    I'm trying to define an ArcheType, but even the simplest ArcheType gives me the same error.

    I reduced the code to this:
    (Only trying to add 1 component to this ArcheType)

    Code (JavaScript):
    1. let dotArcheType = this.world.createArchetype([game.Tag_TrailDot]);
    The console always throws the following error:
    > Entity archetype has a duplicate (or unsorted) component type -- are you attempting to add a component that already exists?
    > uncaught exception: abort("Assertion failed: types[i - 1] < types, at: C:/Users/Abdul/Documents/tiny/Runtime/modules/core/src/arch/ArchetypeManager.cpp,49,"). Build with -s ASSERTIONS=1 for more info.

    (As you can see I'm only adding one component)

    Any Ideas?

    Using the following code I can get a working archetype. It seems the issue is that you can't add only one component. This makes sense as archetypes are meant to be used for spawning entities that have the same set of components.


    Code (JavaScript):
    1. if (ut.Core2D.Input.getKeyDown(ut.Core2D.KeyCode.S))
    2. {
    3.       let testArcheType = this.world.createArchetype(Tag_This, Tag_IsAn, Tag_Example);
    4.       //returns a pointer to the archetype created.
    5.       console.log(testArcheType);
    6. }

    I assume your problem is invalid way of passing arguments. You should pass the varargs instead of array.

    So, to create an archetype, instead of:

    Code (JavaScript):
    1. let dotArcheType = this.world.createArchetype([game.Tag_TrailDot]);
    you should use:

    Code (JavaScript):
    1. let dotArcheType = this.world.createArchetype(game.Tag_TrailDot);
    I have tried to create an archetype with single component, and it was created successful.
