This is a scripting issue, not a 2D issue.

The error message is pretty clear: it expects a semicolon (;) in this context. The (19,76) part is telling you what line and column it got confused.

Line 19 starts your loop. A "for loop" syntax is like this:

Code (CSharp):

1. for (
2.         <initialization> ;
3.         <condition> ;
4.         <step>
5.       )
6. {
7.       <statements>
8. }

You only gave the <initialization> and <condition> parts, all three need to be there.

 

Nothing special here, you're just making typing mistakes. Don't do that, you will be required to fix them all.

Here is how you can get started fixing your own errors:

Remember: NOBODY here memorizes error codes. That's not a thing. The error code is absolutely the least useful part of the error. It serves no purpose at all. Forget the error code. Put it out of your mind.

The complete error message contains everything you need to know to fix the error yourself.

The important parts of the error message are:

- the description of the error itself (google this; you are NEVER the first one!)
- the file it occurred in (critical!)
- the line number and character position (the two numbers in parentheses)
- also possibly useful is the stack trace (all the lines of text in the lower console window)

Always start with the FIRST error in the console window, as sometimes that error causes or compounds some or all of the subsequent errors. Often the error will be immediately prior to the indicated line, so make sure to check there as well.

Look in the documentation. Every API you attempt to use is probably documented somewhere. Are you using it correctly? Are you spelling it correctly?

All of that information is in the actual error message and you must pay attention to it. Learn how to identify it instantly so you don't have to stop your progress and fiddle around with the forum.
