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"

Getting & Setting Variable from different Class Blueprints

Hello everyone!

I would like to know if it is possible to get & set a float variable in a blueprint (CurrentHP) before "knowing" in which blueprint i want to get/set it?

What i a trying to do is the following: I am building a basic hack n slash game where my player swings a weapon and on each weapon swing i check if the weapon hitbox collides with a "monster" hitbox. I made the whole thing work with one specific monster. But now i wanna use different types of monsters (and blueprint classes). Therefor i did create a parent "monster" class and will have several different monster childs from that parent. In my Player Character Blueprint i check if the weapon collission hit a child of the monster class and if so loop the hit monsters to get damage. The CurrentHP float is saved in the different child classes. Now i would like to know how to set the CurrentHP float variable?

Thanks in advance! I hope i did manage to describe my problem in a understandable way...

Hey all!

I managed to solve the problem after talking about it with a buddy. I went at it the wrong way around and i am a newb to parent classes (well, to programming and UE4 in general ;) ).

I did not know that all childs inherit the variables from the parent class. So, i set up a "CurrentHP" float in the parent class and also made a custom event there ("GetDamage") which gets triggered in the PlayerCharacter Blueprint. See enclosed Screenshots.

Maybe this solution can help someone else with similar problems. If there is a better way to solve the problem, please let me know!
