Hey there!
I’m working on a Mars game, where you explore the surface as a rover. The terrain is procedurally generated with the following script (a slightly modified version of the devhub one):
local Players = game:GetService("Players")
------------------------------------------------------------------------------------------------------------------------------------------------
local BASE_HEIGHT = 10 -- The main height factor for the terrain.
local CHUNK_SCALE = 8 -- The grid scale for terrain generation. Should be kept relatively low if used in real-time.
local RENDER_DISTANCE = 500 / 2 -- The length/width of chunks in voxels that should be around the player at all times
local X_SCALE = 300 / 4 -- How much we should strech the X scale of the generation noise
local Z_SCALE = 300 / 4 -- How much we should strech the Z scale of the generation noise
local GENERATION_SEED = math.random() -- Seed for determining the main height map of the terrain.
------------------------------------------------------------------------------------------------------------------------------------------------
local chanceDebounce = false
local chunks = {}
local function chunkExists(chunkX, chunkZ)
if not chunks[chunkX] then
chunks[chunkX] = {}
end
return chunks[chunkX][chunkZ]
end
local function mountLayer(x, heightY, z, material)
local beginY = -BASE_HEIGHT
local endY = heightY
local cframe = CFrame.new(x * 4 + 2, (beginY + endY) * 4 / 2, z * 4 + 2)
local size = Vector3.new(4, (endY - beginY) * 4, 4)
workspace.Terrain:FillBlock(cframe, size, material)
end
function makeChunk(chunkX, chunkZ)
local rootPosition = Vector3.new(chunkX * CHUNK_SCALE, 0, chunkZ * CHUNK_SCALE)
chunks[chunkX][chunkZ] = true -- Acknowledge the chunk's existance.
for x = 0, CHUNK_SCALE - 1 do
for z = 0, CHUNK_SCALE - 1 do
local cx = (chunkX * CHUNK_SCALE) + x
local cz = (chunkZ * CHUNK_SCALE) + z
local noise = math.noise(GENERATION_SEED, cx / X_SCALE, cz / Z_SCALE)
local cy = noise * BASE_HEIGHT + 15
local chance = math.random(1,50)
if chance >= 1 and chance <= 2 then
mountLayer(cx, cy, cz, Enum.Material.Rock)
else
mountLayer(cx, cy, cz, Enum.Material.Limestone)
end
end
end
end
function checkSurroundings(location)
local chunkX, chunkZ = math.floor(location.X / 4 / CHUNK_SCALE), math.floor(location.Z / 4 / CHUNK_SCALE)
local range = math.max(1, RENDER_DISTANCE / CHUNK_SCALE)
for x = -range, range do
for z = -range, range do
local cx, cz = chunkX + x
local cz = chunkZ + z
if not chunkExists(cx, cz) then
makeChunk(cx, cz)
end
end
end
end
while true do
for _, player in pairs(workspace:GetDescendants()) do
if player:IsA("Humanoid") then
local humanoidRootPart = player.Parent:FindFirstChild("HumanoidRootPart")
if humanoidRootPart then
checkSurroundings(humanoidRootPart.Position)
end
end
end
wait(1)
end
The main problem I find myself facing is that I want to also randomly generate rocks, which would be parts, scattered around on the surface of the generated terrain. Being a not very advanced scripter, I don’t have any idea of how to do this, so I seek help from the rest of you!
I appreciate any and all help!
