Upgrade Pet Level

Help and Feedback Scripting Support
#1

You can write your topic however you want, but you need to answer these questions:

  1. What do you want to achieve? Keep it simple and clear!
    I want to Modify my script, I just don’t know how. from simple pet system to level/upgrade pet via purchase that also includes rarity “Common” “Mid” and “Rare”
  2. What is the issue? Include screenshots / videos if possible!
    I want to upgrade pet level via ingame shop Purchase
    image
    when player purchase the initial Price(level1) (shown in image) the button will turn into “upgrade for $” (level2) if purchase again to lvl 3 button will turn into “Max upgrade”
  3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?

I tried a lot but seems my logic is far from what it should be.
this is my hierarchy in Replicated storage
image
I tried to make customizePet folder that includes the IntValue Level , level cost per upgrade then the Rarity so I can have a reference (but I think I’m doing it wrong) inside the lvl1 lvl2 lvl3 folder is the model per upgrade.

my script is not organized so I apologize in advance.

Please do not ask people to write entire scripts or design entire systems for you. If you can’t answer the three questions above, you should probably pick a different category.

#2

You need to introduce the concept of state into your code. There are many ways to do this, from table templates to metatables you just need to find some way to implement this thing called OOP for your shop items. Once that is done you are just storing the state of the objects and each player has their own different version of the state of all of the animals which gets saved to your datastore.

#3

Hmm, I’m not getting any of what you just told me. I’m a beginner, and I apologize for that. I just know how to make a simple pet system. I want this to be done by me, but it seems so complicated. It looks like I need to find someone to teach me how to do this kind of stuff.

#4

You just need to slow down and stop focusing on trying to make a pet system. Instead, you should study how data structures in lua work first and look at how other people coded pet systems and then come back to the problem

#5

There are many ways to do this. Many complicated ways. A un-complicated way would be to just make a new pet. When they “upgrade” they really are just getting a new version of that pet.
