A floppybird game challenge

[Mani poureini]

I need help

Hi, I have made a floppybird game on qt with a graphicseen. I also made a text which show the height base on y(), but it is reversed. How can i fix it ?
For example, when floppy bird go up, the height number which is based on y(); shows the lower number.

Hi, in screen coordinates you have zero at the top of your screen, and the max value at the bottom.

Hey hi, you need to invert the y coordinate value so that higher values correspond to higher height. You can achieve this by subtracting the y coordinate from the maximum height value.
