Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Creating a pattern lock screen

Hello folks,

I am trying to make a pattern lock screen like the one you have on your phones using blueprints.

What I THINK I should be doing is:

  • Place some sprites on the scene as an actor blueprint.

  • on Event Clicked > each blueprint should be getting added to an actor array.

  • on Event Released > compare the array created here with the actual array it should be.

my problems with this are:

  1. I don't know where I should be creating the array and where I should be adding the actors to it. (In the Level blueprint, or in each actor's blueprint seperately?)

  2. When I create an actor blueprint for a sprite and I copy it multiple times into the level, I still have 1 blueprint. That means I'll be just adding 1 actor to the array?

The documentation on arrays doesnt really help..

I'm very new to blueprints and any help would be much appreciated.
