Okay, I believe you can't wait, go and try it

Some broken thoughts:

在很多教程中，IEntity和IEntityDefinition两者的差别并未完全指出，借用youyi大佬的话，其实IEntity是一堆生物，IEntityDefinition是一只生物，就是这样......大概

When we get a collection of "all entities in the world", how can we judge that "the entity I want" is not inside?

cycle.

The answer is the cycle for I in [1,2,3], which will "substitute" i in the collection of I, in the above example, this meansAt this time, judge at this time, if (if) "inspire" to find equal (==), then put it in a new collection. In this way, when the FOR loop is rounded, all eligible objects will be selected.Putting into a new collection means how many target entities in the world have.

For the above if (! Isnull (mobentityDefinition.Definition) && MobentityDefinition.Definition.id == .id), first isnull () is used to determine whether the things in the brackets are in the brackets For empty, if it is emptyReturning True, returning True indicates that if the IF continues to judge the next step, and the next step is to be hollow == .id, obviously unreasonable, so the number of empty pointers (NullPointerexception);

Therefore, you should return to FALSE, so use it! Take the opposite, that is,! Isnull (), it means that if it is empty, it returns false;

&& means harmony;

The difference between equal to the number is: = indicate the assignment, == represents matching;

Finally, I would like to thank Youyi for the help and the help of many groups of friends (the ID is too outrageous, it is strange to fight), and thank you for the enlightenment of the big brother of station B (he learned a lot from his small tutorial for changingCome (laughs))
