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"

I have tried to check if there are any bullets in my weapon blueprint, but every time it returns the variables I have in my weapon blueprint as empty.

I think it is related also to this error: alt text

The pointer variable "Equipted Weapon" is null when using it. That is forbidden! Use an "IsValid" node for all your pointers before actually using them. This is basic C (not even C++). If you don't understand what i'm talking about, watch this video of me:

Ok I understand now, but in the BP_Character I have set EquippedWeapon to be a reference to BP_Weapon_AK74. Doesn't that mean it's not null and is valid, because when I try to verify with IsValid it returns it is not valid :/ I can put my entire project in .rar and send it to you to check :/

You will get non valid on null too, as null is a soecific adress (zero) which points to unallocated memoery which is not valid. Which means most likely means one of object varables is not set
