Hello there! I’ve created some stat variables for my character. But these stat’s boundaries or values can change when other stat’s changes too. For example: my current health cannot be higher than my max health, or when my luck gets increased my crit chance has to gets increased too etc. I can make them minimum values in details section, but don’t know what to do with the other problem. Thanks in advance! ![image](https://d3kjluh73b9h9o.cloudfront.net/original/4X/1/8/a/18af2db347846787b3575fd8ab9afb8e40015e7d.png) ---

Hello there! I totally understand what you’re going through. I had a similar issue in my project. For ensuring that `CurrentHealth` doesn’t exceed `MaxHealth`, you can handle this in Blueprints by creating a custom event that checks if `CurrentHealth` is greater than `MaxHealth`, and if it is, set `CurrentHealth` to `MaxHealth`. For linking `Luck` and `CritChance`, you can create a function to update `CritChance` based on `Luck` and call this function every time `Luck` changes. This way, when `Luck` increases, you can automatically adjust `CritChance` accordingly. This approach worked well for me, and I hope it helps you too! ---

Thanks a lot for the answer, and also I should make an event for the luck’s change, just like the health event, right? ---

I’ve done something like this, and I will call this event whenever a luck changing thing happens right? Game development is HARD ![Ekran görüntüsü 2024-06-05 150000](https://d3kjluh73b9h9o.cloudfront.net/original/4X/7/7/8/778a432155856693d89536f2dad4849ed4f95c6c.png) ---

Yeah spot on that should work, let me know if you run into any issues when testing it out ---

a fancy way is to use objects as attributes. the objects can then bind to when their ‘parent’ attribute changes. so Luck updates, calls an eventdispatcher, critchance is bound to that dispatcher and updates its ‘luckbonus’ this also lets each attribute have its own maxvalue and can clamp when edited. slightly simpler is to use a struct for each attribute ( value maxvalue additive bonus multiplication bonus ) ---

I used struct before but didn’t think of it that way, seems pretty logical, I will adjust some variables like that, Thanks a lot!! ---
