Re: Create a game map?
Re: Create a game map? Hello,You don't iterate through tiles, you iterate through polygons. That way you can create a world that is endless and if you only have 1 object, then you're only looping through that one object.Look at:https://github.com/frastlin/PyAudioGame … ui/grid.pyThe Grid class is self-contained and is what you are looking for. It's extremely fast and can hold thousands of objects.

Re: Create a game map?
Hi,Probably an unpopular suggestion, but worth chucking out there:I know there's lots of boilerplate code in here, but I've taken the _Base class from my pyrts project.With the below code you can instantiate maps and tiles with relative ease. Of course there's no provision for storing objects, but that's only a matter of extending what I've written.I use this kind of setup a lot.

Re: Create a game map?
Re: Create a game map? I'm bringing this up because I do want to try an array and compare it to my system.I figured out how to create a numpy 3d array, use the zero's function with x, y, and z dimentions. Here's the problem:import numpy as np lst = np.zeros((5000, 5000, 5000)) ValueError: array is too big; `arr.size * arr.dtype.itemsize` is larger than the maximum possible size.This is, without a doubt, a huge array. It is also something that I may not need. However, an array of 1000 of each entry is also something that numpy hates, and I could definately see myself reaching 1k tile size.However, my solution, to loop through tiles, is also really slow (5000 * 5000 * 5000 or 1000 * 1000 * 1000) entries to loop through? No thanks. Ideas/tips?Edit:Even 200 * 200 * 200 lags like a bitch when I loop through tiles. Yeah no, I will try and switch away from my systemas soon as possible.

Re: Create a game map? Look for a point in polygon algorithm in your language of choice, and just use polygons.Python:https://pypi.org/project/collision/_javascript_:https://www.npmjs.com/package/flatten-jsFor 3D objects, you'll want something like Panda3D or BabylonJS.

Re: Create a game map?
Re: Create a game map? For instance, you may asign 1 through 100 to tile types, 101 through 200 to door types, 201 to 300 to walls. And I'm organizing it like that because you don't know how many tiles/walls you're going to have, And you might gradually increase the amount of them so you reserve 100 for each catigory. However, i meant putting tiles as string in an array and parsing each element to get each tile's left and right boundaries.

Re: Create a game map?
Re: Create a game map? @6, I would modify the index operator to allow me to pass in a tuple, which reads a bit smoother, then define a class as an enum to hold all my tile types:from aenum import Enum class Tile(Enum, start=0): Wall Empty #... if map[(player.x, player.y)].type == Tile.Wall.value: #Tile is a wall elif ...: # ...Things like that.

Re: Create a game map?
Re: Create a game map? @4/5, really? Could you explain a bit as to why post 2's approach wouldn't be that good? I am asking because I can't picture having multiple tile sets in a 2d array, not unless I want to do something like this:if map[player.x][player.y] == -1: #wall logic should go hereNow, how do I determine what wall sound to play?Or something like thisif map[player.x][player.y] == 0: #Wood tile play soundif map[player.x][player.y] == 1: #Ash tile play sound.With post 2's approach I would be able to tell what sound to play by checking the tile type, how would you two go about implementing multiple tiles in a 2D array, though?

Re: Create a game map?
Re: Create a game map? Nuno You eventually need to check every square the player walks on, and perhaps the surrounding squares so the array is your best bet. It's fast and performant URL: https://forum.audiogames.net/post/461134/#p461134 -- Audiogames-reflector mailing list Audiogames-reflector@sabahattin-gucukoglu.com https://sabahattin-gucukoglu.com/cgi-bin/mailman/listinfo/audiogames-reflector
Re: Create a game map?
Re: Create a game map? a 2D array is the best your going to get. Just check each square as the player navigates, and use NumPy (don't use lists of lists, vectors of vectors, etc.) or the equivalent for your language of choice. Since you're accessing them directly by index your most likely going to get O(1) performance, or extremely close to it.I'm telling you not to use lists of lists/vectors of vectors/... because those will create massive levels of indirection and tons of cache misses, and they're not built for that. Use a dedicated library that is able to represent a 2D vector properly without all the problems. You could make your own 2D vector class, too, though you then need to figure out if you want row-major order or column-major order. C, for example, uses row-major order. If you want to use row-major order, then create the list and resize it to map width * map height, then access it as map width * row + column in the index operator function.

Re: Create a game map?
Re: Create a game map?
you could create a class which is the map interface and then create classes that can represent your tiles, zones, and stuff. I'd do something like the followingclass MapObj{ // a map object // this is the base class from where all the other objects such as tiles and zones can inherit // sorry if the code doesn't follow c#'s code convention, feel free to adjust it. public int minX; public int maxX; public int minY; public int maxY; // if you wanted a 3d map you could add minxZ and maxZ too. public MapObj(int minx, int maxx, int miny, int maxy) { this.minX = minx; this.maxX = maxx; this.minY = minY; this.maxY = maxY; } public bool covers(int x, int y) { // here you could define a function that would return true if the set of coordinates are covered from the tile }}Then you could create a tile like thispublic class tile : MapObj{ public string type; public tile(int minx, int maxx, int miny, int maxy, string type) : base(minx, maxx, miny, maxy) { this.type = type; }}you could implement then a function get_tile_type() which would return the type of the tile. if the type is wall, then boom you have it.If you want I could send you the map class that I've made so that you can fully use it.
