I have disallowed building, but players are able to place ladders.

The ladders are placing straight up and down no matter how they look before you place them.

Allow Players To Use Ladders

building does not apply to ladders. use that instead

it is intended that they are straight up and down since I cannot figure out how to get the rotation

Yeah I have the same settings. Ladders use to place normally is all. Just noticed this either since 2.0 or the last patch.

ah I see, I'll check out their placement.

are you also saying that option does not prevent players from placing ladders when its set to false?

Players are still able to place ladders.
Let's say a player is attempting to place a ladder at an angle because a base design somehow forces them to. When the ladder is actually placed, the ladder is straight up and down instead of at the angle the player attempted to place it at. I had a player report this to me a day or two ago, and I have confirmed this is what is happening.
This is for the premium version, but I'm not sure that is a cause for the problem.

I am not able to place ladders when

Allow Players To Use Ladders​

is set false in the config file

post your config

Ah. Sorry for the confusion!

"Allow Players To Build": false,
"Allow Players To Use Ladders": true,

These are my settings. They should be able to place ladders. They just aren't placing correctly. They use to place correctly.

return input.TryPlaceLadder(target.player, raid);

remove return from this line and it's placing fine for me now. just know it will always place straight up and down in areas rust does not allow you to build. i do not know how to get the rotation and no one else that i've asked does either
