Detailed Description

A system that manages Entity sprite sizes, positions, and drawing.

It acts on all elements with a RenderComponent and LocationComponent

Member Function Documentation

process()

void RenderSystem::process ( std::shared_ptr< Entity > &  entity, sf::Time  deltaTime  )

protectedvirtual

Processes the Entity graphical data.

Sprites are moved and scaled to align with the Entity LocationComponent data.

Parameters

entity	The entity being processed
deltaTime	The amount of time that has passed since process() was last called on this entity

Implements IteratingSystem.

render()

void RenderSystem::render

(

sf::RenderTarget &

target

)

const

Draws the prepared sprites to the sf::RenderTarget.

This method assumes that it is part of a larger pipeline and that entities may not be the only thing being rendered. Methods such as sf::RenderWindow.display() need to be called after RenderSystem::render() to ensure everything is displayed correctly.

Parameters

target

The target to draw the entities on.
