In effect, he was looking for the essence of comedy. He wanted to know what exactly it was that made people laugh. To go about this, he went on an epic quest (of sorts) to find out what exactly was funny. So, he ended up quitting his job, destroying his marriage, and almost ruining his life to find out why he wasn't funny and to use that information to fix the problems and become a successful stand up. The problem was that he had an itch, and it wouldn't go away. Most people would quit at this point (I know I did, but that story is a wild tangent, so it can wait), and in fact Rodney did quit comedy for a while. No one liked his jokes, he was booed off stage, he was a failure.

You see, Rodney Dangerfield had always wanted to be a stand up comedian, but he suffered from a simple problem. In the meantime, let me tell you about Rodney Dangerfield. Right now it is just one game, but in the next couple of days we should have a few more up.

Vertices = (NewMapHeight * FullMapVPercent) + UVMapPos.Happy New Year! We have started porting our Android games over to itch.io so that they can be played on any device, so head on over to our page there and check out what we have to offer. Vertices = (NewMapWidth * FullMapUPercent) + UVMapPos.getU() //New U PreviousV = (vertices) ДЇullMapUPercent = previousU / FullMapWidth ДЇullMapVPercent = previousV / FullMapHeight Int TimesToLoop = ((vertices.length) /floatsPerVertex) ДЇloat FullMapHeight = UVMapPos.getTexture().getHeight() ДЇloat FullMapWidth = UVMapPos.getTexture().getWidth() ДЇloat NewMapWidth = UVMapPos.getRegionWidth() ДЇloat NewMapHeight = UVMapPos.getRegionHeight() Int numIndices = ObjectMesh.getNumIndices() Int numFloats = ObjectMesh.getNumVertices() * ObjectMesh.getVertexSize() / 4 public Mesh RebuildMeshUVtoTextureRegion(Mesh ObjectMesh, TextureRegion UVMapPos) Tested, and it works for me but please review as i'm not a java developer. I can't believe so few are people are running asking this question as it seems like something that others would want to do.ДЇrom the accepted solution I created a function that also does the math for the new UV position. Got it to work using the above explanation. SpriteBatch supports sprites defined with a TextureRegion and the AssetManager supports loading and finding a TextureAtlas as a first-class element. Part of the benefit of a texture atlas is that it should contain a lot of regions that can be rendered together, so you only need to bind one texture, and then render a lot of different textured meshes from that one bound texture. Note that this is much less efficient than it should be. Render the textured MeshДЇinally, when you render you need to bind the image, and enable texturing before rendering: region.getTexture().bind() Since the texture is large (say 512x512) and the specific region is a small subset of that (say 20x20 at 128x128), you'll actually end up giving your mesh texture coordinates that utilize just the 20x20 subset of the entire 512x512 image. Its a little complicated, but very flexible in that you can flip or stretch or distort the texture as it maps onto your mesh. Note that texture coordinates have the origin (u1, v1) in the top-left, and the y-axis points 'down' (screen and spatial coordinates in OpenGL usually have the origin in the bottom-left and the y-axis points 'up'). You can compute the right u and v for a specific TextureRegion using the getU, getV, getU2, and getV2 methods.

Now, in the array of floats that defines your mesh (the array you pass to setVertices) you need to set x, y, and z spatial coordinates plus u, and v texture coordinates for each vertex: final int floatsPerVertex = 5 // 3 spatial + 2 textureДЇloat meshData = new float You can have a bunch of different attributes per vertex, but I'm going to assume the only other attribute is a 3-valued Usage.Position for the x,y,z spatial coordinates. ) tells libGDX that this mesh will have two texture coordinates per vertex (traditionally, the two texture coordinates are called u and v). The new VertexAttribute(Usage.TextureCoordinates, 2. New VertexAttribute(Usage.TextureCoordinates, 2, 'y')) To draw this texture region on a mesh, you'll need to initialize the Mesh with support for texture coordinates: Mesh myMesh = new Mesh(., The region should have the basename of the original file that was used (there are more details and options if you follow some of the special naming conventions to create arrays of texture elements, but leave that off for now): TextureRegion region = myTextures.findRegion(fname) Then you can look up a TextureRegion in that atlas (that is, a specific sub-texture of the atlas). First, you create a TextureAtlas object by pointing at the text file that describes your atlas (the tool that creates the atlas will create two files: an image and a text file describing its contents): TextureAtlas myTextures = new TextureAtlas('images/packed.txt')
