Hi,
I want to use mouse to set the starting and ending points and use a textbox to display them. One month ago, I followed the sample and it did work.
But now when I run the same code, it has something wrong. So, it is weird.
Mouse click to get the coordinates
Hi Junxuan,
From your exception it looks your clickedMouseWorldPoint is null when you click, please double check why it hadn’t been assign value in your logic.
And if you cannot solve that, please let us know what the sample you are testing? If possible, please upload your sample project and let us know your detail dll version.
Regards,
Don
