If you're trying to build a JoJo-themed game, getting a functional roblox stand ability script up and running is basically your biggest hurdle. It's one thing to have a cool-looking model follow you around, but making it actually do something—like punching at high speeds or stopping time—is where the real challenge starts. I've seen a lot of people get stuck just trying to make the stand appear, so let's break down how this stuff actually works without making it overly complicated.
Getting the Foundation Right
Before you even touch a line of code, you have to understand the relationship between the player and the stand. In most Roblox games, the stand isn't just a part of the character; it's a separate model that needs to be toggled. When you're writing a roblox stand ability script, you're usually dealing with a "Summon" state.
Usually, you'll want a BoolValue inside the player or their character called "StandActive." This is your gatekeeper. If it's false, your ability scripts shouldn't run. If it's true, the stand is out and ready to rumble. It sounds simple, but you'd be surprised how many bugs happen because someone forgot to check if the stand was actually summoned before letting a player spam their "Ora Ora" barrage.
You're also going to be working heavily with RemoteEvents. Since the player is the one pressing the keys (Client), but the damage and the stand's position need to be seen by everyone else (Server), you've got to bridge that gap. If you try to do everything in a LocalScript, you'll be the only one seeing your stand, which makes for a pretty lonely fighting game.
The Magic Behind Summoning Your Stand
The first part of any decent roblox stand ability script is the summon mechanic. Usually, we bind this to the 'Q' key. When the player hits Q, the client sends a signal to the server. The server then checks: "Does this guy already have a stand out?"
If not, the server clones the stand model from ServerStorage, parents it to the character, and uses a WeldConstraint or an AlignPosition to keep it hovering behind the player's shoulder. Personally, I prefer using AlignPosition and AlignOrientation because it gives the stand that floaty, ghostly movement. If you just weld it, the stand looks stiff, like it's a piece of plastic glued to your back.
Once the model is there, you need to trigger an animation. A stand appearing out of thin air with a "T-pose" looks terrible. You need a summoning animation for the character and a "spawn" animation for the stand. This is where your script calls LoadAnimation on both the humanoid of the player and the humanoid of the stand.
Making the Barrage Feel Powerful
Let's talk about the bread and butter of any stand: the barrage. This is usually the most requested feature for a roblox stand ability script. To make a barrage feel "heavy" and impactful, you can't just play an animation and call it a day.
You need a loop. Inside that loop, you're doing a few things: 1. Playing the punching animation. 2. Creating "ghost" arms or punch effects to make it look faster than it actually is. 3. Running a hitbox check.
For the hitbox, I'd suggest using GetPartBoundsInBox or a Raycast. Old-school scripts used Touch events, but those are notoriously unreliable and laggy. You want the script to check for any parts belonging to another player within a small area in front of the stand. If it finds someone, it subtracts health.
To prevent the game from crashing or the player from dealing infinite damage, you have to use a "debounce" or a cooldown. Even a tiny wait like task.wait(0.1) between punches makes a huge difference. Also, don't forget the sound effects. A barrage without the "ORA ORA" or "MUDA MUDA" sounds is just sad.
Scripting Unique Stand Abilities
Once you've got the basics down, you'll want to add some flavor. This is where the roblox stand ability script gets interesting. Every stand needs a "gimmick."
Take a "Time Stop" ability, for example. This is arguably the hardest thing to script because you have to literally pause the game world for everyone except the user. You're not actually pausing the server; instead, you're usually anchoring every part in the Workspace and disabling the scripts or movement of other players. Then, you use a massive color correction effect (like turning the screen grayscale) to give it that visual punch.
Or maybe you want a projectile, like firing a finger nail or a stone. For that, you'd use LinearVelocity to propel a part forward. You'd also need a "Touched" or "Raycast" hit detection on that projectile so it explodes or deals damage when it hits a wall or an enemy. The key here is cleanup. If your script creates fifty projectiles and never deletes them, your server is going to die a slow, painful death. Always use Debris:AddItem() to clean up after yourself.
Keeping Your Script Clean and Lag-Free
One thing I see a lot of beginners do is cramming 2,000 lines of code into a single script. Please, don't do that. It makes debugging a nightmare. If your roblox stand ability script isn't working, you don't want to be scrolling for twenty minutes to find a missing comma.
Use ModuleScripts. Put your main stand logic—like how to summon it or how the damage is calculated—in a module. Then, your main server script can just "require" that module and call specific functions. It keeps everything organized. For example, you can have a module for "StandActions" and another for "VFX."
Also, be mindful of the server's workload. If you have twenty players all using stands with high-speed barrages, that's a lot of hit detection. Try to offload as much visual stuff as possible to the client. The server should handle the "math" (is the player close enough to hit? how much health is left?), while the client handles the "pretty stuff" (particle effects, screen shakes, and sounds).
Learning from the Community
Honestly, nobody learns how to write a roblox stand ability script in a vacuum. Most of us started by looking at free models in the toolbox, seeing how they were broken, and trying to fix them. If you're stuck, the Roblox Developer Forum and various scripting Discords are gold mines.
Don't just copy-paste code, though. If you find a script that works, take it apart. Figure out why the programmer used a Task.spawn there or why they chose Magnitude over a Region3 check. That's how you actually get good.
Building a stand system is a big project, and it's probably going to break a dozen times before it works. You'll deal with stands getting stuck in walls, animations not playing, and players flying across the map because of a physics glitch. It's all part of the process.
Final Thoughts
At the end of the day, a great roblox stand ability script is all about the "feel." You can have the most complex code in the world, but if the stand doesn't respond instantly when you press a key, or if the punches don't feel like they have weight, players won't enjoy it. Focus on the timing, the sounds, and the visual feedback.
Start small. Get the summon working first. Then move to a single punch. Then the barrage. Before you know it, you'll have a full-blown combat system that looks like it belongs in a top-tier anime game. Just keep testing, keep breaking things, and most importantly, keep coding. It gets easier the more you do it, I promise.
