int Character.z;

Gets/sets the character's current Z position. This allows the character to levitate off the ground, whilst still retaining its normal Y co-ordinate for baseline calculations and regions.

Normally this is set to 0 (ground-level), but you can increase it to make the character float.

Example:

while (player.z < 20) {
  player.z++;
  Wait(1);
}
