ECS tips?

I'm going to try ECS. (JECS to be more precise) are there any tips on how to use it that I can use? Perhaps something should not be used, or, on the contrary, more than others. Maybe there is a template.

Solution:

go to the jecs project channel in ROSS and look through the pins in there

Humanoid Pathfinding jump issue

Notice how my pathfinding produces a two jump waypoints (marked in red). But it only jumps for 1 of them? Why is that?

Flamework TestEZ

Are there any examples of how to test services or controllers? I figure I'd have to use the Dependency macro, but I'm unsure how.

rbxts/Jabby Vide Dependency Causing Errors in React Code

I am in the process of porting over my react code over a different project that uses Jecs with Jabby, the code is fully functional on previous project, but the presence of Jabby with the Vide dependency is causing errors in the new one

Solution:

> Clear the content of index.d.ts in node_modules/@rbxts/vide/src (do NOT delete it, that will cause compile errors) > npx patch-package @rbxts/vide to automatically apply patch on later installs...

How to mock a library function in jest

I tried doing .spyOn to spy on the function but it didn't work. I don't think .mock works because it requires a module script, and roblox-ts strings will mess up its mockings

lapis readonly

I'm trying to create a wrapper function that simplifies reading and writing player data. However, I'm encountering an error that says: "attempt to modify readonly table." Lapis is returning the data as a readonly table, so I need a way to safely create a mutable copy of this data, modify it, and then send it back to be written. ...

Property 'values' does not exist on type 'Map<...>' change the 'lib' compiler option to 'es2015'+

Property 'values' does not exist on type 'Map<string, ReactElement<({ text, colour, valueInstance, maximumInstance, valueParam, maximumParam }: ValueBarProps) => Element, string | JSXElementConstructor<any>>>'. Do you need to change your target library? Try changing the 'lib' compiler option to 'es2015' or later.ts(2550)

i already changed that but the compiler doesn't recognize my changes to tsconfig!...

Solution:

Use https://www.npmjs.com/package/@rbxts/object-utils, then Object.values(yourMap)

I am trying to publish a package to @rbxts, but it says "<name>' is not in this registry.", I am apart of the org, I am signed into npm cli. What am I missing? https://github.com/MarcL01/RewindCSS - Ported RowindCSS to React "RewindCSS" My npm username is bigmarco254...

Solution:

SOLUTION: You have to submit your username to https://roblox-ts.com/join-org/success/ twice, once to get an invite email to join, after joining resubmit your username to https://roblox-ts.com/join-org/success/ and it "finalizes" it i guess
