So im making a tilemap and rendering it to the scene . But it got really weird and mess up
I cant find what is wrong with it . Help!
This is the main code ( run in main.cpp)
private:
//display properties
int nTileWidth;
const static int nTileVisY = 16;
const static int nTileVisX = 16;
//level properties
const static int nLevelWidth = 32;
const static int nLevelHeigth = 32;
std::string sLevel;
std::fstream stream;
//camera
View camera;
//the tilemap
TileMap tilemap;
//the draw map
int defMap[nLevelWidth * nLevelHeigth];
int drawMap[(nTileVisX+1) * (nTileVisY+1)];
void Create() override
{
std::cout << "Create 1 \n";
stream.open("map.txt");
//the level
sLevel += "................................";
sLevel += "................................";
sLevel += "................................";
sLevel += "................................";
sLevel += "................................";
sLevel += ".......#######.........#######..";

THis is the tilemap code from sfml tilemap tutorial
