Dropped Item direction modifier [Unnamed]
With this code, you can choose the direction (angle) your Item (in inventory) will drop if losing it. If you have more than 1 Item in your inventory, it will at least 1 Item drop towards your set direction.
Values:
XXXXXXXX = Floating Point value of angle. See explanation below.

Explanation: The allowed values for XXXXXXXX are 0 degrees to 360 degrees single float, where 0 degrees means forward and increasing values mean a change in mathematically positive direction (counterclockwise).
I provide an example:
270 degrees (right) --> XXXXXXXX = 43870000

## lis r4, 0x4336 ## load upper part of 0x43360B60 into r4 (r4 will be overwritten two instructions ahead the Insert ASM adress)
## ori r4, r4, 0x0B60 ## load lower part 0x43360B60 into r4, 0x43360B60 is the number 65536/360 = 184.4444 in single precision (we need this value for scaling)
## stw r4, 0 (r3)
## lfs f2, 0 (r3) ## load scale factor, f2 is overwritten a few instructions further on.
## lis r4, XXXX ## load upper part of the angle float into r4
## ori r4, r4, XXXX ## load lower part of the angle float into r4
## stw r4, 0 (r3)
## lfs f1, 0 (r3) ## load the angle as single float.
## fmuls f1, f2, f1 ## apply scaling, angle is now ready for the sine/cosine function.
