You probably will need to create lots of clones too (best have a pool for each type). j3o file) in prestep.Р”Р„nd then you will need to deserialize (load from.

Trying to convert your Libgdx assets, then code game with jME.

Trying to build all new from scratch in jME (assets and game).

There are generally two pathes that you could take: fnt) file - and a large texture, that contains many smaller texture regions (in computer sience this is called РІР‚Сљtexture atlasРІР‚Сњ for 3d and РІР‚Сљsprite sheetРІР‚Сњ for 2d)РІР‚В¦ In the end - itРІР‚в„ўs just some small text data written in a. atlas files contain (names for regions, image format and even sub-channel format). fnt2 files will also contain information that. atlas files, but comes from a different corner. fnt files is very similar in concept - it is very similar to. You could write some custom code that reads. atlas files (and does not seem to have a concept for that either). Okay РІР‚В¦ so you see how important context and exact words areРІР‚В¦ Saw your text popping up at the same time. РІР‚СљSprite sheetРІР‚Сњ is the thing that in jME is called РІР‚СљTexture atlasРІР‚Сњ. РІР‚СљTexture atlasРІР‚Сњ (.atlas) is the libgdx term for the image_name_meta.txt that I sketchedРІР‚В¦ ThanksР”Р„h РІР‚В¦ Aha РІР‚В¦ I just watched this РІР‚В¦ Creating and Using Spritesheets in LibGDX - YouTube

This seems straight forward, does JMonkey has built-in functions such as loadBufferedImage() and bufferedImageToTexture()?Р”В¬an TextureAtlas be used to avoid all these mess? If so, can you give me a hint how to do it. I am thinking the second possibilities is to load the sprite image as one BufferedImage and draw the individual tiles on smaller BufferedImage and convert them to Texture. Do I have to cut the tiles and save them as individual images on my hard drive before loading them back to JMonkey as different textures? It is much easier for me to edit the sprites if they are all on one single sheet thus I donРІР‚в„ўt want to cut them up. I will add 3D feature after I port the game. I am less familiar with JMonkey it seems JMonkeyРІР‚в„ўs TextureAtlas is a different concept, am I right? I decided to convert my games to JMonkey. Unfortunately the scene graph support of Libgdx is weak. For nice tile maps, it is straight forward to manually create the РІР‚ВatlasРІР‚в„ў by using a notepad (that is actually how I create). In Libgdx, I can have a РІР‚Вsprite sheetРІР‚в„ў and use TextureRegion to designate the different tiles as separate textures. I actually tried to use TextureAtlas before I post my question. Not sure what you are trying to do - so I just said everything that came to my mind regarding that thanks for the reply. Another possi might be to use a РІР‚Сљ3D textureРІР‚Сњ (sampler3d) which is quite an old feature (I think) and then you would simply put your tiles as slices in the w-coordinate (u and v are sampler2d, w is the third axis).But itРІР‚в„ўs definitely going to solve the problems of a texture atlas.I donРІР‚в„ўt know what kinds of graphics cards support that feature (driver version, GL version).I donРІР‚в„ўt know if jME 3.0 or 3.1 support that feature (but I would like to know).In more recent versions of OpenGL you have РІР‚Сљtexture arraysРІР‚Сњ or РІР‚Сљarray texturesРІР‚Сњ.Texture atlases are often used for game characters and objects and to avoid the problems above, special care must be taken - example: configure a margin of 8 or 16 pixels when you bake your textures in Blender - which then minimizes РІР‚Сљcolor bleedingРІР‚Сњ (parts in such an atlas are not power two tiles but random sized n-gons) and it also fixes РІР‚Сљwrap around artifactsРІР‚Сњ (when using a special tile-based shader).Note: this is not a problem if you use the tiles on e.g. I observed this behavior when writing a special shader with tiled textures. This comes from having different pixels next to your quad. when trying to use a large polygon with one of your tiles repeating multiple times, then strange lines will appear between the repetitions. You will get problems with РІР‚Сљwrap aroundРІР‚Сњ - i.e.

Which will then work for the first 6 mipmap levels and break at the 7th mipmap level, because the tiles РІР‚СљbleedРІР‚Сњ into each other (РІР‚Сљcolor bleedingРІР‚Сњ is actually the term for that phenomenon). If you use texture min/mag filters with mipmaps, your tiles must be a power of two size - e.g.
