METHODS of the class
The methods of this class render the specified graphical elements to the established target, which by default is the main viewport. It is possible to specify another target (another viewport or a texture) using the SelectViewport() method of the NGN_Graphics class or the RenderToTexture() and RenderToScreen() methods of this class.
Method
void Texture(
NGN_Texture* texture, // Texture
float position_x = DEFAULT_VALUE, // X Position
float position_y = DEFAULT_VALUE // Y Position
);Description
Draws a texture with the NGN_Texture format to the specified target and at the position stored in the texture's properties. Optionally, you can specify the position for this rendering.
Example
ngn->render->Texture(bg);
ngn->render->Texture(bg, 100, 200);Method
void Sprite(
NGN_Sprite* sprite, // Sprite
float position_x = DEFAULT_VALUE, // X Position
float position_y = DEFAULT_VALUE // Y Position
);Description
Draws a sprite with the NGN_Sprite format to the specified target and at the position stored in the sprite's properties. Optionally, you can specify the position for this rendering.
Example
ngn->render->Sprite(ball);
ngn->render->Sprite(ball, 127, 96);Method
void TiledBg(NGN_TiledBg* bg);Description
Draws a background composed of tiles with the NGN_TiledBg format to the specified target.
Example
ngn->render->TiledBg(clouds);Method
void TextLayer(
NGN_TextLayer* layer, // Text Layer
float position_x = DEFAULT_VALUE, // X Position
float position_y = DEFAULT_VALUE // Y Position
);Description
Draws a text layer with the NGN_TextLayer format to the specified target and at the position stored in the layer's properties. Optionally, you can specify the position for this rendering.
Example
ngn->render->TextLayer(textbox);
ngn->render->TextLayer(textbox, 200, 100);Method
void Canvas(
NGN_Canvas* canvas, // Canvas
float position_x = DEFAULT_VALUE, // X Position
float position_y = DEFAULT_VALUE // Y Position
);Description
Draws a canvas with the NGN_Canvas format to the specified target and at the position stored in the canvas's properties. Optionally, you can specify the position for this rendering.
Example
ngn->render->Canvas(mydraw);
ngn->render->Canvas(mydraw, 10, 10);Method
void Video(
NGN_VideoStream* video_frame, // Video stream object
float position_x = (float)NGN_DEFAULT_VALUE, // X position (optional)
float position_y = (float)NGN_DEFAULT_VALUE // Y position (optional)
);Description
Renders the current frame of a video stream to the backbuffer. If X and Y coordinates are not specified, the ones stored in the video object are used. The method automatically applies all properties configured in the stream, including scaling, rotation, pivot point, flipping, alpha transparency, and color tinting.
Example
ngn->render->Video(intro);
ngn->render->Video(intro, 0.0f, 0.0f);Method
void Viewports();Description
Renders the content of all enabled viewports.
Example
ngn->render->Viewports();Method
void RenderToTexture(NGN_Texture* texture);Description
Selects and sets a texture as the render target.
Example
ngn->render->RenderToTexture(surface);Method
void RenderToScreen();Description
Sets the screen (or VIEWPORT) as the render target.
Example
ngn->render->RenderToScreen();
