Hello sorry I keep asking about errors but I am new.
I am making a ping pong game, an arduino with a proto-shield and an LCD.
I wrote a 700 line program, so no suprise there is an error.
There used to be three errors, now there is about 100.
Here is the 1/2 the code:

Code:

  ;lcd.print("Press go 2 play")
    ;val = digitalRead(inPin); 
  ;if (val == LOW)
  ;lcd.print("start in 3")
  ;delay(1000)
  ;lcd.clear()
  ;lcd.print("start in 2")
  ;delay(1000)
  ;lcd.clear()
  ;lcd.print("start in 1")
  ;delay(1000)
  ;lcd.clear()
  ;lcd.print("GO!")
  ;delay(1000)
  ;lcd.clear()
  ;lcd.write(2)
  ;lcd.print("      ")
  ;lcd.write(5)
  ;lcd.print("       ")
  ;lcd.write(2)
  ;lcd.setCursor(7, 0)
  ;lcd.write(3)
  ;delay(100)
   ;val = digitalRead(0); 
  ;if (val == LOW)
  x = x+1
 
    ;else
{
  break;
}

 
 
  //I WAS HERE
  ;lcd.setCursor(6, 0)
  ;lcd.write(3)
  ;delay(100) 
  ;if (pushButton == HIGH) {
  x = x+1
  }
   

  ;lcd.setCursor(5, 1)
  ;lcd.write(0)
  ;delay(100)
  ;if (pushButton == HIGH) {
  x = x+1
  }
   
  ;lcd.setCursor(4, 1)
  ;lcd.write(1)
  ;delay(100)
  ;if (pushButton == HIGH) {
  x = x+1
  }
 
  ;lcd.setCursor(3, 1)
  ;lcd.write(2)
  ;delay(100)
  ;if (pushButton == HIGH) {
  x = x+1
  }
 
  ;lcd.setCursor(2, 1)
  ;lcd.write(3)
  ;delay(100)
  ;if (x > 4)
{
  goto arduino; 
}
;else
{
goto gameover;
}
//after the first bounce, here is arduinos turn!!!

  }



 
 
        ;}
       
       
gameover;
lcd.print("   GAME OVER!   ")
delay(10000)

That is the end of it...

[Reply #2 on:]

I skiped most of the code because it was a ~500 line GIF

[Reply #3 on:]

PS. I skiped half the ERRORs by putting semi colons before most statements.

[Reply #4 on:]

Semicolons go at the end of statements.  If it says expected ; before ...  that means you left one out on the line above.  No line should EVER start with a semicolon.

[Reply #5 on:]

Everything after a semicolon is not a comment, it is another statement. Use // to comment out lines, or /* ...*/ pairs if you are a picky C programmer. 8^)

[Reply #6 on:]

I'm fairly certain this guy is a troll, because in numerous threads, he's been told about his semicolon issue and he completely ignores us.

[Reply #7 on:]

Sorry about that, I am not a troll, lol.
But the others who tried to explain it didn't really make it clear.
I fixed that problem but is there anything to debug, particularley variables, most of the errors are about variables?
Sorry about not listening to the semi colon thing you guys are the only help I have understood.

You simply need to read and understand the error message, and look at the piece of code it relates to. If you can't make sense of it post your code (the whole file that causes the error) and the error messages that you get when you try to compile it, and usually somebody will explain what the message means.

[Reply #9 on:]

As I just said in another thread, look at the first error, fix it and recompile. Rinse and repeat. Your first few errors appear to be that you haven't declared variables. This:

Code:

x = 0

pushButton = 0;

Should likely be this:

Code:

int x = 0;
int pushButton = 0;

Similarly, the next couple of issues are items not declared in loop. But please, for the love of the FSM, sort those semi-colons out.

[Reply #10 on:]

Thank you very much wildbill, you have been most helpful. But back to the point, I debugged a few errors but I got stumped at this error:
call of overloaded 'write(int)' is ambiguous
here is the code it is in

Code:

;lcd.write(0)

[Reply #11 on:]

sorry about the semi colon there I copied it before I changed it!

[Reply #12 on:]

You should probably go through a few of the example projects just to see what code should look like.

 

[Reply #13 on:]

ya thanks, but I actaully copied and pasted, from example code and I have looked at almost all of them.

[Reply #14 on:]

Now I'm certain you're trolling. Nobody could genuinely be that obtuse.
