Combining Constants works in JS but not in Kotlin

[thigg]

Bein able to combine e.g. FIND constants is a very useful feature:

find(FIND_CONSTRUCTION_SITES | FIND_STRUCTURES,...)

I guess there is no nice solution to preserve typing, but mebe we should still make it available?

[Jomik]

Can you not do it with

find(FIND_CONSTRUCTION_SITES or FIND_STRUCTURES,...)

[thigg]

Ah I didn't try the or, just |. Maybe that should be documented somewhere?

[thigg]

No, I get a: Unresolved reference: or when I try: findInRange(FIND_MY_CONSTRUCTION_SITES or FIND_MY_STRUCTURES, 4 )

[thigg]

Idea from @AWRyder : FIND_MY_CONSTRUCTION_SITES.value or FIND_MY_STRUCTURES.value seems to work. Will test.

[thigg]

It is compiled to

pos.findClosestByPath((FIND_MY_STRUCTURES.value or FIND_CREEPS.value) as FindConstant<RoomObject>)

$receiver.pos.findClosestByPath(Kotlin.isType(tmp$_0 = FIND_MY_STRUCTURES | FIND_CREEPS, Object) ? tmp$_0 : throwCCE());

This returns always null.

Maybe because it is no Object?

[thigg]

While you can combine them in JS, this is no valid behavior after all. I think i dreamed of that function ;)

Wrote me a helper for this:

/*
 * Find with multiple flags
 */
fun RoomPosition.findClosestByPathMulti(
        types: Array<FindConstant<RoomObject>>,
        opts: FindClosestByPathOptions<RoomObject>
): RoomObject? {
    val objects: Array<RoomObject> = types.map { Game.rooms[this.roomName]?.find(it) }.foldRight(arrayOf<RoomObject>(), { l, r -> l!! + r })
    return findClosestByPath(objects, opts)
}

//Call with:
pos.findClosestByPathMulti(arrayOf(FIND_MY_STRUCTURES,FIND_MY_CREEPS)as Array<FindConstant<RoomObject>>,options {...})
