Wind

Wind

A base class for creating Wind. Wind direction and velocity by down-range distance.

Attributes:

Name	Type	Description
velocity	Velocity	speed of wind
direction_from	Angular	0 is blowing from behind shooter. 90 degrees is blowing from shooter's left towards right.
until_distance	Distance	until which distance the specified wind blows
MAX_DISTANCE_FEET	float	Optional custom max wind distance

Parameters:

Name	Type	Description	Default
velocity	Optional[Union[float, Velocity]]	speed of wind	None
direction_from	Optional[Union[float, Angular]]	0 is blowing from behind shooter. 90 degrees is blowing from shooter's left towards right.	None
until_distance	Optional[Union[float, Distance]]	until which distance the specified wind blows	None
max_distance_feet	Optional[float]	Optional custom max wind distance	cMaxWindDistanceFeet

Example

This is how you can create a wind

from py_ballisticcalc import Wind
wind = Wind(
    velocity=Unit.FPS(2700),
    direction_from=Unit.Degree(20)
)
