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"

The node displayed in the documentation is a latent node (as indicated by the white clock icon in the corner of the node). Latent nodes are used for asynchronous operations, or operations that take time to complete and then call back to the node. Because they have callbacks, a latent node can't be placed inside functions, but must instead be placed inside an Event Graph. You can place a latent node inside a Macro, but then the Macro becomes latent; so then the latent Macro must be called only within an Event Graph.

The documentation makes reference to the IAP nodes having latent and non-latent versions, but it isn't called out specifically (as it probably should be):

The Make an In-App Purchase node is latent, so any gameplay behavior you want to have rely on whether the purchase succeeds or fails should use those two execution pins. They will only execute after a response has come back from the online service. The node also returns the completion status of the purchase (such as Success, Failed, Restored) and the detailed In App Purchase Information struct.

There is a non-latent version of this function (the Blueprint node will display without the clock). The exit execution pin here does not wait for a response from the online service, and you will generally want to use the latent version.
