How to fix Raycasting script not dealing damage ?

Theres not much to explain the title pretty much sums it up but heres the script

01function fireBullet(start, target, maxLength)
02    --settings some constants
03    local directionVector = (target - start).unit
04    local direcitonCFrame = CFrame.new(start, start + directionVector)
05    --settings values that we're going to update throughout
06    local delta, lastTick, startTime = 0, tick(), tick()
07    local hit, position, lastPosition = nil, target, start
08    local totalDistance = 0
09    local function loop()
10        local ignore2 = {
11         character;
12         M4;
13         camera;
14         }
15        while not hit and totalDistance < maxLength do --basically stop if we hit our max or we hit something
16            delta = tick() - lastTick --get the time delta, aka time between last iteration and now
17            lastTick = tick() --set this to keep out delta calculations accurate
18            local travelDistance = delta * gunset.mvelocity --getting our distance for this iteration
19            --velocity being in studs per second
20            --Just a simple physics equation, distance = time * velocity
21            --Doing this makes for constant velocity, but not consistent ray distance
22            --all this does it get rid of potential lag influences really
23            travelDistance = travelDistance < 999 and travelDistance or 999 --just limiting our distance, this way is faster than math.min
24            totalDistance = totalDistance + travelDistance --just adding on to our total
25            local dropAmount = 9.81/2 * (tick() - startTime)^2 --gravity/2 * the square of our total time to get our bullet drop amount
26            local incremented = --see break down of what transformations are done below
27                direcitonCFrame * --start from our directionCFrame constant
28                CFrame.new(0, 0, -totalDistance) - --move forward our total distance
29                Vector3.new(0, dropAmount, 0) --move down based on our bullet drop amount
30            --doing this should give us an idea of where we want to be based on our calculations
31            local direction = CFrame.new(lastPosition, incremented.p).lookVector --getting a look vector from where we are, to where we want to be
32            --the rest you more or less had, fairly basic raycasting code
33            local ray = Ray.new(lastPosition, direction * travelDistance)
34            local hit,pos,normal,material = workspace:FindPartOnRayWithIgnoreList(ray,ignore2) --{workspace.Weapons, character, camera})
35            if hit then
36                handleBulletHit(hit,pos,normal,material)
37                break
38            end
39            lastPosition = position
40            wait(0) --would recommend waiting for one of the runservice events instead
41        end
42        if not hit then
43            print("Distance maxed out, we hit nothing")
44        end
45    end
46-- handle bullet part of script --
47 
48local handleBulletHit = function(hitPart, hitPoint, hitNormal,hitMaterial)
49if hitPart then
50    print(hitPart)
51    local humPart = character:FindFirstChild("HumanoidRootPart")
52    local targetHumPart = hitPart.Parent:FindFirstChild("HumanoidRootPart")
53    local hithumanoid =  hitPart.Parent:FindFirstChild("Humanoid")
54    if hithumanoid and targetHumPart and humPart and hithumanoid.Health > 0 then
55        if hitPart.Name == "LeftLowerArm" or hitPart.Name == "LeftUpperArm" or hitPart.Name == "RightLowerArm" or hitPart.Name == "RightUpperArm" then
56        remoteEvents.Hit:FireServer(hithumanoid,gunset.limbdamage,hitPart)  
57        ApplyTags(hithumanoid)
58    else
59    remoteEvents.Hit:FireServer(hithumanoid,gunset.damage,hitPart)  
60    ApplyTags(hithumanoid)

Do you actually define handleBulletHit after Line 36 or have you moved the function from somewhere while posting this script? Ankur_007 290 — 5y

This is pretty advanced script. I'm sure you can be more specific about the issue, if you wrote it... sleazel 1287 — 5y

i moved it fortune80 -4 — 5y

sorry if it is not clear enough but what im trying to say is for some reason is when it hits damage is not being dealt fortune80 -4 — 5y
