Velocity not working every time?
I'm making a little game and it's based around throwing, the way I throw it is with velocity, it works in single player test/ local server test but it does not work on team test or in the actual Roblox game?
I really don't know why it does this!
I used THIS as a base
Local script: (fires remote)
local mouse = game.Players.LocalPlayer:GetMouse();
local hrp = game.Players.LocalPlayer.CharacterAdded:Wait():WaitForChild("HumanoidRootPart");
local bball = game.ReplicatedStorage.Dodgeball
local rs = game:GetService("RunService").RenderStepped;
local MaxVelocity = 65 -- max speed
local aval = 0.00001 -- arc size
local UIS = game:GetService("UserInputService")
local MB1Held = false
local MB1Helt = 0
local MaxHeldDown = 5
UIS.InputBegan:Connect(function(input, gameProcessed)
if input.UserInputType == Enum.UserInputType.MouseButton1 then
MB1Held = true
MB1Helt = tick()
print("The left mouse button has been pressed!")
end
end)
local attach0 = Instance.new("Attachment", game.Workspace.Terrain);

-- calculate the bezier points
local c = .5*.5*.5;
local p3 = .5*g*t1*t1 + v0*t1 + x0;
local p2 = p3 - (g*t1*t1 + v0*t1)/3;
local p1 = (c*g*t1*t1 + 0.5*v0*t1 + x0 - c*(x0+p3))/(3*c) - p2;
-- the curve sizes
local curve0 = (p1 - x0).magnitude;
local curve1 = (p2 - p3).magnitude;
-- build the world CFrames for the attachments

Update:
it appears if you hold it down it acts as if you just tapped it? GIF I am going to see if any values are getting invalid on the server
Update 2:
I was testing and printing the values
print(plr)
print(hrp)
print(mousepos)
print(MB1Helt)
print(tick() - MB1Helt)
print(Held)
print(curve0)
as I was doing this I saw online 18 I redeclared "Held" and from that test it would be approx .3 milliseconds off, commenting out line 18 fixed it!
Line 18:
local Held = tick() - MB1Helt
