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"

Some code only works when the BP is open in a seprate window.


I'm experiencing a bug in 4.15 that doesn't properly use my code inside my character BP correctly unless i have the BP window open, not just in a tab in the editor but a separate window. alt text

What this does is that: It executes upon pressing jumping button if character has a jetpack it does this bit. When the jumping button is release character stops using the jetpack and the loops stops/breaks. It all executes but the character doesn't fly unless i have this character BP dragged out of the tabs on the editor. See pic for example of what i mean with dragged out.alt text

So if the BP isn't open or in the tabs on in the editor that character doesn't "fly", it tries seemingly but it doesn't get enough force. All i'm doing is just dragging the BP from tabs so it ends up in a open window and it works again. I can do this while simulating.

Product Version: UE 4.15

Hello Blackrock,

I was not able to reproduce this issue on our end, I have a couple questions that will help me narrow down your issue.

  1. Can you reproduce this error in a new project?

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

  3. would you be willing to provide a screenshot of your variable values and the rest of your jetpack event, so I can better recreate your issue environment?

Thanks for the quick response! I don't seem to manage to recreate it in a new project.

Here is the whole functions, alot of it is irrelevant towards the jetpack.alt text

Character movement component mass is 45 000. Jetpack speed: 600 Jetpack Z force: 170000000.0 (Yes that is the correct number :) )

Been bug testing this for awhile now and started just printing strings of my character movement z velocity.

When the character bp is closed or in tabs it goes from 0 to negative (-)45. When having my character bp in a separate window it goes from 0 to upwards of 1700. Sometimes it starts off at -45. There is something funky with the character velocity.

I got the jetpack to work without being in a separate window with different values by unhooking the branch at the end from the branch at the beginning. Let me know if this helps with your issue!
