Abstract

A method simulates the time effect of a battlefield engagement. The method determines whether a player is in an area of effects (27). A probability of kill is generated for the player (30). The player is assessed results of kill or near-miss (31-33). The method is repeated for a selected time duration (39).

Claims

1. A method for simulating temporal aspects of area weapons effects systems by a processor, the method comprising the steps of:

determining whether a player is within an area covered by an area weapons effect simulation;

generating a probability of kill for the player based upon player parameters and upon simulation parameters;

assessing results on the player based on the probability of kill; and

iterating the steps of determining, generating, and assessing, if a duration of the area weapons effect simulation is for more than one interval.

2. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 1, wherein there is further included the steps of:

receiving by the processor a mission message; and

storing the mission message in a last mission slot of a memory.

3. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 2, wherein there is further included the steps of:

determining whether the mission message indicates a time duration greater than one time interval;

determining whether there are any available mission slots in the memory;

adding the mission message to a list of active simulations, if there are available mission slots; and

overwriting an oldest mission message with the mission message, if there are no available mission slots.

4. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 3, wherein there is further included the steps of:

retrieving the player parameters which describe the player;

said step of determining whether the player is within the area covered by the area weapons effect simulation including the steps of;

determining a weapon/target type, if the player is within the area covered by the area weapons effect simulation; and

determining whether a duration of more than the one time interval is achieved.

5. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 4, wherein the step of determining the weapon/target type includes the steps of:

reading a weapon type from the mission message;

reading a fuzing type from the mission message; and

comparing the player parameters with the weapon type and the fuzing type to generate the probability of kill.

6. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 5, wherein there is further included the step of generating a random number.

7. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 6, wherein there is further included the steps of:

modifying the probability of kill to account for countermeasures taken by the player to produce an adjusted probability of kill; and

multiplying the random number by the adjusted probability of kill.

8. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 7, wherein there is further included the step of determining whether the adjusted probability of kill is greater than the probability of kill.

9. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 8, wherein there is further included the steps of, if the adjusted probability of kill is less than or equal to the probability of kill:

assessing the player a casualty;

canceling all mission messages; and

transmitting a message to the player to become inactive and wait for a reset.

10. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 8, wherein there is further included the step of assessing the player a near-miss.

11. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 8, wherein there is further included the step of determining whether the mission message indicates a duration greater than one interval of said area weapons effect simulation.

12. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 11, wherein there is further included steps of:

reading the time duration from the mission message; and

using the time duration from the mission message to determine whether the time duration is greater than one time interval.

13. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 11, wherein there is further included steps of:

reading a fire profile from the mission message; and

using the fire profile to vary determining the adjusted probability of kill.

14. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 11, wherein there is further included a step of decrementing an interval counter, if the mission message indicates a time duration greater than one time interval.

15. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 11, wherein there is further included a step of canceling the mission message, if the mission message indicates a duration of one interval.

16. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 15, wherein there is further included the step of determining whether any of mission messages are active.

17. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 16, wherein there is further included the steps of, if no mission messages are active:

waiting until an interval timer expires;

determining whether any of mission messages are active;

retrieving a next active mission message, if any mission message is active; and

iterating the steps of claims 3 through 16, if any mission message is active.

18. A method for simulating temporal aspects of area weapons effects systems as claimed in claim 16, wherein there is further included the steps of, if any mission messages is active:

retrieving a next active mission message; and

iterating the steps of claims 3 through 16.

19. In a battlefield simulation, a method for simulating temporal aspects of area weapons effects systems, the method controlled by a processor and comprising the steps of:

determining whether a player is within an area covered by an area weapons effect simulation;

generating a probability of kill for the player based upon player parameters and upon simulation parameters;

assessing results on the player based on the probability of kill and on countermeasures taken by the player; and

iterating the steps of determining, generating, and assessing, if a duration of the area weapons effect simulation is for more than one interval.

20. In a battlefield simulation, a method for simulating temporal aspects of area weapons effects systems, the method controlled by a processor and comprising the steps of:

receiving by the processor a mission message;

determining whether a player is within an area covered by an area weapons effect simulation;

generating a probability of kill for the player based upon player parameters and upon simulation parameters;

assessing results on the player based on the probability of kill and on countermeasures taken by the player; and

iterating the steps of determining, generating, and assessing, if a duration of the area weapons effect simulation is for more than one interval.
