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"

As I already have blueprint movement in my AI blueprint, can I still use a behavior tree ? I watched some tutorials on how to use BT, but they all seem to create new movement system instead of using the one already created in the blueprint. :/

Totally forgot about way simpler way, check if OrientRotationToMovement is ticked, if not tick it and control the rotation rate with the rotation rate variable.

Yeah. You must be right, but actually I have no idea how to use a BT. This is quite new for me and the BT isn't that simply to use since it requests an AI controler :/ Do you have any idea how I could make this very simply ?

this variable is a member of the character movement component, open your character bp, select the movement component and search for this variable in the defaults menu.

Are you talking about this ? alt text

I'm trying to play with it, but it does not seem to do anything :(

Figured it out. Here is a copy/paste from the the official tutorial :

To get your AI character to rotate based on movement enter the BasicAICharacter>Defaults tab. Find Use Controller Rotation Yaw and set this to false. Open the Components tab and find the Character Movement. Find Orient Rotation to Movement and set it to true.
