Since I made the paster plugin here are the two ways to install it.
1. Just drag the c2addon file onto the c2 editor. It should tell you it installed.
2. Rename the c2addon to a zip file. You can then get from it those four files:
There are other files in there as well to make it work as c2addon file, but they are not needed to make it work.
Anyways just make a folder named “paster” in “c:\program files\construct 2\exporters\html5\plugins” and copy those four files over.
Also as a side note if you install via dragging and dropping the c2addon file the files will be put in a folder elsewhere within the c:\users directory somewhere. Just in case you wanted to look at the source later.
Anyways, that should get you running with it. If you have any issues or questions about it feel free to ask in the paster topic. It has it’s share of issues but is still useful imo.
