How to Get Data FROM the Object Implementing an Interface - BPI with Interactive Door Example

This is a quick tutorial on how to get data FROM the object implementing the interface. In this example, we get the size of the door to determine if our character has enough strength to open the door.

Thanks, very helpful. 0:44, 4:35 And you explained keywords for when to use Output vs Input. But the title is bad for how useful this vid is. Suggestion to add [to the title or search string that YT uses] "BPI how to pass variable" so that people who know what [keywords BPI] theyre searching for can find this.

KZbin figures out over time how useful videos are. Not too worried about it.

@@NumenBrothers Im speaking of users manually searching for "BPI" and how to pass a "variable" (which is a more precise word that theyll think of instead of "data"). Ive spoken with 6 people who want this precise info but they wont find it if you dont have the words in your title/YT search tags. ("Interface" isnt as precise, I guessed that it means BPI. But I only see this vid because I am subbed; Searchers would not find it this way - I tell them what keywords to search for.)
