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"

Variable from last frame

Hey there! I've got a little lack of experience problem here. I have a variable that I create in script(blueprints). What I need is to find out what was this variable last frame. Is it possible to somehow store it and access it next time, than again replace with new variable? Thanks!:)

Product Version: UE 4.12

This is a very simple example showing how to use a (float) variable which stores a value and uses is in the next frame.

The functions Do Something and Compute Variable (sry for the spelling error in the screenshot) are just dummy functions I created to show you the places where you have to put your data in the variable and where you can use it in the next frame.

I hope this helps you.

Thanks! This kind of works. It just took me time until I found the variables tab on the left:D I am totally, totally new to UE4, but I imediately went into making code with just a few tutorials. Should have taken a bit more to spare you time writing this answer. Thanks anyways:)

I believe what you're looking for is the Tick event, which is an event that is called every frame.
