Types

type GraphicsComponent

type GraphicsComponent struct {
	ModelName, Mesh, MeshType, Renderer, TextDescription string
}

GraphicsComponent represents data extracted from a graphics component file.

type Inputs

type Inputs struct {
}

type ModelTransfer

type ModelTransfer struct {
	Id component.GOiD
	Gc GraphicsComponent
}

ModelTransfer is used to send creation information to the renderers over a channel.

type TextGraphicsHandler

type TextGraphicsHandler struct {
	// contains filtered or unexported fields
}

TextGraphicsHandler implements the GraphicsHandler interface, but instead of rendering to a graphics context, TextGraphicsHandler instead outputs textual descriptions of each model.

func MakeTextGraphicsHandler

func MakeTextGraphicsHandler() *TextGraphicsHandler

MakeTextGraphicsHandler returns a pointer to a TextGraphicsHandler.

func (*TextGraphicsHandler) DeleteModel

func (tgh *TextGraphicsHandler) DeleteModel(id component.GOiD)

DeleteModel implements the GraphicsHandler interface and deletes the data used for rendering.

func (*TextGraphicsHandler) DrawString

func (tgh *TextGraphicsHandler) DrawString(x, y float32, text string)

DrawString implements the GraphicsHandler interface and outputs a the string passed in as an arguement. The x, y coordinates are ignored.

func (*TextGraphicsHandler) GetSize

func (tgh *TextGraphicsHandler) GetSize() (int, int)

GetSize implements the GraphicsHandler interface, but returns 0, 0 always because the text window has no size.

func (*TextGraphicsHandler) HandleInputs

func (tgh *TextGraphicsHandler) HandleInputs() Inputs

HandleInputs implements the GraphicsHandler interface and returns the inputs recieved since the last query.

func (*TextGraphicsHandler) LoadModel

func (tgh *TextGraphicsHandler) LoadModel(id component.GOiD, gc GraphicsComponent) error

LoadModel implements the GraphicsHandler interface and adds data used to render the components later.

func (*TextGraphicsHandler) Render

func (tgh *TextGraphicsHandler) Render(ids *common.Vector, sm component.SceneManager)

Render implements the Renderer interface and outputs text based on the GOiD's in the list passed as an argument.

func (*TextGraphicsHandler) RenderDiff

func (tgh *TextGraphicsHandler) RenderDiff(ids *common.Vector, sm component.SceneManager)

RenderDiff outputs text based on the GOiD's in the list passed as an argument. The function will only output a new text description if the model has newly come into the scene.

func (*TextGraphicsHandler) Tick

func (tgh *TextGraphicsHandler) Tick() bool

Tick returns the status of the text window.
