How to Fix Any Syntax Error in Unity (CS1003, CS1525, CS1026, etc)

In this video we will be taking a look at how to fix any syntax error in Unity. A syntax error can look like a large number of error codes. Some examples:

error CS1003: Syntax error, ',' expected
error CS1525: Invalid expression term 'int'
error CS1026: ) expected
error CS1002: ; expected
error CS1513: } expected

We'll look at how to read the errors, fix them, and prevent them from happening. The important thing to know in order to fix any syntax error is how to read them first. The basic layout of a syntax error looks something like this:

In reading order, you start with the filepath and the scriptname. Then, the numbers in brackets indicate the line the syntax error occurs on and then the second number refers to the character count. The CS1002 (or whatever number) is a reference to the error code that the computer reads and references. And finally, ; expected is telling you, in human language, what the problem is.

Knowing what the error is is only half the battle. The next part is knowing the tricks in how to solve and fix that pesky syntax error.
