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"

UMG DragDrop crashes iOS

If you follow the tutorial here created by Nick Darnell from Epic: https://forums.unrealengine.com/showthread.php?49644-UMG-Drag-amp-Drop-capturing-mouse-events

And create a Drag and Drop widget it will work in the preview and mobile preview, but once you package it and try it on iOS it crashes once it gets to the 'Create DragDropOperation' node in the blueprint.

I have confirmed this in a new empty Project.

I read a post somewhere that was made in early November that this wasn't a tested area (mobile and drag and drop) but I thought i'd post this issue anyways.

I also thought about making my own Drag and Drop to get around this (the detect drag works, so I could still use that part), I would just create the drag widget add it to the canvas and update its position based on the mouse and if the mouse button was being held, but what would be the best way to know the widget you are hovering over in a Drag?

Gave up rolling my own drag drop. Will just wait until this can be fixed.
