[check] Java error: Invalid method Code length ... in class file org/python/pycode/... (script too large)

[RaiMan]

***** problem is caused by a Java implementation limit:

A compiled class file cannot be larger than 64 KB.

Since internally when running a script, this is compiled into a class file, and might be too large.

I will try to find some assistance help for a scripter, to know, when his stuff is too large.

So you have to divide your script into smaller packages and use import

I wrote a 500 line sikuli script to play baccarat on an online casino.
The script was working fine so I decided to add some conditional statements to handle specific events in the game.
I added an additional 2500 lines of code and when I run it I get the following error - what does it mean ?

[error] script [ casino.com] stopped with error at line --unknown--

The error you encountered is due to your script exceeding the Java Virtual Machine (JVM) method size limit of 64 KB. This happens when the compiled bytecode of a single method in your script is too large.

To resolve this issue, follow these steps:

Divide Your Script (https://s9game.app/): Break your large script into smaller, more manageable parts. Instead of having one massive block of code, split it into multiple smaller scripts or functions.

Use Modular Design: Organize your code into modules or separate functions that can be imported into your main script. This approach keeps individual sections of your code concise and within the size limits.

Refactor Code: Identify and refactor any large conditional blocks or repeated code into separate functions. Each function should perform a single task or handle a specific part of the logic.

By dividing your script into smaller pieces and using a modular approach, you will avoid the method size limit and improve the maintainability of your code.
