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"

How to add small rotation and translation each frame when using RootMotion?

How to add small rotation and translation each frame when using RootMotion? I am using successfully the root motion system and I want now to implement a system of correction to adjust to the desire vector of the AI/Joystick input. What is the best way to add rotation and translation each frame in addition to the RootMotion extraction?

RootMotionParams.Accumulate(FTransform) seems to work. I call this function in the Tick component function. Is it the right place and right approach? Thanks.

it works perfectly but i had to put a hack to apply the correction every other frame to reset the accumulation. Otherwise i get an oscillation problem. Any better solution?

static bool Apply = false; Apply = !Apply; if (Apply) { CharacterMovementComponent->RootMotionParams.Accumulate(DeltaRegistration); }
