How to make a Wire Frame actor--I'm sure it's in the documentation but can't find the link to the documentation here and doing a search didn't help me:

On Add Actor---where it says "Normal" use the drop down menu. Gives you choices of Canvas, Wire Frame or Filled. Found it randomly. : )

What to use it for? Among other things, as a sensor to stop actions like the player's being able to jump to the skies, I hope. : )

A wireframe can be used for many things. The most important thing about it is to use it for bounding boxes, because....you can resize it on the fly. That's one thing i love about wireframe actors. You can tweak it pixel by pixel until its exactly where you want it, without going back into your image editor and 'guessing' what shape it should be.

Another great thing about it ...it doesn't draw. I used wireframes for my 'homing' area of a homing missile. The wireframe, a child of the homing missile, collides with enemies, determines their type and location, and guides the missile there. Since it doesn't have to draw at all, it uses very little cpu.
