If you're looking to build the next big fighting game, getting your roblox melee combat system script right is basically your most important task. It's the difference between a game that feels like a polished masterpiece and one that feels like a laggy, unresponsive mess. Think about the heavy hitters on the platform right now—games like Combat Warriors or Blox Fruits. They don't just have "attacks"; they have a "feel." That weight, the timing, and the satisfaction of a hit landing perfectly all come down to how you structure your code.
Building a combat system can seem intimidating if you're just staring at a blank script in Studio, but it's actually quite manageable once you break it down into logical chunks. You've got the animation, the hit detection, the client-server communication, and the "juice"—those little visual effects that make the player feel like they've actually done some damage.
The Foundation: Why You Can't Just Use .Touched
Let's get the biggest mistake out of the way first. A lot of beginners try to make a roblox melee combat system script by putting a .Touched event on a sword part. Don't do that. Just please, don't.
The .Touched event is notorious for being unreliable. Sometimes it fires ten times in a single frame; other times, your sword passes right through an enemy without registering a thing because the physics engine didn't catch the collision at high speeds. If you want a combat system that players actually enjoy, you need something more precise.
Most professional developers use something called "Raycasting" or "Spatial Queries." Essentially, instead of waiting for parts to bump into each other, the script "draws" invisible lines (rays) or shapes around the weapon as it moves. If one of those lines hits a player's hitbox, boom—damage dealt. It's faster, way more accurate, and much harder for exploiters to mess with.
The Client-Server Handshake
In Roblox, everything is a conversation between the player's computer (the Client) and Roblox's computer (the Server). For a combat script, this handshake is critical.
Here's the typical flow: 1. The player clicks their mouse. 2. The Client plays an animation immediately (so there's no lag for the player). 3. The Client fires a RemoteEvent to tell the Server, "Hey, I'm swinging my sword!" 4. The Server does some quick math to make sure the player isn't cheating (like checking if they're actually holding a sword or if they're swinging too fast). 5. The Server handles the hit detection and subtracts health from the victim.
If you try to do everything on the Server, the player will feel a delay between clicking and seeing the animation. That "input lag" is a total game-killer. By playing the animation on the Client first, the game feels "snappy," even if the server takes a few milliseconds to process the actual damage.
Writing the Logic: Animations and Debounces
When you start writing your roblox melee combat system script, you need to handle "debounces." That's just a fancy scripting term for a cooldown. Without a debounce, a player could spam their mouse and trigger fifty attacks in one second, which would probably crash your server or, at the very least, look ridiculous.
You'll also want to organize your animations. A good combat system usually has a "combo" chain—maybe three different swings that cycle through. You can store these in an array and use a counter variable to track which swing comes next. When the player clicks, you play animation #1; if they click again within a certain window, you move to #2. It makes the combat feel dynamic rather than repetitive.
Hit Detection That Actually Works
Since we're skipping the .Touched event, what should you use? I highly recommend looking into a community-made module like "Raycast Hitbox" by TeamSwordphin, or learning how to script your own WorldRoot:Raycast logic.
If you're scripting it yourself, you basically want to attach "attachments" to your sword model. During the swing, your script tracks the position of those attachments from the last frame to the current frame and draws a ray between them. If that ray intersects a character's limb, it's a hit. This method is incredibly robust because it accounts for the actual path the blade took through the air, meaning even if the player is spinning like a tornado, the hits will register exactly where they should.
Adding the "Juice" (VFX and Feedback)
A roblox melee combat system script that only subtracts health is boring. To make it feel "pro," you need visual and auditory feedback. This is what developers call "juice."
Think about adding: * Screen Shake: A tiny bit of camera wobble when a heavy hit connects. * Hit-stop: Briefly freezing the animation for a fraction of a second when it hits an enemy. This gives the illusion of physical resistance. * Particle Effects: A spark, a blood splatter (if that's your game's vibe), or a "slash" trail following the blade. * Sound Design: A "whoosh" for the swing and a "thwack" for the hit.
Most of these effects should be handled on the Client. Why? Because the Server doesn't need to see pretty particles; its only job is to manage the math. By keeping the VFX on the client side, you save server bandwidth and ensure the effects look smooth for the players.
Security: Keeping the Script Safe from Exploits
Let's talk about the elephant in the room: exploiters. If your roblox melee combat system script trusts the Client too much, someone will eventually write a script that tells your RemoteEvent they hit every player on the map at the same time.
You have to be a bit cynical when writing server-side code. Don't let the Client tell the Server how much damage to do. Instead, let the Client only say "I'm attacking." The Server should then check: * How long has it been since the last attack? (Is it too fast?) * Is the target within a reasonable distance? (No hitting people from across the map.) * Does the player actually have the weapon equipped?
By validating these things on the server, you make it much harder for someone to ruin the fun for everyone else.
Balancing and Fine-Tuning
Once you have the technical parts working, the rest is just "tuning." This is where you spend hours tweaking numbers. How long is the wind-up? How much "end-lag" is there after a swing? If a player misses, should they be punished with a longer cooldown?
This is the stage where you grab a friend, jump into a test server, and just hit each other for an hour. Pay attention to what feels frustrating. If it feels like you're "swinging through" people without hitting them, your raycasts might be too thin. If it feels like you're getting hit from too far away, your hitboxes might be too big.
Wrapping It Up
Creating a high-quality roblox melee combat system script is a journey of trial and error. You start with a simple click-to-swing mechanic, and then you layer on the complexity: the raycasting for accuracy, the remote events for networking, and the VFX for the "cool factor."
Don't worry if your first version feels a bit clunky. Even the biggest games on the platform went through dozens of iterations before they got that perfect "crunchy" combat feel. The key is to move away from basic physics collisions and start thinking about how to use rays and server validation to create something smooth and secure. Keep at it, keep testing, and before you know it, you'll have a combat system that players won't want to stop playing.
