It's not my project, is it?
I bought Construct2 two years ago, started working with it much earlier than that and have never needed that plugin, so I won't be needing it now..
Maybe your project needs it, but that doesn't mean I will install it..
I'll be glad to help you on your game, but that doesn't mean I should clutter up my construct2 plug-ins-menu with stuff I'll never use..
The question is Why..
Why is it a requirement?
Why would you expect someone who doesn't need it to download it?
The question could also be Why not..
Why not use the build in platform behaviour?
BTW, my explanation about the collisionsprite should work regardless of what behaviour you are using..
So all you will have to do is set up events for what I said..
I just won't be able to do it for you..
