My code is going to be used to get a table of the positions of terrain voxels that enemies can pathfind to. I am making a tower defence game and the path material is limestone.
-
I am making parts at the terrain voxel positions to test if the code is working and the positions are correct
-
No matter what I try the parts are not aligned properly, I have tried 3 different ways to place the part positions but none of them work
Screenshot of whats happening
- Is there an easier way to do this? I feel like scanning through every terrain voxel and checking if there is air above it is a really inefficient way to get the positions that enemies can pathfind to, but I can’t think of another way to do it.
local part = game.Workspace:WaitForChild('Region')
local min = part.Position - part.Size
local max = part.Position + part.Size
local region = Region3.new(min, max)
region = region:ExpandToGrid(4)
local function printRegion(terrain, region)
local materials, occupancies = terrain:ReadVoxels(region, 4)
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
if materials[x][y][z] == Enum.Material.Limestone and materials[x][y+1][z] == Enum.Material.Air then
local newPart = Instance.new("Part") -- Creates a new Part instance
newPart.Size = Vector3.new(4, 4, 4) -- Sets the size of the part to 4x4x4
newPart.Anchored = true
-- Solutions I have tried
-- 1. Calculate the CFrame for the part
-- local voxelCenter = Vector3.new(x - 1, y - 1, z - 1) * 4
-- local partCFrame = terrain.CFrame * CFrame.new(voxelCenter)
-- newPart.CFrame = partCFrame -- Sets the CFrame of the part to align with the voxel newPart.Position = worldPosition -- Sets the position of the part to match the voxel coordinates
--2. Calculate the world position for the part based on voxel coordinates
-- local worldPosition = region.CFrame:PointToWorldSpace(Vector3.new(x - 0.5, y - 0.5, z - 0.5) * 4)
-- Set the position of the part to match the voxel coordinates
-- newPart.Position = worldPosition
--3. Simple solution I tried the other ones are AI generated
-- newPart.Position = Vector3.new(x*4,y*4,z*4)
newPart.Parent = game.Workspace -- Sets the parent of the part to the Workspace
print(("(%2i, %2i, %2i): %.2f %s"):format(x, y, z, occupancies[x][y][z], materials[x][y][z].Name))
end
end
end
end
end
printRegion(workspace.Terrain, region)
Thanks in advance for any help
