Question Entities Graphics 1.0.0-pre.65 The TransformAspect is gone. How do I replace it

I am new to DOTS and find that TransformAspect no longer exists.

Problems to be solved:

When moving an object, I wrote how to change the position of the object in the foreach statement of MovingSystem. I hope you can provide an example code for changing the position, thank you!

public partial class MovingSystemBase : SystemBase

{

    protected override void OnUpdate()

    {

        foreach (TransformAspect transformAspect in SystemAPI.Query<TransformAspect>())

        {

            //TODO How to write the code here

            //transformAspect.Position += new float3(SystemAPI.Time.DeltaTime, 0, 0);

        } 

    }

}

 

public partial class MovingSystemBase : SystemBase

{

    protected override void OnUpdate()

    {

          //TODO How to write the code here

         //foreach (TransformAspect transformAspect in SystemAPI.Query<TransformAspect>())

         //{

            //transformAspect.Position += new float3(SystemAPI.Time.DeltaTime, 0, 0);

         //} 

    }

}

 

For the most part, just use LocalTransform

 

Just now, my version is back to Entities Graphics 1.0.0-pre-44 and then upgraded to Entities Graphics 1.0.0-pre-65. I suddenly found that it is OK again. Thank you for your answer

 

I tried to do that like this:

Code (CSharp):

1. foreach (LocalTransform localTransform in SystemAPI.Query<LocalTransform>())
2.             {
3.                 localTransform.Position += SystemAPI.Time.DeltaTime * new float3(1, 0, 0);
4.             }

but I get the error that I cannot modify the members of localTransform as it is a foreach iteration variable.

 

Use

RefRW<LocalTransform>

instead of a value copy.

I.e.:

foreach (var localTransform in SystemAPI.Query<RefRW<LocalTransform>>())

Then modify the position via:

localTransform.ValueRW.Position += SystemAPI.Time.DeltaTime * new float3(1, 0, 0);

 

Thanks, I knew that I had to get a ref in there somehow, but didn't now how

 

Problem here being the main reason the TransformAspect was useful though, that of manipulating the transform of entities in a hierarchy. Correct me if I'm wrong, but adjusting the LocalTransform on a child can cause things to get out of sync with the more complicated hierarchy which is what TransformAspect handled for us. Unless LocalTransform now also handles that?
