Roblox Simulator Pet Follow Script

Getting your roblox simulator pet follow script working smoothly is one of those things that looks easy on the surface but can get a little tricky once you dive into the details. If you've spent any time playing big hits like Pet Simulator 99 or any of the countless "clicker" games out there, you know that the pets are the heart of the experience. They aren't just there for decoration; they follow you around, give you multipliers, and honestly, they just make the game feel more alive.

But how do you actually get a little cube or a low-poly dragon to trail behind a player without it glitching through the floor or flying off into the stratosphere? It's all about the math and the physics working together in Roblox Studio.

Why the Follow Script is Such a Big Deal

In a simulator, the pet is the player's constant companion. If the movement feels clunky or robotic, it breaks the immersion. A solid roblox simulator pet follow script needs to handle a few things: it has to keep a specific distance, it needs to rotate to face the same way as the player (or at least look where it's going), and it needs to move smoothly.

If you just teleport the pet to the player's position every frame, it'll look jittery. If you use basic physics without any constraints, the pet might get stuck behind a wall or start spinning uncontrollably because it bumped into a pebble. We want that "floaty" yet responsive feel that makes the pet feel like it's actually hovering or walking behind you.

Setting Up Your Pet Model

Before we even touch the script, your pet model needs to be set up correctly. Most people use a simple Part or a MeshPart.

  1. Group your pet: Make sure the pet is a Model.
  2. PrimaryPart: Set a "PrimaryPart" (usually the main body).
  3. CanCollide: Usually, you want to turn CanCollide off for the pet parts. If the pet hits the player, it can cause some really weird physics glitches where the player gets launched into the air.
  4. Massless: Check the Massless property in the Properties window for all parts of the pet. This ensures the pet doesn't weigh the player down if they are connected by any physical constraints.

Choosing Your Movement Method

There are generally two ways to handle a roblox simulator pet follow script: the "Old Way" using BodyMovers and the "New Way" using MoverConstraints.

The Old Way (BodyPosition and BodyGyro)

For a long time, we used BodyPosition and BodyGyro. They're technically deprecated now, but plenty of developers still use them because they're honestly pretty easy to understand. BodyPosition pulls the pet toward a coordinate, and BodyGyro keeps it upright.

The New Way (AlignPosition and AlignOrientation)

Roblox now pushes AlignPosition and AlignOrientation. These are more stable and work better with the modern physics engine. They require two "Attachments"—one on the pet and one on the player (or a target position).

Writing the Core Follow Logic

To get started, you'll usually want a script inside ServerScriptService or even a LocalScript if you want the movement to be buttery smooth on the client side. Let's talk about the logic behind a basic script.

You'll want to use RunService.Heartbeat. This is a loop that runs every single frame after the physics have been calculated. Inside this loop, you're basically telling the pet: "Look at where the player is, calculate a spot about 5 studs behind them, and move there."

Here's a simplified breakdown of what that looks like in code logic: * Find the player's Character and their HumanoidRootPart. * Define an offset (e.g., 5 studs back and 2 studs to the right). * Use CFrame math to calculate that target position in world space. * Update the pet's position/velocity to move toward that target.

Handling Multiple Pets

This is where things get a bit more interesting. If a player has one pet, it can just sit behind them. But what if they have ten? You can't have ten pets all trying to occupy the exact same coordinate—they'll clip through each other and look like a mess.

To solve this, your roblox simulator pet follow script needs a bit of "formation" logic. Instead of every pet following the player's exact back, you assign each pet an index (Pet 1, Pet 2, Pet 3). You then use some basic trigonometry (sine and cosine are your friends here!) to arrange them in a circle or a grid behind the player.

For example, you could arrange them in a semi-circle. As the player moves, the pets maintain their spot in that semi-circle. It looks professional and keeps the screen from looking cluttered.

Making it Feel "Juicy"

A stiff pet is a boring pet. To make your simulator stand out, you want the pets to have some personality. Even a simple "bobbing" motion makes a huge difference.

You can achieve this by adding a small offset to the Y-axis using math.sin(tick() * speed). This creates a smooth up-and-down motion that makes it look like the pet is hovering. You can also add a slight tilt when the pet moves forward or turns. It's these small details that make a roblox simulator pet follow script go from "okay" to "top-tier."

Common Pitfalls to Avoid

I've seen a lot of developers struggle with their pets disappearing or acting crazy. Here are a few things to keep an eye on:

  • Anchoring: Make sure your pet's PrimaryPart is NOT anchored. If it's anchored, physics-based movement scripts won't move it.
  • Network Ownership: This is a big one. If the server is calculating the pet movement, there might be a delay (lag). For the smoothest experience, you often want to set the Network Ownership of the pet to the player. This lets the player's computer handle the physics, making the pet feel responsive.
  • The "Flying" Glitch: If your pet has CanCollide turned on and it hits the player's legs, the physics engine might get confused and launch the player into the sky. Always double-check your collision groups!

Putting it All Together

When you're finally building your roblox simulator pet follow script, start simple. Get one part to follow you. Once that works, add the smoothing. Once that's smooth, add the rotations. Once the rotations look good, add the multiple-pet math.

Don't be afraid to experiment with different values for "Responsiveness" or "Speed." Sometimes a pet that lags slightly behind feels more natural than one that is glued to the player's hip. It's all about the "feel" of your specific game.

Final Thoughts

Creating a pet system is one of the most rewarding parts of making a Roblox simulator. It's the moment your game starts feeling like a real product. While the scripting can seem daunting if you're new to CFrame and Vector3 math, just remember that you're essentially just telling an object to chase a point in space.

Keep your code clean, use the modern MoverConstraints if you can, and always test with multiple pets to make sure your formation logic holds up. Before you know it, you'll have a loyal army of pets trailing behind your players, making your simulator feel exactly how it should. Happy scripting!
