Support for processing entities in multiple threads, based on classic C# threads implementation. Inspired by a similar extension for [LeoEcs Lite](https://github.com/Leopotam/ecslite-threads).

> [!WARNING]
|
|
> The project is a work in progress, API may change.

# Parallel iteration
|
|
``` csharp
|
|
EcsThreadHandler _handler;
|
|
public void Run(EcsPipeline pipeline)
|
|
{
|
|
// Getting the Aspect and entities for iteration.
|
|
var group = _world.Where(out Aspect a);
|
|
|
|
void Handler(ReadOnlySpan<int> entities)
|
|
{
|
|
foreach (var e in entities)
|
|
{
|
|
// Computations in a separate thread.
|
|
a.poses.Get(e).position += a.velocities.Read(e).value * _time.DeltaTime;
|
|
}
|
|
}
|
|
|
|
// Starts parallel iteration over entities,
|
|
// entities will be split into parts with a minimum size of 1000.
|
|
group.IterateParallel(_handler ??= Handler, 1000);
|
|
}
|
|
```
|
|
> The smaller the minimum size of the group part when dividing, the more threads can be utilized. In some situations, too many threads can negatively impact performance.
|
|
|
|
> Inside the handler, creating/deleting entities, adding/removing components on entities is prohibited. Only modification of data within components is allowed.
