I don’t know how to use the coroutines, and I am getting nowhere with the wrapping function in the documentation. I think its not applicable to this scenario. I also don’t want to use the loop = true thing as I worry that will stop the loop for everyone. I say everyone as I noticed that the remote event will run two instances of the function when called twice, I worry that if one person changes the loop to false, person two will also get blocked. I will try to explain it again with the actual code this time.
game.ReplicatedStorage.StanceReseter.OnClientEvent:Connect(function(Player,Humanoid,Root,LHip,RHip)
if TruePlayer ~= Player then
Humanoid.CameraOffset = StanceOffset[1]
LHip.C0 = CF(-1, -1, 0) * CFANG(0, RAD(-90), 0)
LHip.C1 = CF(-0.5, 1, 0) * CFANG(0, RAD(-90), 0)
RHip.C0 = CF(1, -1, 0) * CFANG(RAD(-180), RAD(90), 0)
RHip.C1 = CF(0.5, 1, 0) * CFANG(RAD(-180), RAD(90), 0)
Root.C0 = CFANG(RAD(-90), 0, RAD(180))
end
end)
game.ReplicatedStorage.Stancer.OnClientEvent:Connect(function(Player,Name,Humanoid,Root,StanceChangeSpeed,Stance,PreviousStance,Neck,TCFM)
if TruePlayer ~= Player then
local PreviousOffset = Humanoid.CameraOffset
local PreviousRootP = Root.C0.p
local PreviousNeckP = Neck.C0.p
for X = 0, 90, 1.5 / StanceChangeSpeed do
local Alpha = Sine(X)
Humanoid.CameraOffset = PreviousOffset:lerp(StanceOffset[Stance+1], Alpha)
if Name == "Stand" then
if Stance ~= 0 then break end
Root.C0 = CF(PreviousRootP:lerp(VEC3(), Alpha)) * CFANG(RAD(-90), 0, RAD(180))
Neck.C0 = CF(PreviousNeckP:lerp(VEC3(0,1.5,0), Alpha))
elseif Name == "Crouch" then
if Stance ~= 1 then break end
Root.C0 = CF(PreviousRootP:lerp(VEC3(0, -1, 0), Alpha)) * CFANG(RAD(-90), 0, RAD(180))
if PreviousStance == 2 then
Neck.C0 = CF((PreviousNeckP*VEC3(1,1,-1)):lerp(VEC3(0,1.5,0), Alpha))
else
Neck.C0 = CF((PreviousNeckP):lerp(VEC3(0,1.5,0), Alpha))
end
elseif Name == "Prone" then
if Stance ~= 2 then break end
Root.C0 = CF(PreviousRootP:lerp(VEC3(0, -2.5, 1), Alpha)) * CFANG(RAD(180), 0, RAD(180))

I will provide detailed explanations for what the code is doing if you want so. But here is what is important:
When Stancer is called while the stancer loop is playing, I need it to pause the loop. then create a new one. This prevents two loops being played on one person, which causes jittering. (will show if you want to see it)
If stancereseter is called then I need it to break the stancer loop and animator loop.
I tried having the loops in coroutines, but yielding them did not work. I will continue to work on this while I wait for your response. Hear from you soon!
