Overview

WSF_FIRES_MOVER provides movement along a ballistic trajectory that assumes a first-order drag (drag proportional to the first power of the velocity). The resulting trajectories are deterministic and characterized by a single parameter. This simplicity allows one to easily hit a location or target with a realistic time-to-impact. These trajectories are not as realistic as computed using full aero, launch tables, and numerical integration, however. This mover is most often used on a rocket, artillery, or mortar platform definition, fired from a launcher configured with a WSF_FIRES_LAUNCH_COMPUTER and associated fires_tables.

Commands

remove_on_impact <boolean-value>

Defines whether to remove the launched platform on impact and terminate any active weapon engagement.

Default: true

use_simple_propagation <boolean-value>

Defines whether to use a simple parabolic trajectory, using only values of maximum_height and time_of_flight.

Default: false

constrain_to_simple_propagation <boolean-value>

In the case where a solution cannot be computed for the given values of range, max. height, and time of flight, use the solution given by the use_simple_propagation option.

Default: false; the mover will relax the condition on max. height instead, in order to compute a solution.

Trajectory Commands

Note

Usually, one uses a fires_table, along with dynamically firing the weapon during the simulation, to specify specific trajectories. However, one may manually configure the mover with these commands.

impact_range <length-value>

Defines the range from the launching platform where the munition will detonate.

initial_bearing <angle-value>

Defines the bearing from the launch platform that the munition will travel in its trajectory.

impact_location <string-value><latitude-value><longitude-value><length-value>

Specifies an impact location using a geo point reference. For example:

impact_location geo-point-tag 38n 90w 100 ft // altitude

time_of_flight <time-value>

Specifies the time of flight of the munition.

maximum_height <length-value>

maximum_ordiante <length-value>

Specifies the maximum height the munition will attain in its trajectory.
