You can write your topic however you want, but you need to answer these questions:
What do you want to achieve? Keep it simple and clear!
I want to learn how to create a system which tweens parts to the tile you click, Unit being the part
What is the issue? Include screenshots / videos if possible!
I continue to get errors like “Unable to cast to Dictionary”
What solutions have you tried so far? Did you look for solutions on the Developer Hub?
Here is my LocalScript:
local Mouse = game.Players.LocalPlayer:GetMouse()
local Tiles = game.Workspace.Tiles
local RemoteEvent = game.ReplicatedStorage.RemoteEvent
Mouse.Button1Down:Connect(function()
print(Mouse.Target)
if Mouse.Target:IsA("BasePart") and Mouse.Target:IsDescendantOf(Tiles) then
local targetPosition = Mouse.Target.Position
RemoteEvent:FireServer(targetPosition)
end
end)
Here is my ServerScript:
local Unit = game.Workspace.Units.Unit
local RemoteEvent = game.ReplicatedStorage.RemoteEvent
RemoteEvent.OnServerEvent:Connect(function(targetPosition)
local tweenInfo = TweenInfo.new(1)
local tween = game:GetService("TweenService"):Create(Unit, tweenInfo, targetPosition)
tween:Play()
end)
Ah. Okay, I’ve got the problem. Where you put targetPosition as the third argument in TweenService:Create(), there is supposed to be a dictionary with all the properties and their new values. The ‘Unable to cast to dictionary’ error you are getting is caused by the fact that the method is expecting a dictionary, not a single value, and it can’t ‘cast’ (or convert) a single value to a dictionary. To learn more about this and how to do it, go to TweenService | Documentation - Roblox Creator Hub and read through the examples.
I tried something like this, but it returned the player instead, was I doing what you were saying? Sorry if I wasn’t, I’m so dumb I wasn’t able to comprehend what you said.
local Unit = game.Workspace.Units.Unit
local RemoteEvent = game.ReplicatedStorage.RemoteEvent
RemoteEvent.OnServerEvent:Connect(function(target)
local tweenInfo = TweenInfo.new(1)
local tween = game:GetService("TweenService"):Create(Unit, tweenInfo, { Position = Vector3.new(target.Position.X, 3, target.Position.Z) })
tween:Play()
end)
Remote events from Client → Server always pass the player that fires them first, and any extra data later. Change your arguments from (target) to (player, target)
