I was wanting to make a new mysterybox system because the one i have is old dated if you have any good ones please share them thanks.

Make a new java file named MysteryBox.java and add all this in it:

And put that file in server>Model>Players>Content

package server.model.players.Content;
 
import server.model.players.Client;
import server.util.Misc;
import server.model.players.PlayerHandler;
import server.Server;

                        c.sendMessage("You open the box to find nothing. What bad luck.");//If you got 0, it says you find nothing.
                else
                        c.sendMessage("You open the box and find " + (amountToGive > 1 ? "some " : "a ")
                                        + c.getItems().getItemName(itemToGive) + ".");//If more than one item, use some, otherwise use a.
        }
}

Somewhere in ClickItem.java add this:

				if (itemId == 6199) {
				MysteryBox.openBox(c);
				}

If you get any errors, comment them, I should answer in the following minutes

 

OT: I know Dan is using a custom server and the reward are custom items, so just change the rewards to match your items to your liking

Read the OT

You can easily write your own just by copping old one and take little bits.

Yeah basically just take what I just posted and change the rewards

If the old one still works, but you just want to change the rewards, then just change that part? D:
