can someone guide to were I can start to learn for Opensim scripting. I looked in YouTube and all I fin is for SL and I been told that does not totally work with Opensim so is it worth starting there then cause I would have no clue to how to modify it for Opensim

You can also use ChatGPT. Paired with CODEX and VSCode, you'll be amazed at what you can accomplish.
To add a bit more detail to that:
We use ChatGPT alongside VS Code and Codex mainly as a working assistant, not a replacement for learning.
Some concrete ways it helps with OpenSim scripting:
• Porting SL scripts to OpenSim
You can paste an SL LSL script in, tell it “this is running on OpenSimulator,” and it will flag unsupported functions, suggest OSSL replacements, or adjust behavior where OpenSim differs.
• Explaining script errors that won’t save or compile
If a script refuses to save in OpenSim, pasting the error message and script usually gets you a clear explanation of why and what to change. This is especially useful for permission issues, missing events, or OSSL restrictions.
• Writing small utility scripts fast
Doors, menus, teleporters, lighting controllers, rez systems, windlight tools, security orbs, etc. You can describe what you want in plain English and then tweak the output to fit your needs.
• Learning by modification instead of guessing
Ask why a function behaves differently in OpenSim, or what the safe/allowed alternative is. This helps you actually understand the differences instead of trial-and-error guessing.
• OSSL awareness
If you explicitly say OSSL functions are allowed, it can suggest OpenSim-only solutions that SL simply cannot do, like region control, NPC handling, environment settings, or estate-level tools.
VS Code just makes this easier by giving syntax highlighting, search, and version control, while ChatGPT helps with reasoning and translation between SL and OpenSim quirks.
Bottom line:
Learning LSL for SL is still absolutely worth it.
OpenSim is close enough that most knowledge transfers, and tools like ChatGPT help bridge the gaps where it doesn’t.

The open sim specific functions are documented here:
http://opensimulator.org/wiki/OSSL_Implemented
The status of implemented LSL functions here:
http://opensimulator.org/wiki/LSL_Status/Functions
Full documentation here:
http://opensimulator.org/wiki/Scripting_Documentation
Most things work, but some are implemented a bit differently so small tweaks to some SL scripts might be needed to make them work in open sim.
if you have an SL script that wont save in open sim, then chat GPT has helped me in the past by telling it the error and providing the script and stating that its an lsl script running in open simulator and its allowed to use open simulator functions if required.
Hope this helps :)
