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"

Hey cmjames,

It's likely your stairs don't have any collision on them. Did you create a static mesh from a bsp brush, or import a mesh without a collision volume? You can check to see if your mesh has collision by opening it in the Static Mesh editor and clicking the Collision button in the toobar. If you don't see any green lines appear on your mesh, it doesn't have collision. You can add some by going to the Collision menu in the Mesh editor and picking one of the options there. You'll probably want to choose auto-convex collision for something like stairs, but there are other options to play around with.

Hope that helps!
