An example where I need to get tilemap tile. It has a sprite, integer position but not float position.
const query = defineQuery(
[
TilePositionComponent, // Vector2I
SpriteComponent, // Sprite
Not(PositionComponent), // Vector2
],
);
const entities = query(world);
Can be found in Query section of "Getting Started"
So you have the Not
option, but not All
and Any
because that is frankly the default behavior(?).

Thank you. I had missed the Not
in the docs. All
is indeed the default behavior.
Any
does not seem to be implemented, but using TC39 Set Methods it can be done easily.
The following fictious code
defineQuery(
[
TilePositionComponent
Any(SpriteComponent, Color)
],
);
can be implemented as
//set methods polyfill
import "core-js/features/set"
const tileQuery = defineQuery(
[
TilePositionComponent
],
);
const spriteQuery = defineQuery(
[
SpriteComponent,
],
);
const colorQuery = defineQuery(
[
Color
],
);
const entities = new Set(tileQuery(world))
.intersects(
new Set(spriteQuery(world))
.union(new Set(colorQuery(world))
);
