Tile Maps Help
Author
Hi i have created a tile map class but having problems difining my map after instantiating it. For example if i declare somewhere in main
CMap *map1 = new CMap("SKYLEVEL1", 1, 2, 2) //last 2 numbers
//r width and height of map
the problem is when i define what textures go into a map usually you would declare this like
int defmap[2][2]={0,0
0,0
};
i don't know how to pass defmap to map1 so the tiles get assigned to it.
the class CMap has vector of vectors i.e. vector< vector<int>> m_TileMap;
how do i create a function in CMap that takes defMap as a parameter and assigns it to m_TileMap?????
I don't really understand your question.
But what I can make out of it is that you want to pass an array as an argument to a function?
Using this method you can pass around the entire map as just an 'int*'

class CMap{ public: CMap (const char* text, int num, int width, int height, int defmap[2][2]);};CMap::CMap (const char* text, int num, int width, int height, int defmap[2][2]){}int main (void){ int defmap[2][2] = {{1, 2}, {3, 4}}; CMap* map = new CMap("SKYLEVEL1", 1, 2, 2, defmap);}Using this method you can pass around the entire map as just an 'int*'
inline unsigned int access2D (unsigned int x, unsigned int y, unsigned int width){ return (y*width)+x;}class CMap{ public: CMap (const char* text, int num, unsigned int width, unsigned int height, int* defmap);};CMap::CMap (const char* text, int num, unsigned int width, unsigned int height, int* defmap){ defmap[access2D(1, 1, width)] = 42;}int main (void){ unsigned int width = 2; unsigned int height = 2; int* defmap = new int[width*height]; CMap* map = new CMap("SKYLEVEL1", 1, width, height, defmap);}

the problem is i want to define the map like int defmap[2][2] = {{1, 2}, {3, 4}}; so i can properly assign the textures of the map
how would
unsigned int width = 2;
unsigned int height = 2;
int* defmap = new int[width*height];
CMap* map = new CMap("SKYLEVEL1", 1, width, height, defmap);
know what textures i would want to load i.e with
int defmap[2][2] = {{1, 2}, {3, 4}}; corresponds to which texture sin the array to use?
how would
unsigned int width = 2;
unsigned int height = 2;
int* defmap = new int[width*height];
CMap* map = new CMap("SKYLEVEL1", 1, width, height, defmap);
know what textures i would want to load i.e with
int defmap[2][2] = {{1, 2}, {3, 4}}; corresponds to which texture sin the array to use?
What you should be doing is allocating space for your tile indices as a single-dimensional array, but accessing it multi-dimensionally.
For example, your tile data is integers, so that's easy:
Don't forget to incorporate bounds-checking into your code, the above can easily produce errors if invalid values are passed to the functions.
For example, your tile data is integers, so that's easy:
int gettile(int* map, int x, int y){ return map[y * map_width + x];}void settile(int* map, int x, int y, int new_tile){ map[y * map_width + x] = new_tile;}void examplefunc(void){ // Allocate the map int map_width = 1000; int map_height = 1000; int* map = new int(map_width * map_height); // get the tile at character position int x = 100; int y = 100; int current_tile = map[y * map_width + x]; // the same as... current_tile = gettile(map, x, y); // set a map tile int new_tile = 6; map[y * map_width + x] = new_tile; // the same as... settile(map, x, y, new_tile); // Later on, deallocate the map memory delete [] map;}Don't forget to incorporate bounds-checking into your code, the above can easily produce errors if invalid values are passed to the functions.

Ok here is my source
Ok now what i i need is a method in that class that will take this a 2d dimensional array and assign it to the vectors in that class so
i want something like this
int MAP[2][2] = {0,0
0,0};
and then MAP can be passed to map1 which will build the map but how can i do this???
CMap *map1=new CMap("SKYLEVEL1", 1, 2, 2, MAP);

Is this what you're looking for?
inline unsigned int access2D (unsigned int x, unsigned int y, unsigned int width){ return (y*width)+x;}CMap::CMap(string mapName, int level, int images, unsigned int w, unsigned int h, int* defmap){ for (int x = 0; x < w; x++) { for (int y = 0; y < h; y++) { m_TileMap[x][y] = defmap[access2D(x, y, w)]; } }}

Ahh so with that method i could do this
int MAP[5][5]={0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0};
CMap *map1 = new CMap("SKYLEVEl1", 1, 5, 5, &MAP);
will this work with the above code mentioned.
int MAP[5][5]={0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0};
CMap *map1 = new CMap("SKYLEVEl1", 1, 5, 5, &MAP);
will this work with the above code mentioned.
