTarget )

overridevirtual

Applies the renderTex to the sprite and renders the sprite to the scene.

Parameters

RenderTarget

The game's sf::RenderTarget object to render data onto.

Reimplemented from VRenderGroup.
