Condition To Find Empty Array Slot?

In Blueprint: I am trying to find a way to use a bool to check to see if array is slot is empty. The array type is actor.
If the slot is empty, I would then use “Draw Text” to Empty.

Any help using Blueprint to do this, would be greatly appreciated. Thanks

Not sure what returns on a “Null” for things other than number variables.

Find a slot that you know is empty. Get it, and print. For instance, if it prints 0 like Int, Float, Byte variables would, then you use one of the Equal nodes and if = 0, then it does the Draw Text.

I think other variable types should return a string if not 0. Then you can just do Equal(String) and leave one of the inputs blank.

Try the “IsValid” node. If you still a bool for use elsewhere, set it after the test.
