Stop Repeating Yourself! Improve Your Code with Collection Service

You can also use the "for" syntax as an alternative to collection service, as you can multitask with it and it's very simple and not complicated at all to use. CollectionService is still pretty good though, but I prefer "for".

[@Someone-df3tv]

Exactly what I had been searching for. Thank you!!

[@Gavriasagmaeilll]

i suggest not trying to use workspace as a whole, because player models will exist in there too, and if their displayName is the same as a tag...then that changes a lot about the player in question

I don't use collection service, nor do I use dupe scripts. Instead I put them in a folder and for the loop I do folder:get children instead of collectionservice:get tagged but both work

[@xgodtoxi2978]

[@GnomeCode]

This works well until you want to organise your folder structure differently. What if your doors are inside a building? You would probably want them to be inside the folder/model for that building rather than in their own separate doors folder. CollectionService allows you to easily access all the tagged elements rather than relying on a specific folder layout.

[@buuild]

[@DrizzyB]

Can someone explain the original moving door script to me, specifically the "function MoveDoor(isOpen)" thing? I'm not understanding the argument of "isOpen" and how it's pertaining to the function. I know that arguments send information that is out of scope of a function to said function, but what information is "isOpen" sending? Does the "isOpen" attribute need to be applied to the model in order for the door to move? What about when the attribute is set to "not isOpen" after the proxim prompt is triggered? The door can still be moved after it's opened (closing the door). What does "local isOpen = model:GetAttribute("isOpen")" even mean?

[@gunipotys]

If the door should be open or not, if it should, then it reacts a way, if it shouldn’t, then it react another way. Also, the last line just get the value of the attribute.

[@georgepg3d854]

Its advanced scripting stuff and it seems like you dont understand it,but dont worry just practice more!And believe me studying better is better than studying more,so if you find scripting tutorials that you perfectly understand youre good to go!😊

How do you see the tags of an instance without a plugin? I use custom attributes and check its value for scripting. I can see attributes on the properties panel but idk where to easily find tags without plugin.

[@gerjovogelfotografie5826]

How does the script knows what ''model'' is? (parameter on 4:55)

[@Arab_GameZone1]

Because you told it to look at any model that has sliding door tag

[@Arab_GameZone1]

Also "model" is a variable so you can change it to what ever you want like name it "door"

[@Arab_GameZone1]

Sorry i thought you asking about the model that is in the for loop, in the parameter because you add the function movedoor to the for loop and told the script that you want it to work on the model and isopen using the parameter

Okay so, what makes me mad is that you didn't explain the for loop for this particular topic. Can you please tell me how that works for CollectionService?

[@Nahwap]

it basically gets every instance (doesn't matter if they are in the ServerStorage, ReplicatedStorage, Workspace, etc) with the tag you are looking for. For example, it's very good if you want to handle AI's because you dont need a single script inside every npc or every npc inside a single folder

Hey gnome, could you explain why do you use "isOpen" and "Close" or "Open" for proximity prompt text? Im assuming isOpen is a boolean attribute, but how does this works? The same happens at the color... Is it because, since its a boolean, if its true it will get the first parameter otherwise get the second? Appreciate, Thanks.

[@kristof0713]

or gives you the first value if its not nil or false and the second otherwise. true and "close" or "open" will give you close becuase true and "close" are both true values false and "close" or "open" turns into false or "open" because false and true -> false and if the first value is false or gives back the second one Idk if this made any sense Its lua's ternary operator

[@eliteengineer7340]

I dont use collection service , but i dont duplicate doors with scripts either, i would probably put parts to be replaced with the actual door asset when the game is launched, and used a module for the client to open doors

[@ahmoin]

I would create a separate folder with doors and use a for loop

[@chibisayori20]

That's actually what many games outside of Roblox do, they just have a door as an asset and when game is launched and the level loaded, it will spawn the door assets at their respective positions and have their logic setup by a class. Same goes for NPCs, interactables, player spawners and in-fact, Roblox's engine works same way since the basic parts and stuff like that are all handled by engine side, it just the logic/player stuff is handled on the Lua side. Tho setting up a system like that is kinda difficult, but i assume you can utilize the Package system they have to have all assets, scripts all placed in that package, so you only have to import it once, and all updates should affect every place that has your package.

[@eliteengineer7340]

wouldnt it just be enough to put a script in the server script service and get the parent of the proximityprompt to get the model. This way you dont need a tagging system and only one script (that also checks whether the proximity prompt parent is a door model.

[@chibisayori20]

@@Chaneb you can't have server overload if you intent your game to be played only in Studio 😉 jokes aside, alternative to this is just to put your model with script inside of a storage and Clone() it and parent it to a position you want it to be or use OOP but that's different thing.

you can apply collection service to more things than just doors with proximity prompts, like a group of items that are similar but only slightly different that you want to change

What does scipt.Parent mean?

[@oleNikolic]

It basically means the object that you put the script into, for example if you put a script into a part the script.Parent would be the part,and the script would be called the ‘Child’ of that part.

[@chibisayori20]

Just copy and paste them, or use Package system to make the door a package, so if you change the door's script, and update the changes it should update all doors in the place. You could also put the door in a storage service (ReplicatedStorage or ServerStorage) and clone them to a position on the map.
