Trajectory of a snowball not working correctly?
Asked by

I'm trying to use the equation that describes the trajectory of a projectile for a snowball in my game. I think I put the equation correctly but it's not working.
Server Script:
01 | eventsFolder.FireSnowball.OnServerEvent:Connect(function(player,angle,mousePos,playerPos,vectorPos,velocity,height,vector,playerCFrame) |
03 | local breakBool = false |
05 | local snowball = game.ServerStorage.Snowball.Handle:Clone() |
06 | snowball.Parent = game.Workspace |
07 | snowball.Position = playerPos |
08 | snowball.Name = "Snowball" |
09 | local part = Instance.new("Part") |
10 | part.Parent = game.Workspace |
12 | part.CanCollide = false |
14 | part.Position = vectorPos |
18 | snowball.Touched:Connect(function(hit) |
19 | if hit.Parent ~= player and hit.Parent ~= game.Workspace then |
24 | if hit.Parent:FindFirstChild("Humanoid") then |
25 | hit.Parent.Humanoid.Health = hit.Parent.Humanoid.Health - 20 |
30 | if breakBool == true then |
34 | local cos = math.cos(angle) |
35 | local xAxis = (velocity/vector.Magnitude)*i |
36 | local lerp = playerCFrame:Lerp(part.CFrame,xAxis) |
37 | local x, y, z, m11, m12, m13, m21, m22, m23, m31, m32, m33 = lerp:components() |
38 | local newCF = CFrame.new(x, height + y + xAxis*math.tan(angle)-(9.8*(xAxis*xAxis)/(2*(velocity*cos)*(velocity*cos))), z, m11, m12, m13, m21, m22, m23, m31, m32, m33) |
39 | snowball.CFrame = var2 |
Localscript(this is working):
01 | local button = script.Parent |
02 | local event = game.ReplicatedStorage.RemoteEvents.ToggleSnowball |
03 | local event2 = game.ReplicatedStorage.RemoteEvents.FireSnowball |
05 | local border = button.Parent.Outline |
06 | local player = game.Players.LocalPlayer |
07 | local character = player.Character |
08 | local mouse = player:GetMouse() |
11 | button.MouseButton1Down:Connect(function(player) |
13 | if not character or not character.Parent then |
14 | character = player.CharacterAdded:wait() |
17 | if border.Visible == false then |
21 | for i,gui in pairs(button.Parent.Parent:GetChildren()) do |
22 | if gui:FindFirstChild("Outline") then |
23 | if gui.Name ~= button.Parent.Name then |
24 | gui.Outline.Visible = false |
29 | event:FireServer(player) |
31 | while border.Visible == true do |
33 | mouse.Button1Down:Connect(function() |
34 | if debounce == true then |
36 | local mousePos = mouse.Hit.p |
37 | local mouseVector = mousePos - character.HumanoidRootPart.Position |
38 | local parallelVector = Vector3.new(mousePos.X,character.HumanoidRootPart.Position.Y,mousePos.Z) - character.HumanoidRootPart.Position |
39 | local angle = math.deg(math.acos(mouseVector:Dot(parallelVector)/(mouseVector.Magnitude * parallelVector.Magnitude) ) ) |
40 | local height = character.HumanoidRootPart.Position.Y |
41 | event2:FireServer(angle,mousePos,character.HumanoidRootPart.Position,Vector3.new(mousePos.X,character.HumanoidRootPart.Position.Y,mousePos.Z),velocity,height,parallelVector + character.HumanoidRootPart.Position,character.HumanoidRootPart.CFrame) |
51 | event:FireServer(player) |
53 | border.Visible = false |
The snowball just ends up behaving the same way no matter what angle I throw it at.
Also, here is the equation for the trajectory of a projectile:
y = h + x * tan(?) - g * x² / 2 * V?² * cos²(?)
Thanks! (Also sorry for the lack of comments)
