Detailed Description

2D drawable component for rendering rectangular primitives.

Represents a simple 2D quad used for sprites, UI widgets, text, or procedural materials. Provides a lightweight implementation of a 2D drawable with transform and material properties inherited from Drawable2D.

Note

Not copyable or assignable.

{
    mMaterialName = materialName;
}

SetMeshName()

void rendering_engine::DrawableComponent::SetMeshName

{
    mMeshName = meshName;
}

Update()

void rendering_engine::Quad2D::Update ( float deltaTime )

overridevirtual

Updates logic (animation, movement, etc.) for this drawable.

Parameters

deltaTime

Time step (seconds).
