After upgrade to 0.1.0 packages,burst throw exception in first frame after loading scene where I build nodes graph and rebuild invalid nodes in locations with obstaces.
In Bursted IJob on trying call Remove for NativeMultiHashMap:
bool initialNodeHasConnection =
graph.TryGetFirstValue(node, out var connectedNode, out var connectedIt);
while (initialNodeHasConnection)
{
if (connectedNode.Location != node.Location)
{
...
}
else
{
graph.Remove(connectedNode, node); // <---- Here
}
initialNodeHasConnection = graph.TryGetNextValue(out connectedNode, ref connectedIt);
}
Where graph is NativeMultiHashMap<PortalNode, PortalNode>.
Error:
E:\GAMEDEV\REPOSITORY\Elinor\Packages\com.unity.collections@0.1.0-preview\Unity.Collections\NativeHashMap.cs(1013,13): error: Accessing the type `MM.CrowdPathFinding.PortalNode` is not supported by burst

It happens only once. Before 0.1.0 all works without any problems.
In Burst Inspector it happens too:
It drops on if (typeof(TValueEQ) != typeof(TValue)) on 1013 row of NativeMultiHashMap in NativeHashMap.cs in Collections package, previously I used TryRemove here but after upgrate it’s not exists (cause WorldDiff removed).
Type:
public struct PortalNode : IEquatable<PortalNode>, IEquatable<int2>
{
public int2 Coords;
public int Cost;
public int Location;
public int Width;
public LocationSide Side;
public static bool operator ==(PortalNode n1, PortalNode n2)
{
return math.all(n1.Coords == n2.Coords);
}
public static bool operator !=(PortalNode n1, PortalNode n2)
{
return !math.all(n1.Coords == n2.Coords);
}
public bool Equals(PortalNode other)
{
return Coords.Equals(other.Coords);
}
public bool Equals(int2 other)
{
return Coords.Equals(other);
}
public override int GetHashCode()
{
return Coords.GetHashCode();
}
}
Anyway it’s easy to implement
