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"

So you aren't getting errors anymore? For the trampoline problem, after the SetSimulatePhysics, SetLinearDamping and play with the value.

Hopefully this helps and if it does, I'm begging for some karma cause I want a badge ty.. ;)

Ok, so the problem is that your PrimitiveComponent isn't being initialized correctly and is set to none, when you're trying to add force to it. You seem to do it properly, tho you must connect the event initialize to the Set primitive component. You forgot that? :P

Hopefully it works after you connect them, cheers! :)

I think I'm not so good in that and my english is really not the best... Is it that what you mean? Because now its like a trampoline and after I played with the Lerp A (500000 & 50000 & 5000 & 2000 & 1500 & 500 & 200) and TraceLenght (150 & 100 & 50 & 10) there is still no serious effect.

hello. first you have to plug your "set" to on begin play event for exemple, here on your graph, it s not getting initialized cause it 's not linked anywhere .
