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"

translate direction and speed to values for moveright and moveforward

Hi All,

I have a animation blueprint I'd like to share between the player character and AI driven bots. The animation blueprint currently is driven off of values obtained from MoveRight and MoveForward axis values. However for AI driven bots, these are obviously not getting triggered since there is no keyboard/gamepad controls controlling AI bots. Question, is there a way to translate "direction" and "speed" in the event graph into values for moveright and moveforward?

 InputComponent->BindAxis("MoveForward", this, &ACharacter::MoveForward);
 InputComponent->BindAxis("MoveRight", this, &ACharacter::MoveRight);
 InputComponent->BindAxis("Turn", this, &ACharacter::AddControllerYawInput);
 InputComponent->BindAxis("LookUp", this, &ACharacter::AddControllerPitchInput);


in the event graph for anim blueprint, I can get access to TryGetPawnOwner->CalculateDirection and TryGetPawnOwner->GetVelocity->VectorLength->Speed

Is there a way to get the direction and speed and translate it to values for "moveforward" and "moveright"?

Thanks

sounds like you need to convert from Polar to Cartesian coordinates, with a bit of trigonometry.

 MoveForward = Speed * cos( Direction )
   MoveRight = Speed * sin( Direction )
