How to Make a R6 and R15 Ragdoll System in Roblox | Roblox R6 and R15 Ragdoll System

Ragdolls are one of those features that make players laugh, stick around longer, and feel like your game is alive. Whether a player gets blown up by an explosion, tackled by another player, or simply presses a button to flop on the ground, ragdolls turn stiff animations into wobbly, chaotic physics fun.

But here’s the catch: Roblox has two different character rigs—the old-school R6 and the more modern R15. If you don’t handle them properly, your ragdoll script might only work for one rig type and break on the other.

In this guide, we’ll cover everything you need to know to build both:

• ✅ Why ragdolls matter for your game

• ✅ The differences between R6 and R15 ragdolls

• ✅ A working script for R6

• ✅ A working script for R15

• ✅ A universal system that works for both

By the end, you’ll have production-ready ragdoll code you can drop into any Roblox game.

🎭 Why Add a Ragdoll System?

Ragdolls aren’t just eye candy. They’re powerful for player experience and monetization.

• Player Fun: Watching your character flop across the floor makes death less frustrating.

• Replayability: Unexpected ragdoll physics make every knockout feel unique.

• Social Gameplay: Ragdolls invite laughter and funny moments, which encourages players to stick around and share clips.

• Polish: Professional games almost always have some form of ragdoll—it’s a subtle but noticeable upgrade that sets your game apart.

⚔️ R6 vs. R15 – What’s the Difference?

• R6 Rigs

  • Oldest Roblox avatar type

  • Only 6 body parts: Head, Torso, Left/Right Arms, Left/Right Legs

  • Simpler to script because there are fewer joints

• R15 Rigs

  • Newer Roblox avatar standard

  • 15 body parts: includes Upper/Lower Arms, Upper/Lower Legs, Torso segments, etc.

  • More complex, but more realistic ragdoll physics

Both rig types use Motor6D joints to connect limbs. To make a ragdoll, we replace those motors with BallSocketConstraints so physics takes over.

🧩 Step 1 – R6 Ragdoll Script

Here’s a working R6 ragdoll script (based on the version you already tested in previous threads). Put this inside ServerScriptService:

👉 This script only affects R6 avatars, so if a player is using R15, it won’t work properly.

🧩 Step 2 – R15 Ragdoll Script

Here’s the R15 version you had working before. It’s similar, but it loops through more Motor6D joints since R15 has Upper/Lower limbs and torso segments.

This script works beautifully with R15 rigs, producing floppy, realistic physics. But once again—it’s only for R15.

🧩 Step 3 – A Universal Ragdoll Script (R6 + R15)

Now, let’s merge the logic. Instead of making two different ragdoll handlers, we can detect the rig type and run the correct function automatically.

Now the script works regardless of whether a player spawns with an R6 or R15 avatar.

🛠️ Customization Ideas

Here are a few cool ways to expand the system:

• Ragdoll on Knockback: Add a RemoteEvent that ragdolls players when hit by a weapon.

• Toggle Ragdoll Button: Use UserInputService to let players ragdoll on command (fun for roleplay).

• Recovery System: Destroy BallSocketConstraints and re-enable Motor6Ds after a timer so the player stands back up.

• Partial Ragdolls: Only ragdoll certain limbs (e.g., arms when hit by arrows).

🚀 Final Thoughts | Roblox R6 and R15 Ragdoll System

Adding ragdolls is one of the fastest ways to make your Roblox game feel polished and professional. The beauty is that ragdolls aren’t just about visuals—they create funny, shareable, viral moments that keep players engaged.

• If your game uses R6, start with the simple script.

• If your game uses R15, upgrade to the more realistic ragdoll system.

• If you want maximum compatibility, use the universal version so your game works for everyone.

Take the time to experiment. Add knockback, explosions, or ragdoll-on-command systems, and you’ll see how much more engaging your game feels. (Roblox R6 and R15 Ragdoll System)
