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"

for me i use a blank parent actor with a structure of all the details including class and then write all the code in the main and pass it to the children class and it works perfectly if you want details let me know

Does the output log show any warnings or errors related to spawning? Is the return value of the SpawnActor node empty? If not then are the location and scale values what you'd expect?

That way I got this back, I wanted me to return the guns for the class. I must be doing it wrong. Sorry for my English.

It is good practice to store the spawned actor reference instantly in a variable so you don't lose track of it. Something like this:
alt text It greatly helps readability and debugging.

In any case the "Accessed none" messages indicate that things did not go perfectly at all. :) It could be that the spawn location is inside colliding geometry. Using a shape trace (https://docs.unrealengine.com/en-US/Engine/Physics/Tracing/Overview) you can check that the location you intend to spawn the actor has room for it. Or for a quick hack you can just set the Collision Handling Override param to "Always spawn, ignore collisions" and see if that helps.
