Stomped by

Where can i find button, Stomped by?? I'm using Crash Course.. But it's not telling where to find.. It's saying under the "Collision".. But there's just character under Collision tab.. there's nothing like Behaviour.. (behaviour have another tab i know, but in that tab there's not anything like Stomped by)

Is it an attribute? That would be a blue box if it was. To check go into the attribute tab when editing the behavior instead of the palette.

Go into the stencylforge (hit button in stencyl) and search for "stomp",  you'll find the behaviour you need there, download it
