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 smoothly scale an actor in blueprint?

I'm trying to animate a 3d scene but I'm not able to set a smooth scaling effect across my objects. I'm aware of Move Component To which gives easy access to ease in/out and time taken to complete the animation for movement, but I can't find anything similar for scaling. Is there some alternative way to do this in blueprints?

This is what my animation currently looks like : http://gfycat.com/WealthyAllGrackle

If I could grow it out of the blueprint by smoothly animating the scale value of the objects, that would look great.

You could try using a timeline to drive the output parameter that is used for scale. Timelines update as tick as the timeline plays and can call events using the timeline values. Just draw a nice S shaped curve by converting the start/end points to curves and dragging the tangents around.

Timeline Documentation

You could also define your curve mathematically if you want, but timelines are much simpler to set up.

Thanks for replying Ryan. I had tried this earlier, but I couldn't figure out how or what to plug in where to get it to scale my object. Could you show me how I should set up my blueprint using timelines so that I can scale the object.

EDIT: ALMOST GOT IT. I experimented a bit and almost solved it, but I just can't figure out how to plug my data into the set actor scale action. Its like I'm missing a step that will combine the data so that set actor can use it.

EDIT : GOT IT. I had to use a vector track (was using float earlier). Plugged it into Set Actor Scale and it works perfect. Thanks again Ryan.
