There is something bug, I recommend you find the problem, fix it, or not use it.

UpdateSystem

UpdateSystem is a lightweight and flexible update system for managing game loops or real-time simulations.

It leverages the custom ZeroTimer library for precise timekeeping, making it suitable for high-performance applications.

Features

• Manage callbacks for frame updates
• Adjustable target frames per second (FPS)
• Uses a zero dependency custom timer

Usage

To use the UpdateSystem, include the header files in your project.

Below is an example of how to integrate and use the UpdateSystem:

#include <UpdateSystem.h>

void UpdateCallback(float deltaTime, float fps)
{
    std::cout << "DeltaTime: " << deltaTime << ", FPS: " << fps << std::endl;
}

int main()
{
    UpdateSystem updateSystem(60.0f); // Target 60 FPS

    updateSystem.RegisterCallback(UpdateCallback, "UpdateCallback");

    updateSystem.RegisterCallback([&](float deltaTime, float fps) {
        if (capture.Capture())
            sender.SendData(capture.GetImageData(), capture.GetWidth(), capture.GetHeight());
    }, "monitor_capture");

    updateSystem.run();

    updateSystem.UnregisterCallback(UpdateCallback);

    updateSystem.UnregisterCallback(monitor_capture);

    updateSystem.Stop();

    return 0;
}

API Reference

UpdateSystem(float targetFps)

Constructor to initialize the update system with a target FPS.

void RegisterCallback(std::function<void(float, float)> callback, std::string name)

Registers a callback function to be called during the update loop.

void UnregisterCallback(std::string name)

Unregisters a previously registered callback.

void Run()

Starts the update loop. This function blocks and runs until stop() is called.

void Stop()

Stops the update loop.

float GetFPS() const

Returns the current FPS.

void FixedUpdate(float deltaTime)

Called internally to perform fixed updates.
