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"

When I apply lit material to sprite, it becomes completely black

It goes for all materials except translucent one, but I can't use it. I'm trying to light up tilemap level with some point lights but all sprites I add become black

I assume that the flame is a sprite set to unlit. The part that is not being lit (let's call it the flame holder) is set to lit and it's a sprite aswell?

avatar image MadElectron Jan 24 '18 at 12:14 PM

Yes. Fire flipbook is unlit and tilemap behind it is lit

avatar image xlar8or Jan 24 '18 at 12:20 PM

The character and the walls are set to lit or unlit?

avatar image MadElectron Jan 24 '18 at 12:41 PM

Character is lit. Tilemap is also lit, idk what do you mean by saying walls. I don't have anything except tilemap, torch and character in level.

Just so we are talking about the same thing:

Your issue is that the holder is black or did i understand it wrong?

Problem that holder is black was before I rebuild lighting :D . Now every sprite with lit material is black

Ah ok, you are using static lighting then? Have you tried dynamic?
