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"

Why could my very simple 2D mobile game have such a low framerate?

Attached is a picture of my game. As you can see, it is very simple, and is only using the same texture/sprite over and over again.

All of the "tiles" have their tick events disabled until they are needed. On my computer, it is a 70 fps, but on my phone it is a 6 fps.

I previously had this game in only UI, but now its actual PaperSprites, but its still getting immense lag.

I'm looking at these other more complicated games that have shaders, materials, lighting builds, complex maps, static and dynamic meshes, and a bunch of other things with huge overheads, then I'm looking at my game and I'm baffled that mine has such low framerates and theirs don't.

What could possibly be the issue here? Any ideas?

I'm often looping through all of the tiles, and using a lot of delay nodes. Does that affect performance?

Don't put delays in tick, and if possible, don't tick at all, use events instead. Are you redrawing things more than needed?
