How to use RenderTarget?

[Poraft]

I used some older version of SFML2, where I used RenderWindow->ConvertCoords();
But in the rc I can't use that anymore, I can't find out how to use RenderTarget I can't even declare it.

Gives the error:

G:\CBprojects\PazookaCB\ingame.h|29|error: cannot declare field 'InGame::RT' to be of abstract type 'sf::RenderTarget'|
G:\SFML-2.0-rc\include\SFML\Graphics\RenderTarget.hpp|52|note:   because the following virtual functions are pure within 'sf::RenderTarget':|
G:\SFML-2.0-rc\include\SFML\Graphics\RenderTarget.hpp|206|note:    virtual sf::Vector2u sf::RenderTarget::getSize() const|
G:\SFML-2.0-rc\include\SFML\Graphics\RenderTarget.hpp|345|note:    virtual bool sf::RenderTarget::activate(bool)|
||=== Build finished: 1 errors, 0 warnings ===|

Please provide me an example.

hmmm, maybe try reading the documentation?




....Quite a bit back the naming convention was changed to camelCase so reading always helps. Also read the error, "error: cannot declare field 'InGame::RT' to be of abstract type" means quite a bit. Try googling abstract, because abstract classes cannot have objects created from them.

And you probably want a sf::RenderWindow, not sf::RenderTarget which is its abstract base class.

Thanks, I solved it.
