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"

Hey lobaanicht-

You can set an OnClicked event for the button that, when pressed, calls the SpawnAcotrFromClass node to spawn an actor from the appropriate class.

hi Doug, thanks for your answer! unreal engine is new for me. can you explain your answer a little more? when i use spawn actor from class, no static mesh appear. there must also be a function to set the location of the object.

When using Spawn Actor from class it will prompt you to choose which class to spawn an actor of. So the simplest solution would be to create an actor blueprint and give it a static mesh component set to the static mesh you want to spawn. Then in the SpawnActor node you would set the Class field to the blueprint. For the location you can pull off of the Spawn Transform pin of the spawn node and choose Make Transform. This will allow you to set the location, rotation, and scale of the actor when it is spawned.
