so lets start by what this means

 

all the "at package.name.classname.method(File.java: line#)"

is called the stack trace, it says where and how the program crash.

in your case it says:

java.lang.IllegalArgumentException

meaning you called a method with soemthign that shouldn't be

its followed by:

n must be positive

which explain why its not a legal argument

and with the stack trace:

at java.util.Random.nextInt(Random.java:300)

its in file java.util.Random in methdo nextInt in the file Random.java at line 300

and thsi method is called from:

at tutorial.EventManager.addOreSpawn(EventManager.java:57)

which is YOUR class (always assume that everything under java.* is correct and working, always assume that YOU are not using the code properlly)

so its in file EventManager.java at line 57 and its in method addOreSpawn

which btw is called from:

at tutorial.EventManager.generateSurface(EventManager.java:24)

generateSurface line 24 in file EventManager, but we assume that your code is fucking up ...

 

line 57 of EventManager (well actually 57+- 2 lines):

int posX = blockXPos + random.nextInt(maxX);
int posY = minY + random.nextInt(diffBtwnMinMaxY);
int posZ = blockZPos + random.nextInt(maxZ);

remember i dont have line numbers and im not goign to count them

so one of these receives a number under 0 (remember earlier: n must be positive)

you can clearly see that by doign a println right before calling those

System.out.println("value of maxX: "+maxX);
int posX = blockXPos + random.nextInt(maxX);
System.out.println("value of diffBtwnMinMaxY: "+diffBtwnMinMaxY);
int posY = minY + random.nextInt(diffBtwnMinMaxY);
System.out.println("value of maxZ: "+maxZ);
int posZ = blockZPos + random.nextInt(maxZ);

 

now if you run thsi the logs will look like this:

"value of maxX: 3

value of diffBtwnMinMaxY: -1

value of maxZ:  5

so you know that yes you are fucking up somewhere

btw i made up those numbers, i dont know what the actual output will be

 

since you know you are sending negative numbers to the method nextInt you have to find why you are arriving at these resutl and how to fix it
