How to start with plugins + react?

I am using the Comet framework + react to make a dss editor, but I can't seem to figure out how to create a view. From what I could gather from various sources I put together this code which I'm just trying to get some random UI to show up, but it is giving me a very big error that I cannot deduce any issue from: ```tsx // src/systems/main-system.ts import { Button, Dependency, GUI, OnEnd, OnInit, System, View } from "@rbxts/comet";...

Solution:

you prob could use flamework directly for plugins (if you're familliar with flamework) i set it up here https://github.com/Velover/FlameworkPluginTemplate...

Flamework Tips

Hello all, First with some context: I've been in the process of porting some games run by a group to use Rojo and even more recently I've been porting some code to use Typescript. I have familiarity with Typescript and React already. What I'm not familiar is Flamework and frameworks similar to it. ...

flamework not identifying service constructor

tl;dr services cannot be in shared I am using flamework for the first time and I'm not sure whether this is a conceptual misunderstanding or there is something I'm not seeing I have the following service (shared):...

Solution:

iirc services cant be made in shared, services is for server only, controllers is for client only, and components are for all three (client, shared, server). You'd have to make the SessionProvider service be serversided. Also for the SessionProvider you have to use the existing life-cycle events that flamework provides you with (onStart, onTick, etc...) to add logic to the listeners

How do you deal with multiple calls of FindFirstChild(), WaitForChild(), etc?

I'm new to both Rojo and Roblox-ts. One thing I noticed is that when I'm trying to access children of Instances is I'm having to repeatedly use FindFirstChild or WaitForChild or other methods and then having to use type casting or checking if the instance exists before finding the next child and so on and so forth Original luau code that looked like this: ```lua local track = self.Humanoid.Animator:LoadAnimation(ReplicatedStorage.Animations.Animation)...

How to observe client-side data changes in Charm without React?

I'm using Charm for state management in my Roblox game and have successfully set up server-client synchronization using the official example from the charm-example repository. The server-side implementation works perfectly with the provided example. However, I'm not using React on the client side and need guidance on the best practices for observing atom changes and updating the UI accordingly. Here's my current client-side code: ```...

Solution:

you can create a custom useAtom hook

Charm + ReadonlyMap Issue: forEach shows data but get() returns nil for same userId in atom sub

I'm having a weird issue with Charm in my RBXTS project on Roblox. I'm using an atom that holds a ReadonlyMap<number, PlayerData> for player states (where keys are UserIds as numbers). When a player joins, they're added to the map during hydration (I'm using charm-sync + tether), and I can see their initial state on the client-side (e.g., afk: false). After about 2 seconds, I update the local player's afk to true by creating a new map immutably and setting the atom. In my subscribe callback, I iterate over the state with forEach, and it correctly prints all entries, including my local UserId with the updated afk: true. However, in the same callback, when I manually do state.get(localPlayer.UserId), it returns nil every time; even though the UserId matches exactly what's shown in the iteration. ...
