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"

Blueprint - Passing on Setter Variable

Hi Guys,

I had a thought I will share about improving the flow of blueprints so I thought I would put this out there and see what people had to say about it.

alt text Okay so Ive seen in alot of cases where people want to set then immediately want to use a getter for that same variable. This lead me to thinking why not have the option to pass along that variable, using a var in a branch/if typically you want the option to pass it into the branch so its just a more natural flow.

alt text The above example is passing along TempAirSpeed to AirSpeed, so we can still access and modify the variable separately with a getter but only when we really need a new getter.

I dont see any major optimization issues as the variable is readily available anyway, this doesnt need to be a get and set for something like AirSpeed, its pretty universal. As in this example:


OverlappingActor reference and PoweredUp boolean can be passed along rather than breaking the flow of the expression.

Heres some typical blueprint usage, a dodging function. You can see most of the flow gets broken at the setters, that I can pass along these from the setter in alot of cases and it matches the execution flow.

Beware, I am a total noob and can only manage to utilize blueprint from trial and error and looking at other completed blueprints.

Heres my problem. I have tried to duplicate this out of pure nostalgia from dodging in UT, but the nodes after the "Event Do Dodge" confuse me. How do I even create the input "DoubleTap Left" and "DoubleTap Right" to connect to "Dodge Dir"? How could they even correspond to my left movement key and my right movement key?
