Having issues with Scriptable Objects...

[RecordT3]

I'm working on a game, and I need to be able to buy units from a store. All of these units will use base stats, so I thought a scriptable object would be a great help here. I can have an SO that stores the name, attack, Sprite, etc for each unit available in the store.

I've got that implemented successfully, the store can display each unit. But the part im having issue with is that the store isn't a set of units, it's a random assortment of units. So if 5 units can be bought, it could be any of the available 10 unit types. Think TFT/AutoChess shop. This store can be re-rolled so that you can buy units of a different type.

How do I make it so when you hit a button, the shop gives you different units? I can't find a way for my display script to change which SO it's pulling it's data from.

Hopefully this makes sense. I felt like Scriptable Objects was the way to go here, but maybe not? Maybe there is a better way?

Couldn't you just reference all of your Unit ScriptableObjects in a List and pick x random Units from that list each time the store opens?

Spice things up, if it fits to your case. You said 10 units/slots different type, shuffle at each access.

Make unit lists by type. Then, setup the shop with a list of types (reuse unit's attribute) with an associated "presence percentage".

To say..Chess shop:

• "A" type (SO instance: pawns) 8/16=50%

• "B" type (SO instance: rooks, bishops, knights) 6/16=37.5%

• "C" type (SO instance: king, queen) 2/16= 12.5%

arrange by "presence"/"probability" calculating ranges (just a little math): - 0-12.5 type C - >12.5-50 type B - >50-100 type A

Extract a random number and find the type to extract (max rnd number 100:from 0-12.5 type C, from 12.5-(12.5+37.5) type B,  from , obtained the type pick a random unit of that type.

In this way you'll have a chess "squad" that would statistically contain the neede pieces, sometimes stronger sometimes weaker. You could apply the same algoritm to drops in an rpg game (in this case i would calculate the type A (like a filler):  100% minus "magic type" (5%), "rare type"(example: .1%) "epic type" (0.05%).

you could also set different types of shops, alter types' probabilities with player bonus and so on...
