You Pin the animation to the invisible sprite. Again, do the tutorial, and it is all explained.

I am doing the tutorial. I just didn't think that part was explained well. Thanks for your help though.

If you read through the Building a platform game - a beginner's guide tutorial it explains what's going on. Your collision polygons change for each frame. By using an invisible rectangle sprite and pinning your animation to it, you get both the correct collision rectangles and smooth movement.

I'm not understanding what it means by the "player object can be positioned on top of that."

Hello,

        I am new to C2 and am making my first animation. I made my cat and am just trying to get him to walk across the screen. The issue I'm having is that it's like the floor is ignored for part of the animation and my character sinks below it. What is wrong with it?

Here is the link to download my project from Google Drive:

docs.google.com/file/d/0B7J_u-N39CbcZjh0b3dkRFNjZ2s/edit

I tried to add audio to my project and got a yellow bar across the top that said this object is unavailable to the entire project. Now, when i try to add it again, there isn't even the option for audio, just user media. What am I doing wrong?

nevermind...you just right click...

I am currently going through the platforming tutorial. When I click "Edit" next to Animations, the animation window only shows "Default" but not "Running" or "Standing". How can I add more animations to the animations window?
