1. Are there any FPS drops while using this? If so, how big are they?
2. Does this work with 8-diagonal and pixel movement? (Compability with Cyclone movement plugin?)
3. Am I allowed to use this in an open-source game by deleting the plug-in file from the plugins folder so that if someone wants to compile it, they have to buy this plugin themselves?
1) That would depend on (a) Your Animation loading size and (b) Your audio loading size and even then, it is very low.
2) It's its own entity with 2D direction keyboard and mouse movement. It does not need any movement plugin nor will it work with any as it does not work off of the map scene. It is a "stand-alone" extension plugin.
3) Do you mean you will combine the plugin into another? Convert the plugin into a node binary? Simply change the folder the plugin is called from?
