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"

Array of Execs

That's it... I kinda made an array of execs. But I guess I was not supposed to! :D
Here is a picture of it:

And me thinking about the possibilities:

It could be even in the feature request category, but I guess Delegates are filling the need of this.

Hi Crimson Hawk,

I believe there is a misunderstanding here. The make array you have is called a wildcard array. It is basically an empty variable, not an array of execution pins. You can, however, place multiple execution pin lines into a node with an execution pin input, you should only be limited to how many outputs an output execution pin has (should be 1). Additionally, you currently have no variable in your cast node object pin, so even were this to work your cast would fail as it is checking nothing.

Yes, it wouldn't run, that's for sure, and the Make Array doesn't have variable set yet, I just needed it when I accidentally created this monster. But I could make the Get node to work with execution pins, as you can see, it has write triangle input and output, that could be connected to the exec input of the Cast node. (I wanted it to connect to the Object, but it automatically connected at the exec pin instead and changed his pin types accordingly)

That would not work. As you can see here:

The get array node does not have an execution pin unless it has been modified via c++. The add array node does, but a wildcard array cannot be plugged into the execution pin value. This would be illogical as a wildcard array is just an array of non-specific variables that contain no value. Do you have a modified engine? It may be that a change made within a custom source engine has caused this error to occur, otherwise it should give you the warning seen in the second image.

Yes, I know it doesn't work like that, and yes, I know how do arrays work, and no, I don't have a modified version of the engine. But as you can see, I could still create that Get node, so there must be a tiny bug in the engine. Array of execs in, one exec out. Those pins were connected automatically, when I was putting down these three node.

Do you have steps I can take to reproduce the error you are experiencing in a clean, blank project with no additional content?

avatar image CrimsonHawk Oct 18 '16 at 04:12 PM

Yes, it's quite easy. Just RightClick anywhere, put down a Get node. Pull out its right pin (Drag'n'Drop?) and in the upcoming window choose any function that has execution pin.
