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"

How to interact with actor when it is in hidden level

I am trying to create material and level changing option. I have created theme packages which player can change in game and also able to change different levels. But whenever I change theme package it changes only in the visible levels not in hidde levels. But i want the same material applied in all levels either they are visible or not. I am stuck here. Please guide me how can i solve this.

it depends on your actual design how did u do it inside the blueprint.

I would suggest the following.

  • Store all actors of all levels in an array .

  • On each item, change the material based on user selection.

  • For better optimization , store the material itself based on user selection, once the level is load apply this material to all actor inside the level .
