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"

Variables in arrays

I'm currently figuring out switch mechanism for equipment, weapons etc, and I'm not sure how arrays work. My question is that if u store let's say "firstweaponmagazine" in array and then call it later when it already changed by reloading will it call the proper variable or just the value it had in the moment of storing it in the array? If it doesnt work this way is there a way to achieve this? Also is it possible to make array of arrays?

What you store in an array is a reference to a variable. Not a value. This means it will always be the current value no matter where you changed it.

This also means you have to check if it's valid at all as it could be destroyed by the time you try to get it from the array.

If you want to have the variable at a specific moment you will have to create a new variable for this.

And no. As of yet multidimensional arrays (an array of arrays) is not possible right now in blueprint.

I hope this helps.

Hey, So something like this will store pointers to the objects, this means each variable stored in them will be update, i.e. the latest version of the variable. TArray myArray;

And I don't see why this wouldn't work: TArray> myArrayOfArrarys;

Hope that helps.
