How to iterate over Serialized List?
Currently what I am doing this but it doesnt work, it prints the correct size of the serialized array but not the content, how can I do it?
Debug.Log("Size: " + l.serializedProperty.GetArrayElementAtIndex(l.index).FindPropertyRelative("down").arraySize);
for (int i = 0; i < l.serializedProperty.GetArrayElementAtIndex(l.index).FindPropertyRelative("down").arraySize; i++) {
Debug.Log(l.serializedProperty.GetArrayElementAtIndex(l.index).FindPropertyRelative("down").GetArrayElementAtIndex(i));
}
It depends on what's inside "down". GetArrayElementAtIndex just returns another SerializedProperty, so you need to access what's inside that SerializedProperty to print it. Suppose down is a a List of GameObjects: public List<GameObject> down;, you could do it like this:
SerializedProperty downProperty = l.serializedProperty.GetArrayElementAtIndex(l.index).FindPropertyRelative("down");
Debug.log(downProperty.arraySize);
for (int i = 0; i < downProperty.arraySize; i++;)
{
Debug.Log(downProperty.GetArrayElementAtIndex(i).objectReferenceValue);
}
You can find how to get the value of different types of properties in this doc page. All the members that have the word "value" in them serve to access different types of data. Although, if down is an array of custom structs or classes, you'll need to do a bit more than that.
It is actually a List<GameObject> , I am currently using objectReferance as GameObject is it the best practice?
@kayraucklnc Yeah, it's perfectly fine; that's what everyone does. I modified the answer's example to make down a list of GameObjects. Does it work for you?
EDIT: Well, it's not objectReference; it's objectReferenceValue.
Hi, Uhm. If it works for you, could you mark my answer as correct? If it doesn't, could you share some of the class being serialized? That would give me a better idea of what isn't working. Either way, I'd appreciate some feedback or resolution, as it helps other people finding this question in the future, and it helps me to measure the productiveness of my time.
It totally worked! Thank you, one more follow-up question, sometimes I cast with as GameObject but since it is actually a null value It gives me an error what's the best way to avoid this? Should I use try-catch?
