🕹️ polygonBlaster

A retro-inspired twin-stick shooter inspired by Geometry Wars.
Built in C++ with SFML, ImGui, and an ECS design pattern for clean, modular game architecture.

✨ Features

• Fast-paced arcade action with a neon grid aesthetic
• Smooth 2D rendering powered by SFML
• ImGui debug tools for real-time tweaks
• Modular ECS design for scalable gameplay systems
• Particle effects & retro visuals

---

🎮 Controls

• WASD – Move
• Mouse left – Shoot in direction
• Mouse right - Special Attack , yet to implement
• P – Pause
• Esc - Exit

(Controls may change as development continues.)

🚀 Building From Source

Prerequisites

• C++20 compatible compiler (GCC, Clang, or MSVC)
• CMake (>=3.16)
• SFML (>=2.6)
• ImGui

Build Instructions

git clone https://github.com/Strangerfuture/polygonBlaster
cd polygonBlaster
mkdir build && cd build
cmake ..
make
./polygonBlaster

Config Specification:

Window W H FL FS

• This line declare that the SFML Window must be constructed with width W and height H, each of which will be integers, FL is frame Limit that the Window should be set to, FS will be an integer which specifies wheater to display the application in full-screen mode (1) or not (0).

• Min / Max Vertices VMIN,VMAX int, int

 vec2f speed = {
    SMIN + rand() % (SMAX - SMIN + 1),
    SMIN + rand() % (SMAX - SMIN + 1),
 } 

float Vertices = VMIN + rand() % (VMAX - VMIN + 1);

vec2f Postion = {
    SR + rand() % ((wWidth - SR) - SR + 1),
    SR + rand() % ((wHeight- SR) - SR + 1),
}
