Detailed Description

Represents a 2D transformation for an object (translation, rotation, and scaling).

The Transform2D class allows you to apply various 2D transformations to an object, including movement (via translation), rotation, and scaling. The transformations are stored in the class's member variables and can be applied to render the object with the desired transformations.

Constructor & Destructor Documentation

Transform2D()

Raftel::Transform2D::Transform2D

(

)

Default constructor for Transform2D.

Initializes the transformation with default values:

• position: (0,0)
• scale: (1.0, 1.0)
• angle: 0.0f
• velocity: (0.0f, 0.0f)

~Transform2D()

Raftel::Transform2D::~Transform2D

(

)

Destructor for Transform2D.

Cleans up any resources used by the transformation (though none are dynamically allocated here).

Member Function Documentation

ApplyTransform()

void Raftel::Transform2D::ApplyTransform

(

)

Applies the accumulated transformations (translation, rotation, scaling).

This method applies the current transformation (position, scale, and rotation) to the object. The transformation is applied by modifying the OpenGL matrix stack.

EndTransform()

void Raftel::Transform2D::EndTransform

(

)

Ends the current transformation and restores the previous matrix state.

This method pops the current transformation from the OpenGL matrix stack, restoring the previous transformation state.

Rotate()

void Raftel::Transform2D::Rotate

(

float

angle

)

Rotates the object by the specified angle.

This method updates the object's rotation angle.

Parameters

angle

The angle (in degrees) to rotate the object by.

Scale()

void Raftel::Transform2D::Scale	(	Vec2	scale,
		float	deltaTime )

Scales the object by the given factor.

This method updates the scale of the object by a scaling factor.

Parameters

scale	The scaling factor to apply to the object.
deltaTime	The time elapsed, used to scale the transformation.

Translate()

void Raftel::Transform2D::Translate

(

float

deltaTime

)

Translates the object by applying its velocity over time.

This method updates the object's position based on its velocity, scaled by the deltaTime.

Parameters

deltaTime

The time elapsed, used to scale the velocity.
