我正在使用 tmx-parser (http://code.google.com/p/tmx-parser/) 解析地图后,在 Tiled (http://mapeditor.org) 中创建地图以进行渲染。我已经将瓷砖渲染在正确的位置,但我似乎无法让它从瓷砖集中渲染正确的瓷砖。我正在使用 tiled 中的 isometric_grass_and_water 示例对其进行测试。
这是我的渲染代码。
void Map::RenderMapIsometric(SDL_Surface *SurfaceDest)
{
for (int i = 0; i < map->GetNumLayers(); ++i)
{
// Get a layer.
this->layer = map->GetLayer(i);
for (int x = 0; x < layer->GetWidth(); ++x)
{
for (int y = 0; y < layer->GetHeight(); ++y)
{
int CurTile = layer->GetTileGid(x, y);
if(CurTile == 0)
{
continue;
}
int tileset_col = (CurTile % (TilesetWidth / this->tileset->GetTileWidth()));
int tileset_row = (CurTile / (TilesetWidth / this->tileset->GetTileWidth()));
std::cout << CurTile << std::endl;
SDL_Rect rect_CurTile;
rect_CurTile.x = (this->tileset->GetMargin() + (this->tileset->GetTileWidth() + this->tileset->GetSpacing()) * tileset_col);
rect_CurTile.y = (this->tileset->GetMargin() + (this->tileset->GetTileHeight() + this->tileset->GetSpacing()) * tileset_row);
rect_CurTile.w = this->tileset->GetTileWidth();
rect_CurTile.h = this->tileset->GetTileHeight();
int DrawX = (x * this->tileset->GetTileWidth() / 2) + (y * this->tileset->GetTileWidth() / 2);
int DrawY = (y * this->tileset->GetTileHeight() / 2) - (x * this->tileset->GetTileHeight() / 2);
apply_surfaceClip(DrawX, DrawY, surf_Tileset, SurfaceDest, &rect_CurTile);
}
}
}
}
谁能指出我做错了什么?
