Hello, i think your program is nice but i've got an error:
Uncaught TypeError : cannot read property 'prototype' of undefined
localhost/objref.js, line 8 (col 30)
This may be a bug in Construct 2 or a third party plugin or behavior-
please report him to the developer following the bug report guidelines.
Subsequent error will be logged to the console.
Thank you if you can help me.
