This concept for a Rocs feather would not be a "Rocs Cape" as seen in some of the Gameboy games, but would enable Double (Triple or Multi) Jumping. Several Variable to consider:
1. How many multijumps can Link do (-1 for unlimited?)
2. How high does each additional jump take link? (Make this Small to simulate flight.)
3. How much magic, if any should it cost to do a Multi Jump?
If and when a Rocs Cape is created the same idea could be applied to it as well. Appart from basic Multi Jumping, this also open the door for flight so perhaps a good item name would be the "Roc's Wing?"
Makes no sense from a bird's eye view. Once he's jumped, he's above the Z axis... does ZC treat the Z axis as a float or int? I thought it was just a bool. Either in the air or on the ground.
However, from a side-view perspective, this makes sense, and is pretty easy to script. I'll be getting to this eventually.
Z-Axis is an int, I believe.
So, it's just accessed by Link->Z ?
You're better off using Link->Jump, though.
Here's a sample algorithm: if Link->Z is greater than a certain value, and the variable double-jump == false, Link->Jump is set to 20.
Else, if Link->Z is zero and double-jump==true, double-jump = false.
