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 detect stairs

My game has an unusual physics world, so that for some reason I have to implement movement of my character myself. I have no problem implement basic movement, jumping and climbing. But I dont know how to detect something like a stair or some small object on the ground which the character is supposed to move over. I used AddActorWorldOffset to implement all the motion and check Sweep Hit Impact Normal to see if the mesh can be climbed. I dont see how to check if the Hitting surface is "low" enough to be stepped over. I disabled all physics, since otherwise things go pretty wired.

I guess you could cast a second ray going upwards, starting from the impact location of the first hit, and check the distance between second impact and initial impact.alt text

Other possible solution I see would be to tag your stairs objects as 'stairs' and cast your hit result as stairs object and check if it's true or not?

Hope it helped
