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"

Navigation not working as expected.

Hello there! So, main problem for me, the navigation can't handle big vertical levels. I am building game with procedural generation, and levels is growing downwards. There is no chance to move location with static character at zero.

So, here what i have tried, and what i get:

  • I maded navigation volume smaller at X and Y(smthng like 25x25 scale) and Z is 1000 and move to some -Z to make sure that it starts from top and goes down, where level will be generated. In this case navigation stops generating. Tweaking navmesh settings gives nothing. Only collapsing Z scale to 250-300 or smaller makes navmesh generation work again.

  • Then i have tried to use navigation invokers. Goes through few tutorials, done everything, and invokers is not working. Navigation is building like there is no invokers at all.

  • Also, tried to make small nav volume and move it every time to NPC. This seems working, but, i have some amount of NPCs and this will cause same quantity of nav volumes, so this looks not right, and this is not what i have expected from simple navigation system.

And last one, navigation builds each time differently with same settings. Can't figure out why.
