i have been trying to make a game with multiple worlds and ive had this problem with variables. i need a way to make them castable from any world, but everything is from level1 in my code. i just need some type of world class variable that goes between classes.
this is all the code i used and the error i got:
warning:
java.lang.ClassCastException: Level2 cannot be cast to Level1
at Player.hurt(Player.java:139)
at Player.act(Player.java:23)
Level1 World:
my Player (uses most of the Variables, just given as an example as most classes use world variables)
all i'm trying to find it a way to bring this variable code into my next world and worlds after, but as said i have no clue how to do this. any help will be appreciated and thank you for the help.
