We definitely know how to use lists now. We also know how to declare a new list and add, remove, and retrieve elements. Moreover, you have learned that the data stored in List<T>
must be of the same type across all elements. Let's throw a little curveball.
ArrayList
is basically List<T>
without a specified type of data. This means that we can store whatever objects we want. Storing elements of different types is also possible. ArrayList
is very flexible.
Take a look at the following example to understand what ArrayList
can look like:
You have probably noticed that ArrayList
also supports all common operations, such as .Add()
. Lines 12
to 15
add different elements into the array. The first two are of the integer
type, the third is a string
type, and the last one is a GameObject
. All mixed types of elements in one variable!
When using ArrayList
, you might need to check what type of element is under a specific index to know how to treat it in code. Unity provides a very useful...
