Detailed Description

ECS component storing the position of an entity in 2D space and supports movement tracking.

This component holds a 2D vector representing the current and previous spatial position of its parent entity.

Usage Examples:

• Default position at origin:

  addComponent< wEngine::PositionComponent >( );

• Custom position:

  addComponent< wEngine::PositionComponent >( sf::Vector2f( 100.0f, 200.0f ) );
