📘 Usage Documentation

1. Create Your Custom Overlay Class

using OverlaySharp;
using ImGuiNET;
using System.Drawing;
using System.Numerics;

public class MyESP : Overlay
{
    public MyESP() : base(new OverlayConfig()) {}

    protected override void Render()
    {
        OverlayDraw.DrawText("top center", "OverlaySharp by BRUUUH", Color.LimeGreen);
        OverlayDraw.DrawBox(new Vector2(100, 200), 150, 80, Color.Red);
        OverlayDraw.DrawLine("bottom left", "top right", Color.Yellow, 1.5f);
        OverlayDraw.DrawCircle("center", 60, Color.Aqua);
    }
}

---

2. Attach to a Process & Run

using System.Diagnostics;
using System.Windows.Forms;

var proc = Process.GetProcessesByName("HD-Player").FirstOrDefault();
if (proc == null) return;

var overlay = new MyESP();
overlay.AttachTo(proc.MainWindowHandle);
Application.Run(overlay);

Replace "HD-Player" with the name of your target process (game, emulator, etc.)

3. Anchor Keywords (Built-in Positioning)

OverlaySharp supports anchor keywords to easily position elements without using raw coordinates.

Examples:

• "top left", "top center", "top right"
• "middle left", "center" / "middle center", "middle right"
• "bottom left", "bottom center", "bottom right"

Or use raw:

new Vector2(300, 500)

4. Drawing API Summary

Method	Description
OverlayDraw.DrawText(pos, string, Color)	Draws text
OverlayDraw.DrawBox(pos, width, height, Color)	Draws rectangle
OverlayDraw.DrawLine(start, end, Color)	Draws a line
OverlayDraw.DrawCircle(center, radius, Color)	Draws circle

Position can be either:

• Vector2
• or anchor string like "bottom right"
