# Get distx

## Definition

INT get_distx ( <INT angle> , <INT distance> )

Returns the horizontal distance in pixels of a specified displacement.

This is the same as `cos(angle)*distance`.

## Parameters

 INT angle - Angle, in thousandths of degrees (90° = 90000). INT distance - Length (in pixels) to measure.

## Returns

INT : The horizontal distance, in pixels, of a specified displacement.

## Notes

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

 get_distx() and get_disty()
