❓ What is it?

Simple yet effective input buffering with just 4 lines of code! ⚡ Never miss player actions again - perfect for jumps, dashes, and combo moves.

Check if buffer isn't expired at any given moment, configure buffer's lifetime, cache input values & etc.

💡 Why Use Input Buffering?

Eliminate frustrating gameplay moments!

When players press jump just before landing, your logic might ignore it. This solution: Buffers inputs so they execute when conditions are right!

// Problem solved in 3 simple steps:
jumpBuffer.Set();          // 1. Buffer on player input
if (jumpBuffer.HasBuffer)  // 2. Check when it's needed
    PerformJump();         // 3. Execute perfectly!

💾 Installation

• Open Unity Package Manager (Window > Package Manager) OR (Window > Package Management > Package Manager) in Unity 6;
• Click "+" → "Add package from git URL";
• Paste this repo's URL;
• Hit Install;

🚀 Getting started

Step 1: Define buffers

First of all declare input buffer:

using MadeYellow.InputBuffer;

public SimpleInputBuffer jumpInputBuffer = new SimpleInputBuffer(); // Init input buffer

You can choose between various types of InputBuffer:

• SimpleInputBuffer - best for buffering button presses (in terms of Unity's InputSystem);
• IntInputBuffer, FloatInputBuffer - best for buffering axis 1D input (in terms of Unity's InputSystem);
• Vector2InputBuffer - best for buffering gamepad stick input or any other 2D input;

Step 2: Buffer input

You may configure buffer hold time from Unity Editor by changing holdTime slider OR by passing holdTime argument to InputBuffer constructor.

After you've set up suitable InputBuffer you should use .Set(); or .Set(value); method each time you want to buffer your input. You may do it like so:

jumpInputBuffer.Set(); // Set input buffer when input happened

Step 3: Check against the buffer

When you need to check if certain input is buffered or not you can perform a simple & performant check:

if (jumpInputBuffer.hasBuffer)
{
  jumpInputBuffer.Reset(); // Reset buffer since we most likely want to perform action required by input only once

  // Your code goes here, e.g. perform Jump action if input was buffered, etc.
}

TIP: It's best to perform those checks each frame in Update() or LateUpdate() method inside your MonoBehaviour, so you won't miss any input. It's super cheap in terms of performance.

Getting the buffered value

If you created InputBuffer of any type except of SimpleInputBuffer (that one doesn't store any value at all, only the fact of the input) you can call .value to retrieve current value of input.

var vectorBuffer = new Vector2InputBuffer();

vectorBuffer.Set(Vector2.one);

Debug.Log(vectorBuffer.value); // Will log (1.00, 1.00)

✅ Recomendations

• Don't reuse single InputBuffer instance for various input actions: one instance for jumping, another for dashing, etc;
• Use .hasBuffer check each frame in order not to miss a frame where you might execute your buffered action;

⚡ Why You’ll Love It

• 🧠 Easy to use – pick a right buffer and use it right away;
• 🚀 Great performance – buffers are greatly optimized under the hood;
• 💎 Clean syntax – .Set() and .Reset() for buffering, .hasBuffer for conditions;
• 📦 Tiny & dependency-free – Minimal footprint;
