The DrawRect method in the HudPainter class is used to draw a rectangle on the HUD (Heads-Up Display) with specified properties such as color, corner radius, border width, and border color. This method is part of the rendering process in the Sandbox game engine, allowing developers to customize the appearance of UI elements.
To use the DrawRect method, you need to provide the following parameters:
rect: A reference to a Rect structure that defines the position and size of the rectangle.color: A reference to a Color structure that specifies the fill color of the rectangle.cornerRadius: A reference to a Vector4 structure that defines the radius of the corners of the rectangle. Each component of the vector corresponds to a corner of the rectangle.borderWidth: A reference to a Vector4 structure that specifies the width of the border for each side of the rectangle.borderColor: A reference to a Color structure that defines the color of the border.Ensure that the HudPainter instance is properly initialized and that the rendering context is set up before calling this method.
// Example usage of HudPainter.DrawRect // Create a HudPainter instance HudPainter hudPainter = new HudPainter(); // Define the rectangle properties Rect rect = new Rect(10, 10, 100, 50); Color fillColor = new Color(0.5f, 0.5f, 0.5f, 1.0f); // Gray color Vector4 cornerRadius = new Vector4(5, 5, 5, 5); // Rounded corners Vector4 borderWidth = new Vector4(2, 2, 2, 2); // Border width Color borderColor = new Color(1.0f, 0.0f, 0.0f, 1.0f); // Red border // Draw the rectangle hudPainter.DrawRect(ref rect, ref fillColor, ref cornerRadius, ref borderWidth, ref borderColor);
