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"

Set by reference macro plugged to a select node will cause cook failure

If you connect a macro that sets a variable by reference to a select node it will work in the editor build. When trying to cook the game, it will cause an error and fail the cook.

It would be great if this could be fully supported. Unless there is another way to do the same thing?

This is a small example, but it would be really handy to be able to use this with select nodes that have a greater number of input options.

Hello ILP,

I was unable to reproduce this issue on our end. I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

  1. Can you reproduce this issue in clean project?

  2. If so, could you provide a detailed list of steps to reproduce this issue on our end?

  3. Could you provide screen shots of any other blueprints/settings that may be involved?

I just tried a clean FPS project in 4.15 and it also fails to cook. You don't even need the actor in the level to get a failure. It seems just having a select node hooked up to a macro that changes variables by reference will break it. Here is a simple test case you can setup. Also attached is the log from the failed cook.

Edit: Removing the connection and compiling the blueprint will cause the cook to succeed in my clean test project. alt textlink text
