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"

Unset state after loosing trace

Hello, i am using "LineTraceByChannel" in a blueprint to check, if an object is hit. If hit, i set the emissive color to a new value. How can i change back that value to default, when loosing my trace on the object?

you store the value in a variable before you set the temporary emissive color and set it again when you loose the trace?

Or is the question "how can i trigger something when there is no trace anymore?

I think it's your second question:

After i set the emissive value (e.g. to "1") and the trace-function looses focus on the object, the object-emissive-value stays on "1". What i want is, that after loosing focus, the emissive-value should go back to "0".

It's like a little hover-effect on interactive objects. They should show the player which objects are interactable.
