This might be an Xcode 4-only issue, though I figured one or two people here have come across it.
After following RevTorA's tutorial for a C++ Tile Engine, I came across this nasty bug when trying to set a position to an element. It seems that for us Mac devs, EXC_BAD-ACCESS points out a memory issue. The only problem is that Xcode isn't giving me a way to fix it, as would usually be the case.
The app would build and then run almost perfectly, except that this issue messes up rendering pretty badly. I was wondering if anyone here could help me out by pointing out how to fix it.
Tile.h#ifndef Tile_h
#define Tile_h
#include <iostream>
#include <SFML/Graphics.hpp>
class Tile
{
private:
sf::Sprite baseSprite; // The trouble child.
public:
Tile(sf::Texture& texture);
~Tile();
void Draw(int x, int y, sf::RenderWindow* renderWindow);
};
#endif
Tile.cpp#include "Tile.h"
Tile::Tile(sf::Texture& texture)
{
baseSprite.setTexture(texture);
}
Tile::~Tile()
{
}
void Tile::Draw(int x, int y, sf::RenderWindow* renderWindow)
{
baseSprite.setPosition(x, y); // This is where the EXC_BAD_ACCESS occurs.
renderWindow->draw(baseSprite);
}
Those were the Tile files, which are the origin of the issue. These are the two compadres that reference Tile at some point.

Anyone?
