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"

Removing Destructible Mesh 'Chunks' from World

Hey there folks ,

I'm working on resource collection in my game and I would like to make use of destructible meshes. I've created a rock that breaks down into smaller chunks through the editor. I know that I am able to physically push individual chunks about using the impulse function (through bp atm) .

What I'd like to know is :

1 - Is there any way to get a reference a particular chunk in a destructible actor ( when casting a ray for instance). 2 - How would I go about removing only that chunk form the world instead of the entire destructible component or destructible mesh actor.

I've experimented with this before back when I was using UDK for development but had no luck then either. Any help or advice would be greatly appreciated.

Best Regards and Much Love MrNexy

Hi,

Is there any way to get a reference a particular chunk in a destructible actor ( when casting a ray for instance). 2 - How would I go about removing only that chunk form the world instead of the entire destructible component or destructible mesh actor.

1 - You can get reference to a particular chunk via a ray trace. When using the break hit result node pull off the pin for Hit Bone Name and plug that into Print String if you want to see the result. This was my test for that.

2 - You cannot remove specific chunks from the world. Something could probably be done with code to do this, but there is not option that I am aware of included with UE4 to be able to do this.

UE4's destruction is on par with what was capable in UDK. There are some features that are still being worked on though but nothing to this degree that I'm aware of. You would either want to implement something via C++ or look into using PhysXLabs (Standalone app, 3Ds Max/Maya Plugin) to test results.

Thank you!

Tim

Is it still not possible to remove specific chunks from the world? I was playing around with DMs today, and I couldn't figure out how to do it. Also, I could could not get the chunks to trigger an overlap event.
