Feature requests / Manually setting Z-order

But then if you modify the z-value of a sprite, don't you invalidate the multi-set?

The best solution would be to use accessor/mutator functions which automatically sort the list if the z value has changed.

Here's a Z-sorted sprite example (psuedo-C++):

Code: [Select]


class ZSprite : public sf::Sprite
{
  private:
    double z;
    std::list<ZSprite*>* list;
   
  public:
    ZSprite([[Sprite args...]],
                double z=0.0,
                std::list<ZSprite*>* list)
    {
        this->z = z;
        this->list = list;
    }

    double GetZ() { return z; }

    void SetZ(double value)
    {
        if( z != value )
        {
            z = value;
            [[sort your list here...]]
        }
    }
};
