Arete Engine

What is Arete?

Arete Engine is a new type of unified-memory game engine. Arete is an ECS, Rust-based game engine with a focus on performance, optimization, and ergonomics. It intends to be a complete engine solution, from coding to rendering. It is particularly fast on unified-memory platforms -- that is, phones, VR headsets, many laptops, and consoles.

Arete is in early development 🚧

Arete is an early stage engine. Currently, our engine consists primarily of a working unified-memory runtime. It is missing many features, and the features it does have will change. Please see our public roadmap below.

Getting Started

• Getting Started: We provide getting started documentation for Rust and C++.

Demos

We provide a separate repo for playable demos and demo code.

• Playable Demos: Precompiled, ready-to-run examples.
• Demo Code: Code for our examples.

arete-engine's Issues

-[MTLTextureDescriptorInternal validateWithDevice:]:1357: failed assertion

When attempting to run the example rust project on macOS, I get the following errors:

-[MTLTextureDescriptorInternal validateWithDevice:]:1357: failed assertion `Texture Descriptor Validation
MTLTextureDescriptor: MTLResourceStorageModeMemoryless is not a supported storage mode on this device.
MTLTextureDescriptor: Depth, Stencil, DepthStencil textures cannot be allocated with MTLResourceStorageModeMemoryless on this device.
'

Steps to reproduce

1. Download the macOS prerelease build
2. Run ./run-macos.sh in either game-rust or game-cpp
3. Witness Arete crash

System specs

Wow, a good start. When can we get the Arete Engine? Will there be an editor for the arete engine?

red lines when rendering (macOS)

When entering fullscreen on macOS, red lines start appearing in the background.

Reproduction steps:

1. Compile game on Intel macOS
2. Put game in full screen
3. Watch the red lines
