mapPixelToCoords

[Kebab85]

Hello.

I'm pretty new at this and having a hard time trouble shoot this my self and i can't find the information i need on the board.

For some reason the mapPixelToCoords function doesn't seem to exist for me, i use version 2.5.1-1.
I'm not sure where i could be wrong but i try to use this from a window.  obj just as shown in your tutorial.

g++ output: ”class sf::Window” doesn't have a member with the name ”mapPixelToCoords”
(Sry bad translated from my native language)

Do i forget to declare something? Missing something when compiling? Version problems?

Sry if i explain things bad, i'm not schooled for programming and don't know all terms and bad english.

Best regards
Kebab

It's part of RenderTarget and as such part of RenderWindow and RenderTexture, but not part of sf::Window.

Not sure i understand the answer but ill dig some more with that in mind

I assume this inheritance is what you describe to me.
https://www.sfml-dev.org/documentation/2.5.1-fr/classsf_1_1RenderWindow.php

To me the tutorial looked like i should create a RenderWindow named window then access it.
But i need to somehow access this function earlier in the chain.

sf::RenderWindow::mapPixelToCoords seems to show the function, would it be correct to just use it like this?

If so, any idea why i fail to understand that tutorial?
I don't see anything there that explains that.

Again tyvm for the help.

If you not doing any rendering, you aren't using any view co-ordinates so there are none to convert to and from pixel positions. If you are using sf::Window, you refer to positions in the window by their pixels. One common usage for mapPixelToCoords is for mouse position. If you are using just sf::Window, the mouse position is in pixels and you can use that position directly.
