I don’t understand any of this math so I’m hoping you do Prototrode (Nachiyen) August 20, 2023, 5:55pm I am working on a Bow tool and I need it to shoot arrows that don’t just go straight but have gravity actually effect it Right now I have a tween solution that tweens to the end I have no idea how else to do it Ideas? A modular, open-source, Proof-of-concept roblox projectile system utilizing ParticleEmitters as a graphical visualization. Maybe the angle calculations will be useful to you. The functions file contains more detailed documentation, located in src folder. Speed & Range I would like the arrow to have a given speed, and a limited distance range, say 100 So I have been working to create bezier curve projectiles and while I’ve had some luck, I’ve been facing an issue where the projectile will not run a fixed speed along the bezier curve, often slowing down and speeding up at different points across a curve, obviously for a projectile this motion is unrealistic (e. Here’s a video of the issue local plr = game. The problem is I am very new to scripting and I have no idea how to do it. I plan on using body/constraint movers, mainly BodyVelocity for linearly moving projectiles (e. I fully plan on using ray-casting to do so as it’s a weapon based projectile that’ll do damage to the players. It provides the functionality to attach objects to the simulation, allowing these objects to follow the path of the projectile as it moves through space. I’ve tried this DevForum on modeling a projectiles motion. Nogalo (Nogalo) December 3, 2020, So I’ve been trying to figure out how to make projectile hitboxes work. Part1 local Part2 = workspace. This is I am attempting to make a flare like projectile that runs on the client. Gravity,0) -- You can add gravity or even wind depending on your needs Velocity = Vector3. Character. Developer Forum | Roblox Change FastCast's projectile acceleration to achieve parabolic trajectory. My idea for the golfing portion is a camera on a golf ball, with an option to direct the ball to where you want it to shoot and a power bar of how quickly Hello! I have been searching for a solution on how to make a fast and instant hit-detection system for projectiles no matter how high your ping / latency is. nicemike40 (nicemike40) January 1, 2022, 9:30am #3. So when the client tries to fire a Projectile it sends a signal to the server, the server processes it and fires a remote to all clients, im Currently using SimpleCast, it does replicate the projectile aross all clients, but from other clients perspective they see the projectile stuck at it’s origin: Image (1 is the client who threw the projectile, it looks correct, but for other clients (2 What I want to achieve is a bullet tracer system just like in Phantom Forces. Ordinarily, the firing point that the trajectory simulation uses is calculated based on your mouse’s screen position, but since people can move relatively quickly, I’m attempting to create a sort of pseudo-aim-assist that hijacks your sent Since . I’d like to model the motion of a basketball like EgoMoose does in this tutorial. It’s actually 200m/s. Thank you – Example below. scripting, calculator. Here, s is speed, u is the initial speed, a is the acceleration due to gravity (196. I have a point A and a point B in workspace and I need a ball to be projected from point A to point B Any help would be appreciated 🙂 Developer Forum | Roblox How can I make this projectile motion. Viewed 2k times 2 . Players. My base code for the trajectory of the ball was from this post: yes i clickbait but the vid is REALlearn abt physics and kinematicsResources:FastCast - https://etithespir. Position - x0 - 0. Parent tool. 8m/s Speed at which the projectile is launched: 200m/s –Ignore the 230m/s. it/FastCastAPIDocs/Physics by Professor Dave - htt The projectile should never be used for hit detection. Some of my projectiles are affected by a gravity factor, so I cannot just use a single raycast to detect when a projectile will hit something. I need the to calculate the angle which I must fire the arrow. new(0, 0, 0) -- Position reference (The mouse's position or wherever you want the projectile to end) --<< Projecitle creation >>-- You can map this out using the projectile motion formula: p = p0 + vt - gt²/2. 5*g*t*t)/t This is the third post in a series about different vital parts about games revolving around combat and how to make them. One of the classes in the Fat Princess clone I’m making has the ability to fire a bow. I mean projectile goes to mouse point but not Moving objects are objects that move on one or more axes within the 3D space. You will also do in the server, for the sake of hitbox. FastCast is the module I use (although I usually modify it to my liking) and instead of a physics based projectile it instead CFrames a part every frame to give the illusion that the projectile is going to register the hit. also just to make sure but when you parent the ball to the workspace to be moved it is being positioned before or after that? from past experience I noticed that if the physics simulation takes place a frame or two before any bodymovers start Hey everyone, I’m trying to model the trajectory of a ball (sphere) with beams. Parent local hum = char:WaitForChild("Humanoid") local humRP = char:WaitForChild("HumanoidRootPart") local I’m currently making homing projectiles with the use of CFrames, because I want to avoid using Roblox Physics objects. RunService - Requires a lot of resource which will make game lag if there a lot of projectiles. 5*g*t*t)/t I believe you will need to combine projectile motion equation with for collision detection. Client cast vs Raycast hitbox. - amandania/Projectile Only reviews from users who have used this asset are shown Some details: Gravity 9. I saw this post by Modeling a projectile's motion Community Tutorials. However, it does not accurately display the path taken. Gravity, 0) local v0 = (enemy. When it actually spins so does its face and therefore the hit detection gets --g gravity, v velocity, t time, p initial position local function projectileMotionEquation(g, v, initialPosition, t) --See Ego Mooses tutorial on integrating projectile motion equation return 0. A community for Roblox, the free game building platform. Many game engines have this feature commonly known as Root Motion. The projectiles motion is in world space. I hope this module helps all the Bezier Curve Projectile - Community Resources - Developer Forum | Roblox Loading Hi I’m looking to create a projectile similar to the one shown below however utilising trails as opposed to particles – I’m unsure how I could create the circular motion as it travels; would this use Bezier Curves? I’ve attempted just simply rotating attachments in a 360 motion however had no such luck. Here's what it looks like. Activated:Connect(function() local projectile = script. kittyPGR (KittyPlays) December 8, 2022, Developer Forum | Roblox Help with Calculating Projectile Motion. Linear motion is movement along an axis. This is my code: if otherPart. We know that the derivative of position with respect to time is velocity and that the derivative of velocity with respect to time is acceleration. local cPos, lPos = projectile. 5 * g * t ^ 2 + v * t + initialPosition end local function Now initially, I have much experience with projectiles, raycasted, cframed, lerped, and even using body velocities, but I was wondering if there was a way to create a projectile method other than BV’s that would allow a trail to move freely as it does “naturally”(Meaning how it would move if you were to move a part with a trail in studio) over being CFramed or when it How to make a smooth projectile in roblox? Ask Question Asked 5 years, 4 months ago. – What this all does is create a projectile based on the information the client that originally fired a projectile gave and does this for all other clients. I want it to spin, and I can do that with tween or animation but in both cases it ACTUALLY spins and the way hit detection works is to send shapecast towards ninja star’s face. This behavior does not occur within roblox studio. Handle. 2, 0) -- Roblox gravity local timeStep = Hi, and thanks for reading in advance. Size = Vector3. Handle local plr = gam help making projectile face mouse. Anchored = true Developer Forum | Roblox Projectile physics collisions. Unit*100) Why is the described behavior happening and how can I make it never happen? Hey everyone, I recently ran into an issue that seems to be caused by a roblox update that has been causing my projectiles to randomly strike below their target when playing the game on a live server. Upon releasing, the bomb will automatically assume It contains Roblox Lua code that you can directly use. This movement feels weighted and it You can write your topic however you want, but you need to answer these questions: What do you want to achieve? Keep it simple and clear! I am attempting to make a cannon that follows an arc using the quadratic equation What is the issue? Include screenshots / videos if possible! The current height prints out 240ish at t-0 instead of 0. - 1Axen/Secure-Cast. Here’s the code I am using: local fire = nil local flare = Instance. I I’ve tailored around with Tweening and Raycasting in the past - The issue I encountered with this is accounting for object, Players etc. For example, when a block has linear Discover millions of assets made by the Roblox community to accelerate any creation task. I have been looking over coding examples from other developers on the forum from the past, and I came across this example by @Oseday: local Part1 = workspace. This module can return the position of a point at any interval t, where 0 ≤ t ≤ 1, and is able to return the derivative of the Bezier Curve at any interval t, where 0 ≤ t ≤ 1. The projectile moves using BodyMovers at high speed, and I need it to be able to hit a surface and bounce back off it without losing momentum at a realistic angle. Each client is already handling their own projectile collisions with raycasts, but I would assume that Projectile Motion. local Motion = Instance. Nogalo (Nogalo) December 3, 2020, 7:31am #1. I have tried using this Devforum post (Modeling a projectile's motion) made by @EgoMoose. Using the built-in power of Roblox's simulation engine, you can make objects move and interact with their Dec 11, 2024 · Discover millions of assets made by the Roblox community to accelerate any creation task. Thus, the reverse is also true, the integral of acceleration with respect to time is velocity and the integral of velocity with This code was largely put together using projectile motion code from an old Roblox tool (slingshot There are alternatives, such as FastCast which you should use if you don’t need to physically model the bullet, but just compute it’s trajectory. Name == "Bouncer" then local move = Instance. Scripting Support. Also, the character should be able to move where they’re looking in You can write your topic however you want, but you need to answer these questions: What do you want to achieve? I am using a remote event and making a beam that creates projectile motion when the player aims. This function should work:--g gravity, v velocity, t time, p initial position local function projectileMotionEquation(g, v, initialPosition, t) --See Ego Mooses tutorial on integrating projectile motion equation return 0. Since velocity is split into 2 components, if velocity changes or is applied horizontally, that horizonal velocity or force does not affect the vertical force or velocity, and vice versa. jdobcypukiqpsskeeiuwebbhbkppzehmjcyjpfufgkesjpvngsxx
