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 can I generate a map/minmap using the navmesh?


I'm interested in making a Diablo/Torchlight style map/minimap. I'm not sure how to approach it. One way I thought about it is using the SceneCaptureComponent2D use a 2D hand drawn texture of the level, but that doesn't work for me because my dungeon is generated randomly with premade tiles and I don't want to draw a map for every tile, and if I decide to add new tiles I have to draw again. Another way I was thinking about was to make another camera with an outline post-processing effect on it and use that, but it still seems like a cheap solution and I don't know if its costly. I came across a couple of posts here on using navmesh with a texture to achieve the desired effect but I'm not sure if it is possible and how to even achieve it since they had no answers.

Thanks in advance!
