How to code triggers to react differently for different character options?

Getting Started

I am trying to code different triggers so that some triggers will only affect certain characters. For example, the water character will evaporate(die) in fire/lava, and the fire character will extinguish(die) in water.

I was planning on making different triggers for each element so that they affect other characters differently. Although I have a plan, coding the triggers to react differently to each character is new to me. While I am familiar with C++ and Java, this is my first project using C# and coding in Unity.

My coding plan is to set a public variable to a different char/int value per water/fire character, and then have it that if the public variable == [insert appropriate value] then the character will die. The problem is I do not know how to format or code that, as I’ve just copied the sample code for triggers from Unity’s Sample 2D platformer.

Could someone give me some tips/guides/sample code/etc?

Well, I am new to this as well, but immediately Interfaces come to mind.

A better place to start on your general scripting adventure is the Getting Started forum. There’s also plenty of tutorials to go through on the Unity Learn site.

Sounds quite advanced what you’re doing, are you an experienced Unity developer?

So yeah just have a property tied to the character script like:

public string elementType;

in the inspector, input what type they are ‘Water’, ‘Fire’, ‘Earth’ etc.

Then in the DeathZone script, just write conditional statements in the OnEnterTrigger2D method.

if (player.elementType == 'Fire') {
// Do this
}

if (player.elementType == 'Water') {
// Do this
}

Might also be a good idea to fine tune your collission Matrix, if you only want player objects to interact with ‘DeathZones’.

No, I’m only experienced with C++ and Java from classes that I am/was taking.

Oh, that was way simpler than I was thinking! I thought that I would have to create separate classes within that file!

Gotcha, and l am actually watching some of those tutorials rn! Although, it might be a while before I reach to where I need and this is for a college project, so I will post this in the Getting Started forum if I still need help! Thanks!
