VertexScreen

Description: VertexScreen provides low-level drawing functionality for rendering graphics without using image assets. It is designed for drawing primitive shapes such as lines, rectangles, circles, arcs, and polygons directly to the screen.

All VertexScreen drawing calls should be placed inside a scene’s draw(surface) method, as they are executed every frame.

Features

Draw 2D primitive shapes
No image assets required
Immediate-mode rendering
Ideal for debug visuals and UI primitives

Example: Usage

from VertexEngine import VertexScreen

vs = VertexScreen()

def draw(surface):
    vs.Draw.line(surface, (255, 255, 255), (10, 10), (200, 10), 2)
    vs.Draw.circle(surface, (0, 255, 0), (100, 100), 40, 0)

Parameters

VertexScreen.Draw.[func]() — Any primitive drawing function available in the Draw module, such as line, rect, circle, polygon, and others.

Returns

None. Drawing operations are applied directly to the target surface.

Notes

Best used for shapes, UI elements, and debug overlays
Not intended for image rendering (use AssetManager for images)
Executed once per frame inside the active scene
