im in wood 2 how do i do the take cover thing i need a hint

2

check the up to 4 orthogonally adjacent tiles for one that is fully protected (i.e is itself adjacent to a type 2 tile in the same direction as the enemies).

For those who may be interested, I’ve added the CLI interface to the referee: GitHub - Telokis/cg_SummerChallenge2025-SoakOverflow

Looks like a bug in the protocol description:

The next width * height lines: The following 3 inputs for each tile on the grid

But actually there are height lines with 3×width inputs.

Hi !
On the replay here (don’t mind what my agents are doing plz :grin:), shouldn’t the agent 4 have 75% cover regarding my agent 1 ?
Maybe I’m missing something, but it seems like block (4, 2) should grab cover to the enemy :thinking:

Thanks by advance for your answers !

6

Agent 4 doesn’t have any cover from Agent 1 because they’re on the same side of the block.

Hello ! Hope your challenge is going as you wish :slight_smile:

I’m not sure I understand the movement of the agents:
Let’s say we have this configuration:

Agent #1 in (0,8)
Agent #2 in (0,7)

If we output:

“1; MOVE 0 7”;
“2; MOVE 1 7”;

I would have expected agent #1 to be blocked by agent #2.
However since agent #2 is freeing his place by going somewhere else, it seems to be fine !

Is it safe to assume there is a sort of “mouvement solver” and it’s independant of the output order?

Subsidiary question about path:
If we have an agent at 5;5 moving to 7;5 and there is a hindrance at 6;5.
Does the agent go top or bottom to avoid it? I have not found the rule about the path taken.

8

Aaaaah, you mean sides are only left and right ?
I thought block coer worked on 4 directions 


9

Top and bottom too (like on the second screenshot in the examples section)

I agree that the definition of “opposite direction” could be clearer!

If my understanding is correct:
In the replay: B is (#1) and A is (#4)

B . . . . .
. . . . . . X
. . . . . . A
. . . . . . X

the direction of the shot B → A is ‘Right’, however A has protection for ‘Top’ and ‘Bottom’, thus is taking the full shot.
Looking at screenshot 1, the direction might be based on the diagonals (included): (excuse my poor ascii skills)

\ . . . . / . .
. .\ X / . .
. . .A . . .
. ./ X \. .
./ . . . .\ .

Everything on left and right of A is open

10

Hmm, OK :thinking:
By the way, that schema is misleading 
 I foolishly thought green ticks would extend infinitely on right, but too up and down 
 and that it would be the same for all directions and cases

By the way, the second screenshot seems to not agree the first schema 
 How would you explain the two green shields on the bottom left ??

Actually the wood league 2 is poorly explained. You should shoot one of the 2 enemy agents that has the least “front” cover. “Front” means the tile facing you only, regardless of the upper nor bottom tile of the enemy.

What I understood about the covers is:

  • The covers are not in a cone (diagonals): they extend infinitely in 3 directions.
  • The 2nd example shows how 2 different covers intersect each other. The bottom left high shields come from the 75% cover (bottom cover). The upper right low shields come from the 50% cover (right cover). The middle area (bottom right -ish) where both covers have effect is high shield because of the rule
12

The orange agent is orthogonally adjacent to the top side of the high cover and so is protected from being shot from all positions in rows below that cover except for those cells which are adjacent to the cover (marked orange x).

So, the two green shields in the bottom left are there because that row is below the high cover, and those cells are not adjacent to the cover.

Similarly, the agent is orthogonally adjacent to the left side of the low cover and so is protected from being shot from all positions in columns to the right of that cover, again except for the cells that are adjacent to the cover.

The rules do extend to the edge of the grid.

Hi, can anyone spot (here) why agent 1 does only 6 wetness damage to agent 4 on round 3?

EDIT: found it, it was HUNKER_DOWN

14

in wood 2 the instruction for the attached picture says: The orange agent benefits from a low cover while the purple agent does not benefit from any cover.

download (3)

due to the rule: In the case where multiple covers can be considered, only the highest cover will count.

then i think the description must be changed to high cover instead of low cover (i see the box in tile (2,1) is high cover).

15

The orange agent is not orthoganally adjacent to the high cover, so can’t benefit from it.

Hello world,
I am currently in Bronze League.
During each battle, I get no point.
How can I get any?
→ zone ?
→ enemies?

An error occurred during summer camp battle (in french) :

Attention : votre code n’a pas lu toutes les donnĂ©es disponibles depuis l’entrĂ©e standard avant d’avoir Ă©crit sur la sortie standard. Ceci cause une dĂ©synchronisation qui peut entraĂźner des comportements inattendus.

Hello, I am in wood 2 and I would like to read the previous instruction. Where can I find them ?

19

Nowhere, but you don’t need them to pass in Wood 3 :wink:

Both!

:chart_with_upwards_trend: Points

Vous gagnez des points en prenant le contrĂŽle de cases lorsque vous contrĂŽlez une zone plus grande que votre adversaire.

Toute case qui est plus proche de l’un de vos agents que d’un agent ennemi est considĂ©rĂ©e comme Ă©tant sous votre contrĂŽle. Cependant, si un agent a une humiditĂ© supĂ©rieure ou Ă©gale Ă  50, la distance Ă  cet agent sera doublĂ©e lors de cette comparaison.

À chaque tour, Vous marquez autant de points que le nombre de cases supplĂ©mentaires que vous contrĂŽlez par rapport Ă  votre adversaire.

I have just entered Gold League and I am almost always getting a 524 error whenever I submit my code. My program computations are not high. Maybe other player’s computations are?

Is anyone else getting this error?
