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"

Bind the percentage of your progress bar to a float variable. Lerp this float variable with a timeline in your widget blueprint. Now it's "animated".

Hello cageman,

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 a 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 blueprints that may be involved with this issue?

I tried to do it again..

  1. yes i can repro, it seems you have to activate the curve editor for it, i can't add any keys there! Only when i de-activate the curve editor i can add points, which makes it a linear transition, right?

  2. Create a new widget, add a progress bar to the canvas. Add an animation. add a keyframe for percentage 0.0 and a keyframe for 1.0. The keys are now added without the curve editor, so that part works. Now select the curve editor.. where are all my keys?

  3. no blueprints involved, just umg.
