Just starting to code, and code returns java.lang.reflect.InvocationTargetException error

Just starting to do an elemental version of 2048, as a practice on recreations on other popular games. After coding the function structure and screen appearance, this error comes out of nowhere upon startup.


The sketch path is not set.

Can anyone rewrite part of my code and tell me which part am I doing wrong? Any help would be greatly appreciated!

EDIT: I’ve been absolutely dumb and forgot to include the code itself, but here it is now:

  /* The Grid Must Be 11 by 11
     
     119 and 120 shall be named "Avogadron (Av)" and "Davium (Da)"

Move these lines inside setup():

int[] score = int(loadBytes("score.dat"));
int[] best = int(loadBytes("best.dat"));
byte[] scoreByte = {byte(score[0])};
byte[] bestByte = {byte(best[0])};

Why? loadBytes() is defined as a both a member method and a static method. Your code references the member method which cannot be called outside setup() because sketchPath has not yet been set.

Then it returns this: score cannot be resolved to a variable, I spent quite some time trying to find out what’s wrong with the types but I can’t seem to find the error. Here’s the code:

  /* The Grid Must Be 11 by 11
     
     119 and 120 shall be named "Avogadron (Av)" and "Davium (Da)"

According to the debugger, line 53 (

    if(score[0] >= best[0]){
    best[0] = score[0];
  }
}

)
is the line causing that problem.

sorry, possibly the tip from @micycle was correct, but not complete,

if you want to use that values further, ( outside setup )
you might need to declare the variables as global,
but still fill them in setup.

int[] score;

void setup() {
  score = int(loadBytes("score.dat"));
}

void draw() [
 println(score[0]);
}

Thank you so much! I now understand the importance of setting up the variable in the right place for the right type!
