Creating Custom Chests
Step 1: Open up your database (NaviSQL, or whatever)
Step 2: Open up the table gameobject_names and look for a chest and copy the codes.
Step 3: Make a new line and change the entry ID to something that isn't currently being used.
Step 4: Change the displayID to any chest displayid you can find.
Step 5: Where, it says item ID add the item that will spawn inside the chest.
Step 6: Now, you put it in the chances of getting that object. 0.1 would be 10% 0.2 20% and 10 would be 100%.
Step 7: Now, go into the game and type .gboject spawn <entry id> 1.
