Little extra info, in case it's useful. This also looks like it breaks pathfinding for the affected rooms.

Essentially,

I just respawned and my code didn't work. Found out that queries for terrain at non-wall spots were returning "wall". Eventually did a lookForAtArea on the entire room, and found that the entire room is one big wall. This is a new novice area, so my suspicions are that something somewhere is cached. Another player (fritee) was able to reproduce. This seems localized to this novice area. More details in the conversation below.

Guys, can somebody explain this to me... I am very confused.

Anwinity [12:19 PM]

Basically i'm querying the terrain at that spot, which is clearly a swamp, but it's returning wall in the code

In fact, spot checking numerous swamp/wall/plain in the room, they all return wall...

does not behave this way in sim either

Iranite [12:40 PM]

the code works for me. i find swamp where there is swamp.

@Anwinity Are you on multiple shards?

Anwinity [12:41 PM]

Nope

just shard2

Though I just respawned (same shard)

Also, I removed all of my code and reloaded window, and it's still happening

fritee [12:52 PM]

Try using Game.map.getTerrainAt

Does it get you a different result?

Anwinity [12:55 PM]

still wall

Game.spawns["Spawn1"].room.lookForAt(LOOK_TERRAIN, 38, 18);

wall

Game.getObjectById("59f1a11a82100e1594f37bdc").room.lookForAt(LOOK_TERRAIN, 38, 18);

wall

Game.map.getTerrainAt(38, 18, "W29N59");

wall

extra sanity check:

Game.shard.name + Game.map.getTerrainAt(38, 18, "W29N59");

shard2wall

fritee [1:01 PM]

Does room.lookAt also return walls?

You can also try cleaning cache for screeps

If not, then suspect its a bug

Game.map.getTerrainAt(38, 18, "W29N59");

wall

Hmmm

Same

Anwinity [1:02 PM]

JSON.stringify(Game.rooms.W29N59.lookAt(38, 18));

[{"type":"terrain","terrain":"wall"}]

I think it's only this room...

Game.map.getTerrainAt(29, 30, "W30N59");

plain

fritee [1:05 PM]

It also might be the case that this happened due to newbie zone opening up just a while ago. Maybe some caches weren’t updated?

Sergey [1:05 PM]

What about lookAtArea try to look at small square (3x3) to understand what wrong.

fritee [1:05 PM]

Probably will return all walls

But trying out can help

Yup, seems like it happens with all the rooms in the newbie zone

Anwinity [1:07 PM]

ahh..

How long is that normally cached for you think?

fritee [1:07 PM]

Have literally no idea

Best bet would be to continue developing that particular piece after some time, and if bug persists, report it

Anwinity [1:09 PM]

@Sergey lookForAtArea shows the entire room is one big wall

i really like this room so ima give it a day and hope it clears up :l

thanks for the help

Saruss [1:10 PM]

did any other player test that? Everyone on shard2 could do

Anwinity [1:10 PM]

It seems localized to this novice area

fritee [1:10 PM]

I did

Returns a wall

At least Game.map.getTerrainAt. Doubt behaviour with other functions would be different

Saruss [1:11 PM]

Bad thing. There are other problems with newbiezones (like hard to detect where they end). But this one should be posted in Forum, as it destroys automated building code etc.

fritee [1:12 PM]

True. My guess is that because the bug is localised and only relevant to newbie zones wasn’t reported previously

Anwinity [1:12 PM]

Yeah I'm going to write up a forum post
