pub struct Renderer { /* private fields */ }

Implementations

impl Renderer

pub fn new(font_data: Vec<u8>) -> Self

pub fn set_background_color(&mut self, r: f32, g: f32, b: f32, a: f32)

pub fn render(&mut self, screen_width: f32, screen_height: f32)

매 프레임마다 호출하여 전체 화면을 다시 그리는 메서드 (배경 지우기, 카메라/투영 매트릭스 설정 등)

pub fn text_renderer(&self) -> &TextRenderer

텍스트 렌더링 객체에 접근 (폰트 그리기 등)

pub fn draw_rect( &mut self, x: f32, y: f32, width: f32, height: f32, color: [f32; 4], )

Draws a filled rectangle at (x, y) with given width, height and color. Assumes that self.screen_width and self.screen_height are updated.

pub fn text_renderer_mut(&mut self) -> &mut TextRenderer

Add a new method for mutable access to the text renderer.

pub fn draw_textured_rect( &self, x: f32, y: f32, width: f32, height: f32, texture_id: u32, opacity: f32, )

pub fn draw_triangle(&mut self, vertices: [(f32, f32); 3], color: [f32; 4])

pub fn draw_circle( &mut self, center_x: f32, center_y: f32, radius: f32, color: [f32; 4], )
