drag them

I build Roblox games and the systems behind them, games I've worked on have over a billion visits.

Seven years scripting, mostly self taught. I like problems that involve physics, anti-cheat, vehicles. Off Roblox I mess with electronics small robots, and simulations.

if(r < R_NS) continue;

           vr*Math.cos(th),
           vr*Math.sin(th)*Math.sin(phi) ]);

function spin(p){
  let x = p[0]*cosA - p[1]*sinA,
      y = p[0]*sinA + p[1]*cosA, z = p[2];
  return [ x*cosP + z*sinP, y, -x*sinP + z*cosP ];

Pulsar

A pulsar is what's left behind after a star dies. It's basically a giant ball of neutrons packed into a sphere, spinning hundreds of times every single second. Because it has a huge magnetic field, two blinding beams of radiation blast out of its magnetic poles. Every time the star spins.

To build this simulation, I used actual astrophysics formulas for visuals. The looping magnetic field lines are mapped using the standard magnetic dipole (yep similar to water molecules) equation r = R·sin²θ. As you move further out, the system hits a limit: the light cylinder. Derived from the Goldreich-Julian pulsar model (R = cT/2π), this marks the exact boundary where the spinning field lines would have to exceed the speed of light to keep up, causing them to tear open into space.

TOW Missile System 01 / 06
// things I've built
TOW Missile System→ A wire-guided missile that flies, steers, and reacts like the real thing.
FPS Gun System→ A full first-person shooter system, built out into a complete package.
SPAA System→ Anti-air vehicle with a turret that turns, locks on, and fires with bullet drop.
M1 Abrams System→ A full tank — drives, turret turns, fires. Built to feel heavy and real.
A Anti-Cheat System→ Catches impossible movement and holds up against real exploits.
3-Axis Soldering Arm→ A robot arm that lines up over a joint, drops down, and solders it on its own.
J J.A.R.V.I.S.→ A voice assistant in Python that listens, talks back, and sees through a camera.
