Question how do i get the index of an array?

i want to make a system that identifies the array index of the object that the player touched, i have searched a lot for this and the closest thing i managed to finf was IndexOf or something of the System.Array.IndexOf, but the code doesnt allow me to use that.

is there a way to do this? whats the System. i need to use? or do i just use a list instead of an array?

 

well

Code (CSharp):

1. for(int i = 0; i< array.length;i++){
2. if(array[i]==objectTouched){index = i;break;}
3. }

its not clean, ideally you should structure your data so that the object contains info on its own index to avoid iterating through the whole array

 

In a similar vein as karderos, why dont use simply use colliders to detect when a player touches an object? Thats what they are for. I guess, why do you need the index of the array when you can probably just create a function that says if i touch this object (or any of the multiple objects) then tell the ObjectController to do _____ ?

 

The others implied so already, but why do you think you need this index? Depending on your architecture this may be a valid usecase, but it sounds more like a XY Problem. If you tell us the actual usecase we may be able to offer more specific solutions.

 

IndexOf

works, you probably didn't use it right. It takes some experience with normal computer programming in order to read the description and understand what it's telling you to do.

A different Unity trick I use is when the objects that can be touched also have scripts on them. Just make an extra variable and write the index on each object's script. You don't need that, since IndexOf can find it anyway, but it makes things easier and doesn't waste much space.

 

well, i already found a solution with lists but thanks anyway!
