Detailed Description

ECS component that defines the scaling factor for an entity in 2D space.

The scale determines how much the entity is scaled along the X and Y axes. It is typically used to transform logical coordinates into pixel coordinates.

Constructor & Destructor Documentation

ScaleComponent()

wEngine::ScaleComponent::ScaleComponent

(

sf::Vector2f

scale = { 1.0f, 1.0f }

)

Constructs a ScaleComponent with the given scale.

Parameters

scale

Initial scale vector (must be strictly positive, defaults is ( 1.0f, 1.0f ).

Exceptions

std::invalid_argument

if any scale component is non-positive.

Returns

The scale as an sf::Vector2f (X and Y scale).

setScale()

void wEngine::ScaleComponent::setScale

(

sf::Vector2f

newScale

)

Sets a new scale factor.

Parameters

newScale
