ez-bezier

Cubic bezier curve calculations made simple.

Usage

This example code moves a part up and down a bezier curve.

import { Bezier } from "@rbxts/ez-bezier";
import { Workspace, RunService } from "@rbxts/services";

// optionally change coefficients as last two parameters
const bezier = new Bezier(point0, point1, point2, point3);
const part = new Instance("Part");
part.Anchored = true;
part.Size = Vector3.one;
part.Parent = Workspace;

const speed = 1;
let increasing = false;
let t = 0;
RunService.RenderStepped.Connect(dt => {
  t = math.clamp(t + (increasing ? dt : -dt) * speed, 0, 1);
  if (increasing && t === 1)
    increasing = false;
  else if (!increasing && t === 0)
    increasing = true;

  // 't' is the progress along the curve
  part.CFrame = bezier.getCFrame(t);
});
