create a new texture manager api #26

Open joshmarinacci opened 5 years ago

joshmarinacci commented 5 years ago

currently it's not clear how textures are loaded and how they are mapped onto blocks. we need a new api.

joshmarinacci commented 5 years ago

this new api should let you

specify the full url to an image, possibly even remote
indicate if a texture is animated and how many frames
for block types with multiple sides that are different (ex. grass on top and grass mixed w/ dirt for the sides), specify each of those sides
indicate if the image has transparent parts (cut-outs, not true alpha)

Hi Josh, I was looking at your code and noticed this issue. Would it be beneficial for speed if textures are grouped in sprite sheets and injected in the code(build) via base64 encoding? If you then serve your code via gzipped file I guess the download would be faster.

Yep. It definitely should support loading tile textures from a spritesheet. I don't know if base64 encoding would help, though. PNG is pretty compact already.
