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"

Rinterp Mesh Rotation on Button Press?

I understand how to rinterp a mesh's rotation but I'm having trouble with doing it on the press of a button

I have a flip flop which rotates the mesh 180 degrees vice versa

my problem is that once I press this button it doesn't account for the entirety of the rinterp I'm guessing, so it only rotates it a little bit each time

I need to be able to complete the rinterp to the desired rotation on each button press.

Thank you!

That's because you have to connect Rinterp to either Event Tick or a Timer, since the Set Rotation node must be called multiple times to reach the target rotation.

E.g., your actor's Z rotation is 45 degrees, and you want it to turn to 90 degrees, and you set Interp Speed to 3 in the Rinterp node. It means every time the Set Rotation node is called, your actor will turn by 3 degrees, so you have to call the Set Rotation node 15 times.

I'd suggest looking into other types of interpolation, like using a Timeline and Lerp/Ease function. It'll provide more control over your movement/rotation.
