I´m sorry to bother everyone again, but i´m in need of help. I´ve made a Game Over screen and made everything needed for it. All in all it works, but it seems i have made a mistake somewhere.
Now my character dies instantly instead of loosing energy first. Either that or maybe he takes damage continously until he dies. I can´t pinpoint where i made a mistake,
though. Maybe someone with more experience might see it? I´ve tried to make screenshots and copys of every place that might be responsible.
I hope those are the right things to look into.
