Get Size and Position of texture/sprite

[SEnergy]

Hello,

I'm trying to get position and size of sprite and texture but I'm getting this error:

error is on wsprintf...

Code: [Select]

Unhandled exception at 0x74df9d60 in Lucid Dreaming.exe: 0xC0000005: Access violation reading location 0x00000320.
part of code:

Vector2u PlayerSize = tBackground[0].getSize();
                                char test[512];
                                wsprintf(test, "%s", PlayerSize);
                                MessageBox(NULL, test, NULL, NULL);

and position is returnin NULL value

Vector2f PlayerPosition = sBackground.getPosition();
                                char test[512];
                                wsprintf(test, "%s", PlayerPosition);
                                MessageBox(NULL, test, NULL, NULL);

also is there any way to return them as int x,y?

%s expects a null-terminated C string, nothing else (especially not a sf::Vector2).

Look at the documentation of the sf::Vector2 class to find out how to extract its x and y components.

What you want is to use either %u (unsigned integer) or %f (float) for each of the X and Y values in the vector.

For example:

Vector2u PlayerSize = tBackground[0].getSize();
char test[512];
wsprintf(test, "%u, %u", PlayerSize.x, PlayerSize.y);
MessageBox(NULL, test, NULL, NULL);

Or better: use the C++ functions instead of this unsafe C stuff.

std::ostringstream oss;
oss << PlayerSize.x << PlayerSize.y;
std::string str = oss.str();
