- Field Detail
  - x_axis
```
public static final int x_axis
```
    Preset vectors -
    Vectors are stored as two F2Dot14 numbers stored in an int, with the x component taking up the high 16 bits and the y component taking up the bottom 16. The hypotenuse must be 1 in length. (0x4000 in F2Dot14)

  - hg
```
public static final int hg
```
    Preset round states -
    The spec defines a way of interpreting an item from the stack to form a round state consisting of period, phase and threshold for use in the SROUND instruction. This format is used instead of storing each aspect of the round state individually.
