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"

Are you attempting to be able to show and hide the Crosshairs as the player aims in and out of his weapon?

If so you need to rethink your logic. Event BeginPlay is only called once when play begins on the level. So in essence it takes a snapshot of your AimButtonDown boolean variable at that particular frame. It is not capable of detecting when that variable changes.

If you manually change that variables value on your Player, you should see how it affects the drawing of the crosshairs.

You need to change your logic such that, when the player uses an input event (Right mouse button for example) to aim down their sights, this is where it would be more appropriate to decide to show or hide the crosshairs.
