Code (cont.)

Third step determines the direction, whilst only approximate the direction is often good enough for games and animation, the loop is very fast:

```Comment: determine the direction
If ((dist_x>=0) and (dist_y>=0))
Set Variable: "direction" = 90*(dist_y/normalise)
Else If ((dist_x<=0) and (dist_y>=0))
Set Variable: "direction" = -1*90*(dist_x/normalise) + 90
Else If ((dist_x<=0) and (dist_y<=0))
Set Variable: "direction" = -1*90*(dist_y/normalise) + 180
Else
Set Variable: "direction" = 90*(dist_x/normalise) + 270
End If
```

Rotate the object to the direction angle:

```Comment:   set direction of arrow
Set Property ("/arrow", Rotation) = direction
```

A final note with rotation: if the object being rotated shrinks after being rotated for a while (a bug in Flash4) you can slow down the rate of shrinkage by making the direction an int ie direction = int(direction)

Finally the code here is used to calculate the movement of a projectile from the origin to the mouse. xmov and ymov values are given, however for a real situation these values would be multiplied by the speed of the bullet

```Comment:   not required for this example
Comment:   but may be useful
Comment:  determine x and y movements for a bullet to go from origin to mouse
Set Variable: "xmov" = dist_x/normalise
Set Variable: "ymov" = dist_y/normalise
```

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
