==Definition==
'''INT''' get_disty ( <'''INT''' angle> , <'''INT''' distance> )

Returns the vertical distance in pixels of a specified displacement.

== Parameters ==
{|
| '''INT''' angle || - [[Angle]], in thousandths of degrees (90° = 90000).
|-
| '''INT''' distance || - Length (in pixels) to measure.
|}

== Returns ==
'''INT''' : The vertical distance, in pixels, of a specified displacement.

== Notes ==
This function returns the height of an imaginary rectangle who's opposite corners are the specified distance apart, at the specified [[angle]] from each other.
