General / SFML SVN Snapshots

« on: February 02, 2011, 05:14:54 pm »

Hey guys, it's been a while but I wanted to continue with my game and since i got a new PC meanwhile I wanted to download SFML2 again, but the link does not seem to work... http://sfml.svn.sourceforge.net/viewvc/sfml/branches/sfml2.tar.gz?view=tar

Any suggestions on how to get that snapshot?

Cheers,
insa

General / const reference Parameter Problem

« on: January 07, 2010, 02:17:39 pm »

The problem was that I was 100% sure that my functions were const... but in fact only the return type was :/

Thanks for the fast answers =)

General / const reference Parameter Problem

« on: January 07, 2010, 02:01:48 pm »

This is the Code as intend it to use in the future, at the moment I also pass the two integers (x and y) to initMap() (therefore it expects to get 4 parameters).

And after my four lines of assigning the temporary int/float vals, i do not touch p anymore.

Should i declare the functions I call from p as well as const?


Edit:

I just solved the problem... I thought my functions WERE const, but in fact only the return type was const.

Code: [Select]

const sf::Vector2f& getPosition(); //as i had id before, wrong

Code: [Select]

const sf::Vector2f& getPosition() const; //as i have it now, correct

Anyway, would be a const sf::Vector2f be the better choice for the return type instead of a reference to it (in terms of speed/code size)?

General / const reference Parameter Problem

.cpp

Code: [Select]

void Map::initMap(ImageHandler& ih,const PlayerD& p) {
std::vector<Tile> tmp;
float tmpPosX = p.getPosition().x;
float tmpPosY = p.getPosition().y;
int tmpTileX = p.getActTile().x;
int tmpTileY = p.getActTile().y;
}

.hpp

Code: [Select]


public:
Map(int x,int y,ImageHandler&,const PlayerD&);
private:
void initMap(ImageHandler&,const PlayerD&);

General / const reference Parameter Problem

Hey Guys,

I get this compiler error:

error C2664: 'Map::initMap' : cannot convert parameter 4 from 'const PlayerD' to 'PlayerD &'

on that code:

Code: [Select]

Map::Map(int x,int y,ImageHandler& ih,const PlayerD& p) {
initMap(ih,p);
}

initMap is supposed to take a const PlayerD& as well...
