https://www.newgrounds.com/dump/item/a1cabb24fee6bf4b1430237f1749d83e
This is code Medals:
import com.newgrounds.API;
API.unlockMedal(“Medal Name”, positionX, positionY);
code for button below:
on(press){
import com.newgrounds.API;
API.unlockMedal(“Medal Name”, positionX, positionY);
}
and click off debug mode.
