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"

Not sure how to use Event Actor Begin Overlap

I'm having trouble with an overlap event, mostly because I just don't know how to feed it the actor I want it to collide with. I saw the image below while googling my problem, but can't seem to figure out what it is: can someone help me out really quick? Sorry for the basic question. alt text

That's an equal to object node, you plug that in to your other actor pin on your begin overlap node and the other pin will be a reference to the actor that you want the overlap to recognise. Then you link your equal object node to a branch then from that you can do what you like.

There's an image here in this documentation which shows this method if you scroll down a little bit: Events

Alternatively try using a cast node; from your other actor pin create a cast node by typing the name of the actor you want the overlap to pick up, you should get a node that says 'Cast to BP_thirdpersoncharacter' or whatever actor it is, then from that you can do any other functionality after.

That helped a lot, but now it's just not working. What I'm trying to do is get it where whenever a box reaches one of the two points it moves between, a door will raise. Right now, the door refuses to move. I set up a Begin Overlap node with the target point being the actor the box needs to overlap. alt text

Target points don't actually have any collision on them so they wouldn't get picked up by overlap events, you would need to use an object that can generate overlap events or try creating a custom actor with a box collision that could be picked up by overlap events. So when your box intersects that collision it should activate your door.

Oh, my bad. Thanks a ton.

I would recommend you adding a box collision in your viewport's blueprint and start overlaping events from it.alt text
