How does the BuoyancySensor exactly work? Whenever the object is touching the water it fires TouchingSurface = false, however whenever the object is touching the surface it also fires TouchingSurface = false, and sometimes it even gets reversed and on both of these fires = true, I simply do not understand how this thing exactly works. The roblox Documentation isn’t much help.
print(bobber.BuoyancySensor.TouchingSurface)
local touchsurface = bobber.BuoyancySensor.TouchingSurface
if touchsurface == false then
print("player is fish")
elseif touchsurface == true then
print("player is not fish")
end
All that I want to achieve is for it to read properly whenever the object is touching water and whenever not. And yes the UpdateType is set to OnRead
local REGION_START = object.Position
local REGION_END = object.Position
local function printRegion(terrain, region)
local materials, occupancies = terrain:ReadVoxels(region, 1)
local size = materials.Size -- Same as occupancies.Size
for x = 1, size.X, 1 do
for y = 1, size.Y, 1 do
for z = 1, size.Z, 1 do
print(("(%2i, %2i, %2i): %.2f %s"):format(x, y, z, occupancies[x][y][z], materials[x][y][z].Name))
end
end
end
end
local region = Region3.new(REGION_START, REGION_END)
print(printRegion(workspace.Terrain, region))
This property is true when any position on the BasePart is touching Terrain water. The detection measurements are not exact and may use the bounding box of the part instead of its exact geometry.
FullySubmerged
This property is true when the entirety of the BasePart is submerged in Terrain water with at least one voxel of water above it.
This function returns a description of a volume that contains all BasePart children within a Model. The volume’s orientation is based on the orientation of the PrimaryPart, and matches the selection box rendered in Studio when the model is selected. Mirroring the behavior of Terrain:FillBlock(), it returns a CFrame representing the center of that bounding box and a Vector3 representing its size.
If there is no PrimaryPart for the model, the bounding box will be aligned to the world axes.
Returns
A CFrame representing the orientation of the volume followed by a Vector3 representing the size of the volume.
local Workspace = game:GetService("Workspace")
local model = Workspace.Model
local part = Workspace.Part
local orientation, size = model:GetBoundingBox()
-- Resize and position part equal to bounding box of model
part.Size = size
part.CFrame = orientation
Yes, I managed to find a way to make it work. What i did was Instance a new part parented to workspace and then the sensor with the sensor being parented to the part and then checking if the part is touching the water. This ended up working. Thank you!
local Bob = script.Parent
function GetBobBoundingBox() : (CFrame, Vector3)
local transform = Bob.CFrame
local size = Bob.Size
if Bob:IsA("Model") then
transform, size = Bob:GetBoundingBox()
end
return transform, size
end
while task.wait(1) do
local transform, size = GetBobBoundingBox()
-- check if touching water
local min = transform.Position - (0.5 * size)
local max = transform.Position + (0.5 * size)
local bobRegion = Region3.new(min,max):ExpandToGrid(4)
local material = workspace.Terrain:ReadVoxels(bobRegion, 4)[1][1][1]
if material == Enum.Material.Water then
print("In water!")
else
print("Not in water.")
end
end
