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"

Remove cut off from mesh slicing

I have procedural mesh slicing set up, but I need a reliable way to remove the cut off segments after a delay. Any help would be appreciated.

Hey,

I got something going in a test project of mine that may help you out. When I make a slice, I add it and a destroy time for it into arrays. The first time I make a slice, I set a timer to kill slices after a given amount of time. If I make more slices after the timer has been started it's OK, we'll handle them in the timer's callback function.

alt text

When that timer expires, it calls a KillSlices function in my actor. It loops through the slice kill times and compares them to the current time.

alt text

Any kill times that are not in the future have their slices destroyed and their entries removed from the arrays. Then, if we have slices that still need to be killed in the near future, we reset our timer to call KillSlices again when their time is up. When we've removed all of our slices from our arrays inside of KillSlices, we set a flag so the next time we add a new slice we know to start the kill timer back up again.

alt text

There are probably optimizations to be had and some more safety you could build in, but I can cut slices to my hearts content, and they get killed roughly X seconds after being spawned.

Looks like that should work. Thanks!
