I am just trying to get into paper.js. Code works fine when they\'re inlined. But when I move them to an external file and src it there, errors starts to pop up :( Can anyon
Unfortunately, you need to run this through a server to link the two files, either setting up an XAMPP server yourself or publishing your files to a hosted server so the http://... protocol can be used rather than file:/// (your case, because you are using a localhost).
One way to do this and solve your problem is:
1) navigate to your project folder in the terminal
2) if you have python v2.x installed then run:
python -m SimpleHTTPServer
or for python v3.x:
python -m http.server
3) open up your browser and navigate to http://localhost:8000
4) select and open your .html file
It worked for me.
