Roblox API

Cluaupp uses the official engine. Spell the call in CL++ 0.3.2 / 0.3.3; look up members on create.roblox.com. #include <clpp/generated/instances.clh> lists flattened members: MeshPart has Size, CFrame, FindFirstChild, and WaitForChild, plus new MeshPart().

Handbook: Docs · Roblox in Cluaupp

#include <clpp/roblox.clh> is IntelliSense. The compiler ignores the header and emits real Luau.

Datatypes

part.Size = Vector3::new(8, 1, 8);
part.Position = Vector3::new(0, 10, 0);
part.CFrame = CFrame::lookAt(Vector3::new(0, 10, 0), Vector3::new(0, 10, -10));
part.Color = Color3::fromRGB(255, 0, 0);
frame.Size = UDim2::fromScale(1, 1);
auto material = Enum.Material.Plastic;

part.Size = Vector3.new(8, 1, 8)
part.Position = Vector3.new(0, 10, 0)
part.CFrame = CFrame.lookAt(Vector3.new(0, 10, 0), Vector3.new(0, 10, -10))
part.Color = Color3.fromRGB(255, 0, 0)
frame.Size = UDim2.fromScale(1, 1)
local material = Enum.Material.Plastic

Every enum is Enum.Name.Item. Services are GetService<Players>(). Instances are new MeshPart(), new Folder(parent), and mesh.FindFirstChild("x"). Binary payloads use Luau buffer (buffer::create, buffer::writeu32, buffer::readf64). Networking: write a .flare schema and include the generated Net.clh — see Flare.
