When trying to create a development build (the normal build works) then the Burst Compiler will throw exceptions because I am calling the generic default interface function - start.DefaultEquals(goal).
I believe this to be a bug, since building the project normally works and there are no errors when saving the script. It only doesn’t work when trying to create a development build.
Unity 2022.3.18f1
Burst 1.8.15
Entities 1.2.0
How to replicate?
- Setup a fresh project with Entities & Burst
- Copy paste the Code
- Try to create a development build
namespace MyNamespace
{
public partial struct TestSystem : ISystem
{
public void OnCreate(ref SystemState state) { }
public void OnDestroy(ref SystemState state) { }
[BurstCompile]
public void OnUpdate(ref SystemState state)
{
var graph = new MyGenericGraph<MyGridCell>();
var cell1 = new MyGridCell(0);
var cell2 = new MyGridCell(1);
graph.DoSomething(cell1, cell2);
}
}
public struct MyGenericGraph<TNode> where TNode : unmanaged, IUniqueID
{
public bool DoSomething(TNode start, TNode goal)
{
return start.DefaultEquals(goal); // <---- This call does not let me build
//return start.UniqueID == goal.UniqueID; // <---- If I uncomment this line and comment the line above it works
}
}
public interface IUniqueID
{
public uint UniqueID { get; }
// Can't build, because of this function
public bool DefaultEquals<T>(T other) where T : unmanaged, IUniqueID
{
return other.UniqueID == UniqueID;
}
}
public struct MyGridCell : IUniqueID
{
private uint ID;
public uint UniqueID => ID;
public MyGridCell(uint id) { ID = id; }
}
}
