Hello geo123,

Thank you for your post.

While our support team cannot debug this script for you, we can assist you with debugging and guiding you through fixing the compile errors if you are interested in resolving the errors yourself. If you are, please provide a screenshot of the compile errors.

If you are using an external AI tool those generally cannot create valid NinjaScript, I have included some information about that below.


From our experience at this time, ChatGPT and other AI models are not quite adequate to reliably and consistently generate valid compilable NinjaScripts that function as the user intends. We often find that the AI-generated code will call non-existent properties and methods, use improper classes or inheritance, exclude necessary components such as using statements, and may have incorrect logic.

We highly encourage that you create a new NinjaScript yourself using the NinjaScript Editor, and use the code generated by ChatGpt as more as suggestions and guide than the actual code generated.

Below is a link to a forum thread that discusses ChatGPT and it's limitations.

While it would not be within our support model to correct these scripts at user request, we would be happy to provide insight for any direct specific inquiries you may have if you would like to create this script yourself. Our support is able to assist with finding resources in our help guide as well as simple examples, and we are happy to assist with guiding you through the debugging process to assist you with understanding unexpected behavior.

Below I am providing a link to a support article with helpful resources on getting started with NinjaScript and C#.
