Alternative to boolean in IComponentData - Blittable Datatypes

Hi there,

what type would you use instead of boolean in an IComponenData component.

Because of the fact that bool isn't a blittable type, you have to use a different datatype for this.

One aspect would be to use byte because of its size.
Anyway the handling isn't that beautiful...

Maybe a struct that capsules a byte and some methods for conversion to bool will help

Any sugesstion on that?
What do you think?

 

Unity.Mathematics.bool1 should work

 

jeez, bool1 was removed from the latest Mathematics, so currently i don't see any workarounds shipped with library. Looking back into old C days when everyone was making its own bool types everywhere

 

To use `bool1` with `IComponentData` you have to stay with "preview.2".

- "preview.4" removed `bool1` to be in line with float float2 float3.... but without making `bool` blittable.
- "preview.3" crashes everything saying something about reflection even in a scene without any systems. The world bootstrap does not work.

ty for the link. Ok will wait for the blittable bool support, currently im living with simple byte-size wrapper like

Code (CSharp):

1.     public struct TBool
2.     {
3.         private readonly byte _value;
4.         public TBool(bool value) { _value = (byte)(value ? 1 : 0); }
5.         public static implicit operator TBool(bool value) { return new TBool(value); }
6.         public static implicit operator bool(TBool value) { return value._value != 0; }
7. }

 

Great job and thank you!

I've wrote an inspector for this one

Code (CSharp):

1. #if UNITY_EDITOR
2. [CustomPropertyDrawer(typeof(TBool))]
3. class TBoolDrawer : PropertyDrawer
4. {
5.     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
6.     {
7.         var field = property.FindPropertyRelative("_value");
8.         field.intValue = EditorGUI.Toggle(position, label, field.intValue != 0) ? 1 : 0;
9.     }
10. }
11. #endif
