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"

You can simply open the Gate when you press the key, and close it upon release.

Or set a bool wariable to True/False, and do what you need while it is True.

What is the action you want to execute after the ley is held down for some time? You can use Tick, Gate and a float variable — add Delta seconds to the float on each tick and check if it's more than, say, 3 seconds; and when the key is released — set float to 0;

Or upon presing the key start a Timeline with a curve that goes from 0 to 1 in 3 seconds, and check if the value is 1. The same curve may be used to drive some animation like a progress bar.

Hi, you can try one of those solutions:

The first one (F key) invoke your methods ONLY at button release.

The second one (E key) invoke your hold method if the time has passed, the normal method at release (if the hold didn't get invoked).

Hi Iohoilpotere, thank for support, but this solution will work if you press key or use input. I need sumulite hold without any keybord, in my functional tests I save all user input in array and send it to server, but when I execute press button event I need sae server hold button, I can not use epic event.

I work only with "code" without any input (keyboard or gamepad). In other words, I want call "any key" event via blueprint when game run. Sorry for my english.
