So today I saw Sebastian Lague’s new video on geography and stuff, and I got a ton of ideas. One of them was to recreate the clouds I saw in the video, with a few changes to fit my style, and well, I’d say I did a pretty good job.
Image:
FYI, the clouds weren’t animated to I just took a screen shot.
Here is the code
local Cloud = {}
function Cloud.Spawn(position: Vector3, baseSize: Vector3, containerSize: Vector3, minSize: number, maxSize: number, density: number, model: boolean, modelName: string?, parent: Instance)
local cloud = { }
local cloudModel
local base = Instance.new("Part")
local sphereMesh = Instance.new("SpecialMesh")
sphereMesh.MeshType = Enum.MeshType.Sphere
sphereMesh.Parent = base
base.Anchored = true
base.Color = Color3.fromRGB(255, 255, 255)
base.Size = baseSize
base.Position = position
base.CanCollide = false
base.TopSurface = Enum.SurfaceType.SmoothNoOutlines
base.BottomSurface = Enum.SurfaceType.SmoothNoOutlines
cloud[#cloud + 1] = base
local container = Instance.new("Part")
container.Transparency = 0.75
container.Anchored = true
container.CanCollide = false
container.Position = base.Position
container.Size = containerSize
for i = 0, density do
local cloudPart = base:Clone()
sphereMesh:Clone().Parent = cloudPart
cloud[#cloud + 1] = cloudPart
end
if model then
cloudModel = Instance.new("Model")
cloudModel.Name = modelName
end
for i, part in pairs(cloud) do
part.CFrame = container.CFrame * CFrame.new(
Random.new():NextNumber(-container.Size.X/2, container.Size.X/2),
Random.new():NextNumber(-container.Size.Y/2, container.Size.Y/2),
Random.new():NextNumber(-container.Size.Z/2, container.Size.Z/2))
part.Transparency = math.abs(math.sin(i))
local size = Random.new():NextNumber(minSize, maxSize)
part.Size = Vector3.new(size, size, size)
if model then
part.Parent = cloudModel
cloudModel.Parent = parent
else
part.Parent = parent
end
end
container:Destroy()
if model then
return cloudModel
else
return cloud
end
end
return Cloud
Example of using it:
local Cloud = require(game.ReplicatedStorage.Cloud)
Cloud.Spawn(Vector3.new(20, 50, 30), Vector3.new(5, 5, 5), Vector3.new(15, 15, 50), 5, 10, 100, true, "Cloud", workspace)
Cloud.Spawn(Vector3.new(100, 100, 100), Vector3.new(10, 10, 10), Vector3.new(50, 25, 75), 10, 25, 75, true, "Cloud2", workspace)
Cloud.Spawn(Vector3.new(50, 50, 50), Vector3.new(1, 1, 1), Vector3.new(15, 15, 15), 1, 5, 50, true, "Cloud3", workspace)
The reason why this isn’t a resource is because Roblox already made clouds, and because other people made way better clouds that this, but it was a nice experience. The thing I’m the most proud of is using math.sin() to make seemingly random transparent cloud parts that look smooth.
If you have any feedback, please leave them down in the replies below!
EDIT: You can use the cloud generator if you want.
EDIT 2: I replaced the math.random() inside the section of the code to generate cloud parts inside the container to Random.new():NextNumber() so it can use decimals.
