FilterDescendantsInstances = Dec 14, 2022 · My brain is a bit dead right now and I can’t figure out how to add an offset to my raycast. Position, Vector3. You should instead be using CFrame. FilterDescendantsInstances = {start} params. CFrame * CFrame. Hello! So, I’ve been reading this article which solved one of my problem about the rotation of the gui. On several occasions, I’ve spent hours trying to figure out raycasts, all to no avail. You can most certainly use the lookVector, but you should multiply it by something like 100, or your ray will be like the boys when it’s cold outside: very short indeed. max(0, LookVector. That’s it. RemoteEvent. new() It seems that I have fixed the Issue, I took a look at the Roblox resource weapons and figured out how the shooting direction works. pi * 2 * (i / numerOfRays ) local direction = Vector3. Position, Do you want the raycast to go where the HumanoidRootPart is facing or where the camera is facing? I want the raycast to be in front of the player. Client side: local LookVector = workspace. How can I extend the raycast from the head in my code? aka. 5 studs (the forward cframe of the ai) BUT it Hello everyone, so when I do this: local ray = workspace:Raycast(gun. LookVector * Distance, Parameters) - From my understanding, whenever the LMB is clicked a ray is casted from the player’s camera to the mouse position and a “Bullet” is shot from the gun, some games shoot it from the Barrel, but most games cast it from the camera, cause it’s the best way to center a bullet, some games like Halo, use both methods for different situations, but it’s really your choice in I’m making an FPS game and I made bullets and raycast system. I dont really work with raycasting, cframes and stuff so yea --// VARS local UIS = game:GetService("UserInputService") local ReplicatedStorage = game:GetService("ReplicatedStorage") local PlayerService = game:GetService("Players") Hello. PrimaryPart. new(15, 24, 30) local node1_Position = Vector3. LookVector Make sure to multiply the vector by a number to make it go a distance 1. new(math. LookVector local ray = workspace:Raycast(start. Z * -ranX,ranY,lookvector. Main. Position, root. All I need is something to detect if there is a wall and maybe a part showing the look vector of the NPC. LookVector * distance but I With your current script, a ray is only computed once as the script executes. Why use Vector3 and now some angle in °. rad(Angle. The issue is it keeps returning nil even if I am looking at a part. lookVector * 25 -- To start the raycast a few studs before the projectile, to make sure the raycast isn't in the wall local final = Projectile. -- Perform the raycast. LookVector * range, params) Hello, I want to make it so that it raycast any objects in front of the player so that if I teleport the character in front, so character wouldn’t get stuck like a wall for example. FilterType = Enum. This is a simple example of how you can create a simple scene and create a raycast to pass through a part and hit another on the other side. Radius isn’t quite specific enough in this context. I am failing miserably. In the video you clearly see the gun was not moving at all and is being faced relatively towards my mouse which is facing straight when I move to the sides the raycasting is literally being casted to the sides even though I’m going based off LookVector as in I’m raycasting based off where the muzzle is facing. So that raises the question, is local direction = origin. local RaycastCheck = workspace:Raycast( Character:GetPivot(). Position part is what im refering to if raycast ~= nil local lookVector = Character:GetPivot(). How to use lookVector? Thanks in advance, -Meaxis local pivot = character:GetPivot() local origin = pivot. Position, Camera. Blacklist while true do wait(1) local raycastResult = game.

To fix this issue, move lines 5-6 inside the loop immediately after task. Parent local HitBox = Instance. CurrentCamera. This picture shows what I want I’m using a part’s look vector, but don’t know when the part moves, i want the raycast to move with it. Position, vector * 40, params) if ray and ray. If your directional vector is 1 stud on the Z axis, it will raycast from the origin until it reaches the directional vector which in this case is 0, 0, 1. while task. I can’t find anyone else with this issue either. -- this is how the bullet is moving local velocity = Instance. Here’s what I’ve achieved so far: local params = RaycastParams. Velocity = Vector3. local char = When using Raycast I always get confused so I better get the ray look vector then I multiply it by the distance I desire, like this: local node2_Position = Vector3. new(Vector3. LookVector is slightly smaller. Here is what the setup looks like: Here is a simple key for reference: Purple = Well, since you know what the inverse() of a CFrame is doing, essentially how it’s getting the offset by dot products:-- // Uses the code from your makeRay function local unitRay = camera:ViewportPointToRay(xVal,yVal) local cast = workspace:Raycast(unitRay. LookVector * 100 I won’t use Mouse. new() Parameters. Finally, to create a cone-like shape, the blue lines represent the I am trying to raycast from the player to detect what part they are looking at. local LookVector = Head. for Index, Player in pairs(Players:GetPlayers()) do.

The first issue is: The suspensions don’t really work, beucase on a terrain with rocks, the car gets stuck really easily, and on a grass terrain local Head = Character:FindFirstChild("Head") if not Head then return end local Parameters = RaycastParams. Position+ray. LookVector * 500) Where “gun” is a simple union that is in the shape of a gun held by the player, when I visualize the ray it shows that the length was not changed at all and it is at default (1) even though I clearly expanded the direction of the raycast to I don’t understand and that doesn’t really make sense. The green part is raycasted onto the slope, so you can use Raycast. You shouldn’t be using lookVector. LookVector * 500); The direction should be a vector relative to origin. Position + cast. Position, and the position in world space for origin + direction would be origin. When it comes to raycasting, these are usually used to measure how long the raycast goes for. Hit. Normal. IgnoreWater = true local wall = local rayresult = workspace:Raycast(camera. If you have the part then just use its lookVector, for the ray direction just do. I’ve looked up various solutions and none of them have worked. For example raycasting is one beem shooting from a beam but I would like to try and make it like such: If anyone understands what I have just said 🤣 As i told, the title says it all. local rayDirectionA = local direction = (Lidar_Range * CFrame.

I realize this is because of delays/ping, and I can’t find any good solution. Normal) should be used to set both the position and the LookVector at the same time. This means when you shoot the gun, it will shoot from the crosshair (at least in theory - it actually raycasts slightly above the crosshair, but i’ll get into that later). Position + cf. So, I have a raycast. Any help? while wait() do local ray = Ray. local rayLength = 5 part. new(0, 0, RandomOffset == 1 and -20 or 20), Params ) I want to know if there’s a wall next to a player, Feb 19, 2024 · So hello, im making a sort dfa system thingy and doing that i wanted to use raycasting.

The one you have there humanoidRootPart. LookVector local Greetings Developers, I am currently working on a top down shooter game and the script below is a serverscript inside a gun tool that fires and casts a ray to damage other humanoids every time a RemoteEvent fires. So here’s the key line for the problem local raycastResult = workspace:Raycast(rootPart. i. CFrame = CFrame. Parent local Torso = Character:FindFirstChild("Torso") if Torso then I recently found an open sourced gun system I want to use, I have modified, improved and fixed bugs on it, but theres a couple problem I dont know how to fix. LookVector * 1, VaultRaycastParameters) a one stud ray will not go very far, try casting it farther You can try this out: local function CheckFrontSight(start, target) local params = RaycastParams. new(0, 25, 0) is a pretty nonsensical direction. new("Weld") Weld2.

Position + root. LookVector, raycastParams) If I use lookVector, it only raycasts the direction the player is facing, not the I am really excited for how my viewmodel has come out. local rayresult = workspace:Raycast(camera. in your original code, if the origin of the raycast was at (0,0,0), and the lookvector was (1,0,0), and the orientation was (90,0,0), you would be trying to raycast to the position (91,0,0)). Raycast detects if something is hit and deals damage to it, while bullet is just there for the looks. Here’s an example of how it would work: local Params = RaycastParams. Instance. cos(angle), 0, math. Ok, now different example. If it doesn’t then, they aren’t.

LocalPlayer. if your LookVector is the black line in this image, you want to pick some velocity in the red cone: [image] I borrowed that I’m trying to make a top-down raycast go past my mouse and I got it to work but whenever I move it goes to idk where or why Just spawned: Moved: I’m not entirely sure why this is happening so any help would be appreciated local origin = root. lookAlong(cast. So sometimes if the path is slim, it will still be seen as clear while it isn’t due to the path not being thick enough. How to use lookVector? Thanks in advance, I have a raycast, and I am trying to make it go in a circular motion by using a vector3 value and adding on to it local Direction = (LookVector * 2000)+OffsetOrientation local Cast = workspace:Raycast(Origin, Direction) I’m making a wallrun system, I’m trying add a “jump off” mechanic that will make you jump diagonally away from the wall (forward and to the opposite side of the wall) Issue I’m having is applying a velocity at a diagonal angle from the velocity I’m already travelling in I guess I could use the lookVector of the hrp and add the rightVector normalizing depending on the Good morning (or night (or evening (or afternoon (or noon whichever))))! So, I’m recreating Geometry Dash, a 2D platformer/rhythm game, in Roblox. LookVector*2),part. The scenario: In this example, a raycast is projected Hello, I am making an ots weapon system and when testing the raycast and the rotation of the character towards the mouse position it does not work as planned the raycast continues for a long time when i point at Okay so, I have recently been trying to use Raycasting, or better said just experiment a bit with it. Blacklist local Result = Workspace:Raycast(Head. Whenever I run my code, It doesnt always come out the way I expect it. Position My code local WallCheckParms = RaycastParams. new("BodyVelocity") velocity. My goal is to know create bullet HIT effects, which requires me to get the position of the Raycast Results, I tried using RaycastResults. Position, direction) Good morning (or night (or evening (or afternoon (or noon whichever))))! So, I’m recreating Geometry Dash, a 2D platformer/rhythm game, in Roblox. My main problem now is the direction the raycast is supposed to go to. C1 = So I am trying to make a game where I detect where the player is looking towards. FilterType = Enumeration. new(origin. X*10, origin. clamp(VectorA:Dot(VectorB), -1, 1)) end local function IsDotProductWithin(CFrameA, CFrameB, FOV) local FovCheck = math. Blacklist castParams. rad(FOV) / 2 local Note that in Roblox this is very different because I think it returns a table of values. What I thought I wrote was working, but it only moves it globally. here is the script i have so far (only the important parts): local torso = script. Any possible ways to go about this would be appreciated! Note I don’t want to use any libraries such as FastCast, etc. for context, this ray shoots out from the characters back, but the issue here is why the new raycast returns nil whereas the old one returns a value, even if it’s the same ray? If the raycast returns something, then the player is on the ground. LookVector. LookVector * 5 local direction = pivot. Position, gun. new(1, 0, 0) would be a direction one stud to the right of origin. Something like this: so if the gun is close, it wont really miss but if its far then it has a way higher chance to miss I managed to do something similar, but the spread is different based on the distance. LookVector * length) to point in a particular Alright. But it also needs to face towards the red part which can be at any height above or below the green part. new(head. 1). The Rayasting from the player’s head part doesn’t seem to be working, the Raycast orientation is incorrect. I have decided to use RayCasts but I’ve ran into some issues. This is the script I used local Cam = workspace. local ray_object = workspace:Raycast(Camera. Move:Connect(function() local raycast = workspace:Raycast(mouse. acos(math. This is the cross product of these two I want to find out how to make these raycasts go in such an angle. With camera it is missing some of the edges. I’m trying to give them a sort of vision based entirely on raycasting, and trying to offset the lookvector so they have a large field of view. I have this raycast suspension system, I didn’t write it, I got help, because I tried watching tutorials and searching for tutorials, but nothing, I still can’t understand how they work. Position + (direction. LookVector * range, params)  · I’m wanting to to always check if there’s a wall to one side of a player I have this, but it seems to depend what direction the player is facing. FilterDescendantsInstances = {character, fx} local For the two setting variables, it will take lots of tuning to get exactly how you need. Well, it doesnt work like it has to do. I’m trying to create a shotgun effect. It checks the parts and rotates based on the results, then shoots more rays. UpVector * -15 local result = workspace:Raycast(origin, direction) if not result then return end -- And I’d suggest converting your code to the new version of RayCasting (yes I noticed that you said that even the new RayCast doesn’t work properly). LookVector * 500) Where “gun” is a simple union that is in the shape of a gun held by the player, when I visualize the ray it shows that the length was not changed at all and it is at default (1) even though I clearly expanded the direction of the raycast to So I have a moving part that I want a raycast to go straight forward on even if the part rotates, I am new to raycasting and wondering how I could go about this? Hey there so basically im making a beatdown for a game and for the barrage I added a weld with the hit box but instead of the dummy looking at me it looks away so im tryna figure out how to use this look vector on humrp with a weld but i cant. random(-75,75),0) local Result = workspace:Raycast(Player. local rayOrigin = player. The reason is that im utilizing a single ray raycast and then i noticed that there is something called “DotProduct()” How could i get to combine dotproduct into this code: local part = script. Activated:Connect(function() if debounce == false and Here is the full code I use for collision: (This code is ran whenever the projectile hits a wall) local begin = Projectile. LookVector*5000, RayCastType) -- ray has 5k limit length local intersection = result and result. LookVector?, It gives you the direction the Object is facing, Note that when you are using this, you have to multiply it a certain amount, because when raycasting, you have to account In this tutorial, you will learn how to make an object align to a surface while also pointing in some direction like this: An understanding of vectors and CFrame is required. No matter how character is rotated parts stay ie. new(mouse. Position local direction = camera. . The hitbox with camera. yAxis) EarthWall:PivotTo(cframe) You might need to adjust the cast’s normal I know there’s a topic exactly like this one, but it didn’t have anything marked as a solution and both of the answers didn’t work for me. Value)) local ray = workspace:Raycast(Origin. Normally people use (originPosition, targetPosition - originPosition) to point towards a specific position, or (originPosition, somePart. However, when creating a system to change the length of the beam by changing the position of an attachment, I have encountered an issue as I am unable to figure out how to convert the orientation of the red light (a MeshPart) to a Direction for the Hello, how could I “offset” raycast’s direction to achieve result shown on the picture below Black lines are raycasts and parts are where raycast ends. I’m making a gun system from scratch and the hit registration is a bit off. However, the rays always shoot in the same direction, regardless of the part’s orientation. This is my current code, but it does not work. LookVector with no success. LookVector local function onButton1Down() Remote:FireServer(LookVector) end As shown in this clip, the raycast only works for the left and front direction, how would I make it work for all directions? Script : local Part = script. Blacklist local vector = start. Right? I have a Raycast that starts at one position of an instance, follows the LookVector of the Instance's CFrame and then has parameters to stop it from hitting itself or particular bits around it. Making it so that the player doesn’t dash downward but can dash upward is a bit simpler: you would have to reconstruct the Vector3, like so. I don’t know how to do this. new(80, 20, 10) local Distance = 50 -- distance of ray local lookVector = (node2_Position - node1_Position). 2. local Velocity = Vector3. Exclude raycastParams. CurrentCamera: local unitRay = If I could literally answer your question completely disregarding performance then I would do it like this. I have the code to actually hit the target but now I want it to a miss. HumanoidRootPart --First raycast. Workspace:Raycast(Camera. Orientation local raycastResult = workspace:Raycast(rayOrigin, rayDirection, raycastParams) So why not use CFrame. I’m trying to make a system where an enemy launches a projectile at you that damages you. Always towards the direction they are walking. You can check what it actually returns on the docs page. LookVector * bulletSpeed velocity. UpVector”, because sometimes the upvector of the instance could be below or to the right of the ray’s normal vector. Which point would the raycast return the data of in this scenario: Assume this is already defined local ray = workspace:Raycast(root. Character. Position - Projectile. example code: local centerPoint = Vector3. FilterDescendantsInstances = {game. Part local raycastParams = RaycastParams. Position to find where to raycast to. Players. FilterType = I read all the posts I could find on this topic but all of them are about raycasting from the camera center to the mouse position I know that I can get the camera center by dividing both x and y of the camera ViewportSize by two but how would I get the position of where the camera is looking? I have something in mind which is using camera. Once cast, you can detect if the ray hits a BasePart or Terrain cell. new("Part") local RP = RaycastParams. new(lookvector. I don’t know how to use raycast to see if something is in front of the NPC like a wall to block it All I need is something to detect if there is a wall and maybe a part showing the look vector of the NPC local FieldOfView = 1 - (100 / 90 * 70 / 2) / 100 Sep 29, 2024 · After trying with the mouse’s LookVector, it somewhat works but it goes in weird directions. LookVector * 256 local raycastResult = workspace:Raycast(origin, direction, After trying with the mouse’s LookVector, it somewhat works but it goes in weird directions. Position, and not a world position where you want the ray to end up. Workspace:Raycast() instead, as game. LookVector * Range) if Raycast The second parameter of Raycast is the direction you want the ray to travel. Now I can’t just do “ray. FilterDescendantsInstances = {Eye1, Eye2, Torso, HRP Now, this all works perfectly fine but the problem I’m having is that one of the parts is too far away therefore the raycast doesnt reach it. Also, try setting up your raycast like this, where camera is equal to workspace. Here is a video on the subject if you would prefer to watch it instead: Unsure on how to get started with raycasting? You’re in the right place. task. Position + Vector3. So what I’m trying to find is that blue axis which I have local raycastParams = RaycastParams.
