When accessing https://developer.playcanvas.com/en/user-manual/scripting/legacy/debugging/ I get the following statement:
“In order to debug your scripts, select the Sources tab in Developer Tools. Open the ‘navigator’ by clicking the icon in the top left corner of the Sources pane. You should see something similar to what is shown below:”
and then a photo that does not refer to anything meaningful :-/
Found out (partially) that one has to use the browsers debugging tools … thx anyway (otherwise: please read my “Major bug” feedback as well - much more important )
