## Detailed Description

Define the states used for drawing to a RenderTarget

There are six global states that can be applied to the drawn objects:

- the blend mode: how pixels of the object are blended with the background
- the stencil mode: how pixels of the object interact with the stencil buffer
- the transform: how the object is positioned/rotated/scaled
- the texture coordinate type: how texture coordinates are interpreted
- the texture: what image is mapped to the object
- the shader: what custom effect is applied to the object

High-level objects such as sprites or text force some of these states when they are drawn. For example, a sprite will set its own texture, so that you don't have to care about it when drawing the sprite.

The transform is a special case: sprites, texts and shapes (and it's a good idea to do it with your own drawable classes too) combine their transform with the one that is passed in the RenderStates structure. So that you can use a "global" transform on top of each object's transform.

Most objects, especially high-level drawables, can be drawn directly without defining render states explicitly – the default set of states is ok in most cases.

window.draw(sprite);

If you want to use a single specific render state, for example a shader, you can pass it directly to the Draw function: sf::RenderStates has an implicit one-argument constructor for each state.

window.draw(sprite, shader);
sf::RenderStates::shader
const Shader * shader
Shader.
Definition RenderStates.hpp:136

When you're inside the Draw function of a drawable object (inherited from sf::Drawable), you can either pass the render states unmodified, or change some of them. For example, a transformable object will combine the current transform with its own transform. A sprite will set its texture. Etc.

## Constructor & Destructor Documentation

## ◆ RenderStates() [1/7]

sf::RenderStates::RenderStates | ( |  | ) |
| default

Default constructor.

Constructing a default set of render states is equivalent to using sf::RenderStates::Default. The default set defines:

- the BlendAlpha blend mode
- the default StencilMode (no stencil)
- the identity transform
- a nullptr texture
- a nullptr shader

## ◆ RenderStates() [2/7]

sf::RenderStates::RenderStates | ( | const BlendMode & | theBlendMode | ) |

Construct a default set of render states with a custom blend mode.

Parameters

  theBlendMode | Blend mode to use

## ◆ RenderStates() [3/7]

sf::RenderStates::RenderStates | ( | const StencilMode & | theStencilMode | ) |

Construct a default set of render states with a custom stencil mode.

Parameters

  theStencilMode | Stencil mode to use

## ◆ RenderStates() [4/7]

sf::RenderStates::RenderStates | ( | const Transform & | theTransform | ) |

Construct a default set of render states with a custom transform.

Parameters

  theTransform | Transform to use

## ◆ RenderStates() [5/7]

sf::RenderStates::RenderStates | ( | const Texture * | theTexture | ) |

Construct a default set of render states with a custom texture.

Parameters

  theTexture | Texture to use

## ◆ RenderStates() [6/7]

sf::RenderStates::RenderStates | ( | const Shader * | theShader | ) |

Construct a default set of render states with a custom shader.

Parameters

  theShader | Shader to use

## ◆ RenderStates() [7/7]

sf::RenderStates::RenderStates | ( | const BlendMode & | theBlendMode,
|  | const StencilMode & | theStencilMode,
|  | const Transform & | theTransform,
|  | CoordinateType | theCoordinateType,
|  | const Texture * | theTexture,
|  | const Shader * | theShader )

Construct a set of render states with all its attributes.

Parameters

  theBlendMode | Blend mode to use
  theStencilMode | Stencil mode to use
  theTransform | Transform to use
  theCoordinateType | Texture coordinate type to use
  theTexture | Texture to use
  theShader | Shader to use
