Okay, I have a few questions about running code that shows up to everyone in a local script. I have a cannon, but the shooting function is currently in a local script so only the client can see the shells and damage. I will have to run server script code so everyone can see the shells and explosions.
How do I do this?
I tried using a module script, but it didn’t work since module script code ran from a LScript only is client sided.
Would remote events work?
Please tell me how to run server code in a local script.
Can I make global function on a server script?
Remote events would be your best bud here. You can use :FireAllClients() to replicate whatever event you wish to use to all clients in the game.
If it were me I would have two remotes (FireCannon, ReplicateShells) and my psuedo-code would look something like this:
- Use my remote to fire the cannon and do whatever server-sided checking is necessary
- Use the ReplicateShells remote and FireAllClients so that they all see whatever it is you plan to do
Wait what??? (Sorry im big noob.)
So I should make a remote event, when the player presses c.
then when the event is fired i run a script? However, the function to shoot has a LOT of variables and if i paste it in, i will have 129013120930139012 reference errors.
My shoot code:
function FireMachineGun(GunParent)
while FiringGun do
for _,v in pairs(GunParent:GetChildren()) do
if v:IsA("BasePart") then
if v.Name == "Cannon" then
local explosion = Instance.new("Explosion")
explosion.BlastRadius = 0
explosion.BlastPressure = 0
explosion.Position = v.Position
explosion.Parent = game.Workspace
local Part = Instance.new("Part")
Part.BrickColor = BrickColor.new("Crimson")
Part.Name = "Bullet"
Part.Material = Enum.Material.Neon
Part.CanCollide = false
Part.FormFactor = "Symmetric"
Part.Size = Vector3.new(40,40,24)
Part.BottomSurface = "Smooth"
Part.TopSurface = "Smooth"
local Mesh = Instance.new("BlockMesh")
Mesh.Parent = Part
Mesh.Scale = Vector3.new(1/25,1/25,1)
local BV = Instance.new("BodyVelocity")
BV.Parent = Part
BV.maxForce = Vector3.new(math.huge,math.huge,math.huge)
local PlaneTag = Instance.new("ObjectValue")
PlaneTag.Parent = Part
PlaneTag.Name = "PlaneTag"
PlaneTag.Value = Plane
local e = math.random(1,7)
local effective = math.random(1,21)
Part.Touched:connect(function(Object)
local blueSpaceplane = Object:FindFirstAncestor("Blue Spaceplane")
local blueInterceptor = Object:FindFirstAncestor("Blue Interceptor")
if (not Object:IsDescendantOf(Character)) then
local HitHumanoid = Object.Parent:findFirstChild("Humanoid")
if HitHumanoid then
HitHumanoid:TakeDamage(100)
local CreatorTag = Instance.new("ObjectValue")
CreatorTag.Name = "creator"
CreatorTag.Value = Player
CreatorTag.Parent = HitHumanoid
else if v.Name == 'Cannon' and (not HitHumanoid) and e == 2 and (blueSpaceplane or blueInterceptor) then
local explosion = Instance.new("Explosion")
explosion.BlastRadius = 5
explosion.BlastPressure = 500
explosion.Position = Object.Position
explosion.Parent = game.Workspace
end
end
end
end)
Part.Parent = game.Workspace
Part.CFrame = v.CFrame + v.CFrame.lookVector * 10
BV.velocity = (v.Velocity) + (Part.CFrame.lookVector * 2000) + (Vector3.new(0,0.15,0))
delay(3,function() Part:Destroy() end)
end
end
end
wait(GunTime2)
end
end
When it comes to actually making the code I’d be the worst person to ask. I’ve never personally worked with anything gun related although I hope to practice with raycasting and the physics engine soon.

Oh, okay. How would I transport the variables from my L-Script to the server script so it can shoot?
Also, can I check when the player has the C key down in a server script?
you just gotta get all the functions for creating the cannon ball part into the server

fireallclients is not needed, its just creating a part not an GUI, FireServer is a better choice imo

Can I get free robux local player in a server script?
Oops, I forgot that the server replicates and overrides any client replication. I guess you wouldn’t need an extra remote, you could do it all through that singular one while using FireServer
Can I get
free robuxlocal player in a server script?
Ha, unfortunately no. What you can do however is get the instance of the player who called the remote, which is an included argument for FireServer.

each plane waits until someone goes in, then it calls local player and stores it in a variable. Can i transfer the variable over to the server script?
yeah easily, the first thing you get in an function is the player, for example:
remotefunction.OnServerEvent:Connect(function(plr)
plr --this is the player
end)

Although plr is a parameter, and an event will be fired then the cannon fires in the SERVER SCRIPT not the local script, so i doubt function parameters would do much good. ( sorry if im wrong)
ofcourse! thats what remote evenst are for! for example:
--client firing the strings
local a = 1
event:FireServer(a)
--server receiving it
event.OnServerEvent:Connect(function(plr,a)
--plr will always be the first string the server get, then a

so that means i can transfer the thing over??? wow! can i ping you tomorrow since i gotta go to sleep. ( im a kid)

ofc, remote events are awsome

theres an lazy way of doing this, fire an event every second updating the cannonball on client side into the server side, making two balls, one for client and one for server

What I didn’t tell you was that the game was a dogfight game, so the cannons are aircraft cannons
@foxnoobkite, it’s not working.
I have a remote event called Shoot.
Here is the code.
Running code:(This is in a LocalScript)
function FireMachineGun(GunParent)
local Shoot = script.Parent.Shoot
while FiringGun do
Shoot:FireServer(GunParent,FiringGun,Plane,Character,Player)
end
end
Shooting Code:
(This in a script.(server))
local Shoot = script.Parent.Shoot
Shoot.OnServerEvent:Connect(function(GunParent,FiringGun,Plane,Character,Player,GunTime2)
for _,v in pairs(GunParent:GetChildren()) do
if v:IsA("Part") then
if v.Name == "Cannon" then
local explosion = Instance.new("Explosion")
explosion.BlastRadius = 0
explosion.BlastPressure = 0

if HitHumanoid then
HitHumanoid:TakeDamage(100)
local CreatorTag = Instance.new("ObjectValue")

CreatorTag.Parent = HitHumanoid
else if v.Name == 'Cannon' and (not HitHumanoid) and e == 2 and (enemyFighter or enemyInterceptor or enemyChaser) then
local explosion = Instance.new("Explosion")
explosion.BlastRadius = 5
explosion.BlastPressure = 500
explosion.Position = Object.Position
explosion.Parent = game.Workspace
end
end
end
end)
Part.Parent = game.Workspace
Part.CFrame = v.CFrame + v.CFrame.lookVector * 10
BV.velocity = (v.Velocity) + (Part.CFrame.lookVector * 2000) + (Vector3.new(0,0.15,0))
delay(3,function() Part:Destroy() end)
end
end
end
wait(GunTime2)
end)
When I press c, nothing happens but no errors.
