If you press play, a 64 bit Editor is trying to run a 32 bit plugin, so it says 'hey, dummy, I'm a 64 bit editor so I need a 64 bit version of your plugin to use when you're running your game in me.

I didn't realize this, but it makes sense now. Why? Because a 64 bit editor can't read a 32 bit plugin. 'Well duh,' you say, but I didn't know that.īecause I'm using 64 bit Unity and wanted to make a 32 bit build of the game, I needed two plugins:ġ) A 64 bit version of the plugin for the Editor. I.e., when I built a 32 bit version of the game with the 32 bit version of my plugin, the built game worked fine, but it wouldn't work in the editor because 64 bit Unity wants a 64 bit version of the plugin. I'm pretty sure that 64 bit Unity needs a 64 bit version of my plugin in order for the editor to be able to use it. I'm not entirely sure this is all correct, but it's the best I've been able to figure out: Ok, I think I've finally figured this out so will explain it here for future generations.
