UIObject::UIObject	(	float	x,
		float	y,
		float	width,
		float	height
	)

Constructs the UIObject.

Parameters

x	The x position (Top left of the object).
y	The y position (Top left of the object).
width	The width (Between 0 and 200).
height	The height (Between 0 and 200).

Parameters

x	The x position (Top left of the object).
y	The y position (Top left of the object).
width	The width (Between 0 and 200).
height	The height (Between 0 and 200).
surface	A pointer to the surface for the texture.

Member Function Documentation

glm::vec2 UIObject::convertToOpenGLCoordinate ( glm::vec2  coordinates )

private

Converts the coordinates to work with OpenGL. It takes the coordinates and converts them to a number between 0 and 2. It then takes this and -1 from each, setting it to the bottom left position. It then flips the coordinate along the y axis to get the top left position.

Parameters

coordinates

The coordinates to convert.

Returns

The converted coordinates.

Here is the caller graph for this function:

void UIObject::draw

(

Shader *

shader

)

A function to draw to the screen.

Parameters

shader

A pointer to the Shader to use.

Here is the caller graph for this function:

void UIObject::initialiseObject ( SDL_Surface *  surface )

private

Initialise the UIobject.

Parameters

surface

A pointer to the surface for the texture.

void UIObject::initialiseTexture ( SDL_Surface *  surfac )

private

Initialise the texture.

Parameters

surface

A pointer to the surface for the texture.
