Vault Libray for Unity3D

DOWNLOAD: Latest build (Unity package)

Vault.List - Continuous data array with dynamic size similar to C++ std::vector<T> or C# List<T>. It uses an optimized native array implemented on C that is even faster than STL C++ containers (apporix. 10% faster) and has zero C# memory allocations.

Supported platforms:

• Standalone Mono. Windows/MacOS/Linux
• Standalone IL2CPP. Windows/MacOS/Linux
• Mobile. iOS/Android
• Other through IL2CPP or specific shared libraries

Advantages:

• Doesn’t use any Unity3D features. Can work with any C# code
• Continuous data array with dynamic size
• Fast and small prebuild native libraries
• No C# memory allocations and C# GC
• You manage your memory (Free means deleting container and releasing memory)

Usage

Vault.List is a continuous container with dynamic size. Similar to C++ std::vector<T> or C# List<T> or Unity’s NativeList<T>

// New list with default initializer
// Vault.List is a struct. Zero allocations in C# memory
var vecArr = new Vault.List<Vector2>(10, new Vector2(1.0f, 1.0f));
// Set element value
vecArr[9] = new Vector2(101f, 102f);
vecArr[0] = new Vector2(101f, 102f);
// Resize list
vecArr.Resize(14);
// Add element to list.
vecArr.Add(new Vector2(21f, 22f));
// Fast remove element by swap with last element
vecArr.RemoveBySwap(1);
// Relatively slow remove element by memmove
vecArr.Remove(1);
// Swap elements
vecArr.Swap(0, 1);
// Clear list
vecArr.Clear();
// Free list after use
// Completely release unmanaged memory
vecArr.Free();

Performance

Performance (IL2CPP Builds) is similar (±10%) to Unit’s NativeList<T>
