unet-controller's Introduction
An authoritative CharacterController based controller for use in Unity's UNet.
Features
Client-side prediction.
Client-side reconciliation.
Interpolation.
Snapping to grid in order to suppress floating point nature.
Relatively low overhead.
Quake-like strafing. But most likely very incomparable.
Crouching.
Animations.
Network data analyzer to compare the results between the server and the client.
First person and third person camera.
Sliding of steep surfaces.
Ability to set AI target (basic, moves straight towards the target).
Recording and playing back gameplay.
Foot IK.
Ragdoll.
Lag compensation (WIP).
Performance (On 2015 MacBook Pro with quad-core i7)
Up to 1 millisecond on server every time a network update happens.
Up to 1 millisecond on client every time a network update happens. Sometimes it jumps a bit higher if there are a lot of inputs to replay during reconciliation. That is due to high latency.
Very small overhead on non local clients moving.
GC allocations 80 bytes per player. This is due to CharacterController.
Way higher GC allocations on the server side (and while recording gameplay for that matter), due to the need of storing history of the objects for lag compensation.
How does it run fast
It moves character only when network update occurs and then interpolate until the next network update in LateUpdate.
Efficient data reusing with as least locals as possible (as they cause GC allocations).
Current issues
Update Once and Lerp mode does not work well with the update rates over 50hz. Use lower send rate or a higher one with Update Once mode.
TODO
Add jumping between updates so jumping would feel good even on small update periods.
