Layer

[Well-met]

Is there a layer that only renders above the land but NOT into the sea? I have a mechanic that produces sinkholes but they keep overlapping into the sea and it's not pretty

I'm not sure if there is a layer like this, but why don't you make it like the component sinkholespawner?

Spoiler

local SINKHOLD_BLOCKER_TAGS = { "antlion_sinkhole_blocker" }
function SinkholeSpawner:SpawnSinkhole(spawnpt)
    local x = GetRandomWithVariance(spawnpt.x, TUNING.ANTLION_SINKHOLE.RADIUS)
    local z = GetRandomWithVariance(spawnpt.z, TUNING.ANTLION_SINKHOLE.RADIUS)

    local function IsValidSinkholePosition(offset)
        local x1, z1 = x + offset.x, z + offset.z
        if #TheSim:FindEntities(x1, 0, z1, TUNING.ANTLION_SINKHOLE.RADIUS * 1.9, SINKHOLD_BLOCKER_TAGS) > 0 then
            return false
        end
        for dx = -1, 1 do
            for dz = -1, 1 do
                if not TheWorld.Map:IsPassableAtPoint(x1 + dx * TUNING.ANTLION_SINKHOLE.RADIUS, 0, z1 + dz * TUNING.ANTLION_SINKHOLE.RADIUS, false, true) then
                    return false
                end
            end
        end
        return true
    end

    local offset = Vector3(0, 0, 0)
    offset =
        IsValidSinkholePosition(offset) and offset or
        FindValidPositionByFan(math.random() * 2 * PI, TUNING.ANTLION_SINKHOLE.RADIUS * 1.8 + math.random(), 9, IsValidSinkholePosition) or
        FindValidPositionByFan(math.random() * 2 * PI, TUNING.ANTLION_SINKHOLE.RADIUS * 2.9 + math.random(), 17, IsValidSinkholePosition) or
        FindValidPositionByFan(math.random() * 2 * PI, TUNING.ANTLION_SINKHOLE.RADIUS * 3.9 + math.random(), 17, IsValidSinkholePosition) or
        nil

    if offset ~= nil then
        local sinkhole = SpawnPrefab("antlion_sinkhole")
        sinkhole.Transform:SetPosition(x + offset.x, 0, z + offset.z)
        sinkhole:PushEvent("startcollapse")
    end
end

 

This function chooses the exact point where the character is standing or a random point near the character and checks if the point is passable, which also includes a check if there is water at this point. You could change this function to your preferences.

well, yes, but my special sinkhole has a bigger graphic scale so it'll clip into the sea even with this failsafe

If that's the case, replace all instances of TUNING.ANTLION_SINKHOLE.RADIUS with the radius of your sinkhole. The sinkhole of the antlion has a radius of 2.5, the function should find a place without overlapping into the sea if you choose the right radius. You can make it even bigger if you want more space in between the sea and your sinkholes.
