Please encode Lua code in the Lua block code tag (look for the Lua icon in the editor).

I never asked for the damn code mods so don't even try closing this. Just need some help with IK kinematics (aka dynamic movement) the problem is I don't know how the hell to make it and I get errors in the process of the code.

Code:

01wait(1)
02User = game.Players.LocalPlayer
03Humanoid = User.Character.Humanoid
04Torso = User.Character.LowerTorso
05L_Hip = Torso["Left Hip"]
06R_Hip = Torso["Right Hip"]
07 
08local step = game:GetService('RunService').RenderStepped;
09 
10function ArcTan(x, y)
11    r = math.atan(y / x)
12if x < 0 then
13    r = r + math.pi
14end
15return r
16end
17 
18vel = Vector3.new()
19while true do
20    step:wait()
21    local velVector = Vector3.new(Torso.Velocity.X,0,Torso.Velocity.Z);
22    if velVector.magnitude > 0 then
23        m = (vel - Torso.Velocity).magnitude / Humanoid.WalkSpeed
24        vel = (Torso.Velocity * m + vel * 2) / (m + 2)
25        v = Torso.CFrame:pointToObjectSpace(vel + Torso.Position)
26        L_a = ArcTan(v.x, -v.z)
27        R_a = 3.1416 - ArcTan(v.x, v.z)
28        L_Hip.C1 = CFrame.new(0, 1, 0)*CFrame.Angles(0, L_a+math.pi, 0)
29        R_Hip.C1 = CFrame.new(0, 1, 0)*CFrame.Angles(0, R_a+math.pi, 0)
30        L_Hip.C0 = CFrame.new(-0.5, -1, 0)*CFrame.Angles(0, L_a-math.pi, 0)
31        R_Hip.C0 = CFrame.new(0.5, -1, 0)*CFrame.Angles(0, R_a-math.pi, 0)
32        L_Hip.MaxVelocity = Torso.Velocity.magnitude / 100
33        R_Hip.MaxVelocity = Torso.Velocity.magnitude / 100
34    else
35        L_Hip.C1 = CFrame.new(0, 1, 0)*CFrame.Angles(0, -1.57, 0)
36        R_Hip.C1 = CFrame.new(0, 1, 0)*CFrame.Angles(0, 1.57, 0)
37        L_Hip.C0 = CFrame.new(-0.5, -1, 0)*CFrame.Angles(0, -1.57, 0)
38        R_Hip.C0 = CFrame.new(0.5, -1, 0)*CFrame.Angles(0, 1.57, 0)
39    end
40end

ok swearing obviously won't help your case Gey4Jesus69 2705 — 4y

i said hell? DayLighter_1995 8 — 4y

Could you maybe tone down getting my comments removed for asking help? DayLighter_1995 8 — 4y

"I get errors in the process of the code", yet you show no code. how do you expect to get help if you dont explain the issue? if you don't understand it at all, search the wiki and the devforum. your question is so unbelievably broad that you cant actually expect someone to answer it Gey4Jesus69 2705 — 4y

I did it. didn't you see? I did it on all of the posts I made? how'd you not see it? DayLighter_1995 8 — 4y

What I think is wrong is the Motor6D's DayLighter_1995 8 — 4y

yeah this code is totally on all your other posts Gey4Jesus69 2705 — 4y

It may have been a glitch. Don't wanna make a scene but your being a bit disrespectful.. DayLighter_1995 8 — 4y

*facepalm* Gey4Jesus69 2705 — 4y

Bro would you stop commenting I just wanted to make foot planting.. DayLighter_1995 8 — 4y

how 2 be a shitty mod DayLighter_1995 8 — 4y
