@Override public void create() { //These variables, corresponding to the screen's width and height in cells and a cell's width and height in //pixels, must match the size you specified in the launcher for input to behave. //This is one of the more common places a mistake can happen. //In our desktop launcher, we gave these arguments to the configuration: // config.width = 80 * 8; // config.height = 40 * 18; //Here, config.height refers to the total number of rows to be displayed on the screen. //We're displaying 32 rows of dungeon, then 8 more rows of text generation to show some tricks with language. //gridHeight is 32 because that variable will be used for generating the dungeon and handling movement within //the upper 32 rows. Anything that refers to the full height, which happens rarely and usually for things like //screen resizes, just uses gridHeight + 8. Next to it is gridWidth, which is 80 because we want 80 grid spaces //across the whole screen. cellWidth and cellHeight are 8 and 18, and match the multipliers for config.width and //config.height, but in this case don't strictly need to because we soon use a "Stretchable" font. While //gridWidth and gridHeight are measured in spaces on the grid, cellWidth and cellHeight are the pixel dimensions //of an individual cell. The font will look more crisp if the cell dimensions match the config multipliers //exactly, and the stretchable fonts (technically, distance field fonts) can resize to non-square sizes and //still retain most of that crispness. gridWidth = 80;//from w w w.j a va 2s.c om gridHeight = 24; cellWidth = 14; cellHeight = 21; // gotta have a random number generator. We can seed an RNG with any long we want, or even a String. rng = new RNG("SquidLib!"); //Some classes in SquidLib need access to a batch to render certain things, so it's a good idea to have one. batch = new SpriteBatch(); //Here we make sure our Stage, which holds any text-based grids we make, uses our Batch. stage = new Stage(new StretchViewport(gridWidth * cellWidth, (gridHeight + 8) * cellHeight), batch); // the font will try to load CM-Custom as an embedded bitmap font with a distance field effect. // this font is covered under the SIL Open Font License (fully free), so there's no reason it can't be used. display = new SquidLayers(gridWidth, gridHeight + 8, cellWidth, cellHeight, DefaultResources.getStretchableTypewriterFont()); // a bit of a hack to increase the text height slightly without changing the size of the cells they're in. // this causes a tiny bit of overlap between cells, which gets rid of an annoying gap between vertical lines. // if you use '#' for walls instead of box drawing chars, you don't need this. display.setTextSize(cellWidth, cellHeight + 1); // this makes animations very fast, which is good for multi-cell movement but bad for attack animations. display.setAnimationDuration(0.03f); //These need to have their positions set before adding any entities if there is an offset involved. //There is no offset used here, but it's still a good practice here to set positions early on. display.setPosition(0, 0); //This uses the seeded RNG we made earlier to build a procedural dungeon using a method that takes rectangular //sections of pre-drawn dungeon and drops them into place in a tiling pattern. It makes good "ruined" dungeons. dungeonGen = new DungeonGenerator(gridWidth, gridHeight, rng); //uncomment this next line to randomly add water to the dungeon in pools. //dungeonGen.addWater(15); //decoDungeon is given the dungeon with any decorations we specified. (Here, we didn't, unless you chose to add //water to the dungeon. In that case, decoDungeon will have different contents than bareDungeon, next.) decoDungeon = dungeonGen.generate(); //getBareDungeon provides the simplest representation of the generated dungeon -- '#' for walls, '.' for floors. bareDungeon = dungeonGen.getBareDungeon(); //When we draw, we may want to use a nicer representation of walls. DungeonUtility has lots of useful methods //for modifying char[][] dungeon grids, and this one takes each '#' and replaces it with a box-drawing character. lineDungeon = DungeonUtility.hashesToLines(decoDungeon); //Coord is the type we use as a general 2D point, usually in a dungeon. //Because we know dungeons won't be incredibly huge, Coord performs best for x and y values less than 256, but // by default it can also handle some negative x and y values (-3 is the lowest it can efficiently store). You // can call Coord.expandPool() or Coord.expandPoolTo() if you need larger maps to be just as fast. cursor = Coord.get(-1, -1); // here, we need to get a random floor cell to place the player upon, without the possibility of putting him // inside a wall. There are a few ways to do this in SquidLib. The most straightforward way is to randomly // choose x and y positions until a floor is found, but particularly on dungeons with few floor cells, this can // have serious problems -- if it takes too long to find a floor cell, either it needs to be able to figure out // that random choice isn't working and instead choose the first it finds in simple iteration, or potentially // keep trying forever on an all-wall map. There are better ways! These involve using a kind of specific storage // for points or regions, getting that to store only floors, and finding a random cell from that collection of // floors. The two kinds of such storage used commonly in SquidLib are the "packed data" as short[] produced by // CoordPacker (which use very little memory, but can be slow, and are treated as unchanging by CoordPacker so // any change makes a new array), and GreasedRegion objects (which use slightly more memory, tend to be faster // on almost all operations compared to the same operations with CoordPacker, and default to changing the // GreasedRegion object when you call a method on it instead of making a new one). Even though CoordPacker // sometimes has better documentation, GreasedRegion is generally a better choice; it was added to address // shortcomings in CoordPacker, particularly for speed, and the worst-case scenarios for data in CoordPacker are // no problem whatsoever for GreasedRegion. CoordPacker is called that because it compresses the information // for nearby Coords into a smaller amount of memory. GreasedRegion is called that because it encodes regions, // but is "greasy" both in the fatty-food sense of using more space, and in the "greased lightning" sense of // being especially fast. Both of them can be seen as storing regions of points in 2D space as "on" and "off." // Here we fill a GreasedRegion so it stores the cells that contain a floor, the '.' char, as "on." GreasedRegion placement = new GreasedRegion(bareDungeon, '.'); //player is, here, just a Coord that stores his position. In a real game, you would probably have a class for //creatures, and possibly a subclass for the player. The singleRandom() method on GreasedRegion finds one Coord // in that region that is "on," or -1,-1 if there are no such cells. It takes an RNG object as a parameter, and // if you gave a seed to the RNG constructor, then the cell this chooses will be reliable for testing. If you // don't seed the RNG, any valid cell should be possible. player = placement.singleRandom(rng); //This is used to allow clicks or taps to take the player to the desired area. toCursor = new ArrayList<>(200); //When a path is confirmed by clicking, we draw from this List to find which cell is next to move into. awaitedMoves = new ArrayList<>(200); //DijkstraMap is the pathfinding swiss-army knife we use here to find a path to the latest cursor position. //DijkstraMap.Measurement is an enum that determines the possibility or preference to enter diagonals. Here, the // MANHATTAN value is used, which means 4-way movement only, no diagonals possible. Alternatives are CHEBYSHEV, // which allows 8 directions of movement at the same cost for all directions, and EUCLIDEAN, which allows 8 // directions, but will prefer orthogonal moves unless diagonal ones are clearly closer "as the crow flies." playerToCursor = new DijkstraMap(decoDungeon, DijkstraMap.Measurement.MANHATTAN); //These next two lines mark the player as something we want paths to go to or from, and get the distances to the // player from all walkable cells in the dungeon. playerToCursor.setGoal(player); playerToCursor.scan(null); //The next three lines set the background color for anything we don't draw on, but also create 2D arrays of the //same size as decoDungeon that store simple indexes into a common list of colors, using the colors that looks // up as the colors for the cell with the same x and y. bgColor = SColor.DARK_SLATE_GRAY; colorIndices = DungeonUtility.generatePaletteIndices(decoDungeon); bgColorIndices = DungeonUtility.generateBGPaletteIndices(decoDungeon); // this creates an array of sentences, where each imitates a different sort of language or mix of languages. // this serves to demonstrate the large amount of glyphs SquidLib supports. // there's no need to put much effort into understanding this section yet, and many games won't use the language // generation code at all.
