So I'm trying to use this p5 projection mapping addon
http://omershapira.com/blog/2013/02/p5-texture-map-a-projection-mapping-addon-for-processing-2-0/ because I need to be able to map triangles.
Along the way I've had to convert alot of commands from what I assume is a result of 2.0+. I've come across this one and I'm not sure how to replace/fix it..
"Could not register mouseEvent() for ProjectionMapGL$Mapper@50a649" -
Anybody know what I need to replace these two statements with?
Entire code:
