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 change collision responses in blueprints to achieve this behavior.

yup collision response is the way to go. you could even make a new collision channel that everything in the world is set to ignore except the ground then set your character to use that channel while the button is pressed.

But in which blueprint do I do that? and how?

  1. In project settings add a new collision channel: alt text

  2. Assign this channel to your walls: alt text

  3. In your character blueprint, grab your mesh and set collision response for your channel: alt text

P.S. I highly recommend to visit official tutorials. They are super helpfull. https://docs.unrealengine.com/en-us/GettingStarted

Don't forget to mark this as answered if it solves your issue.
