• Post processing

• Serialisation, Deserialisation with Serde

• Resource packing system

Installation

Command line:

cargo add let_engine

Tips

For best performance compile to release with this in the Cargo.toml

[profile.release]

Contribution

feel free to contribute. Go resolve some of the issues I made or take a look at this: also read the contribution guidelines.

Plan

Once all planned features have been implemented, the code looks acceptable, the performance is acceptable and when I am happy with the format I will release 1.0.0.

After the first stage of my game engine is completed, this is where I will start advertising the game engine. Only together this game engine can be made great.
