Abstract

Methods and systems for controlling vehicles within graphically simulated environments are described herein. A video game such as a vehicle-based combat game may have vehicles (such as airplanes) operating in a simulated three dimensional space. In a destination based control mode, users may partially control vehicles using two-dimensional input devices by inputting a new destination for the vehicle to go to, and the game'"'"'s control logic may then automatically calculate how to control the vehicle toward the new heading. Fight and assault (bombing) control sub-modes may be provided. In addition, in an immediate control mode, a user may provide input that indicates a direction and speed of rotation, to provide more direct control of a vehicles control systems and/or control surfaces.

Claims

1. One or more tangible computer readable media storing computer readable instructions that, when executed by a data processing device, cause a system to perform:

graphically rendering a virtual environment using a physics engine;

simulating a vehicle within the virtual environment using the physics engine;

while maintaining the vehicle in a first directional heading, receiving user input identifying a second directional heading;

pivoting a camera angle about the vehicle to the second directional heading;

causing the vehicle to alter course from the first directional heading to the second directional heading; and

maintaining the camera angle at the second directional heading while graphically rendering rotation of the vehicle as the vehicle alters course to the second directional heading.

2. The computer readable media of claim 1, wherein causing the vehicle to alter course comprises:

determining one or more inputs to apply to one or more corresponding control systems of the vehicle to yield the desired second directional heading;

applying the determined one or more inputs to the one or more corresponding control systems; and

using the physics engine to determine a resultant effect of the inputs on each corresponding control system.

3. The computer readable media of claim 2, wherein the one or more control systems comprise flaps and ailerons.

4. The computer readable media of claim 2, wherein the one or more control systems comprises an engine power of the vehicle.

5. The computer readable media of claim 1, wherein the instructions further cause the system to perform:

providing a first vehicular control sub-mode, wherein a default camera angle of the first vehicular control sub-mode provides a view from behind and above the vehicle being controlled, wherein the first vehicular control sub-mode provides a first targeting reticle associated with a first weapon attached to the vehicle; and

providing a second vehicular control sub-mode, wherein a default camera angle of the second vehicular control sub-mode provides a view from behind and below the vehicle being controlled, and wherein the second vehicular control sub-mode provides the first targeting reticle associated with the first weapon attached to the vehicle, and concurrently provides a second targeting reticle associated with a second weapon attached to the vehicle.

6. The computer readable media of claim 5, wherein the vehicle is an airplane, the first weapon is an air-to-air weapon, and the second weapon is an air-to-ground weapon.

7. The computer readable media of claim 5, wherein the instructions further cause the system to perform:

when in the second vehicular sub-mode, maintaining a target window on a ground-based target after deployment by the vehicle of an air-to-ground weapon until the air-to-ground weapon hits the target or the ground in the virtual environment.

8. A method comprising:

graphically rendering a virtual environment for output to a display screen using a physics engine executing on a computing device;

simulating a vehicle within the virtual environment using the physics engine;

while maintaining the vehicle in a first directional heading, receiving user input identifying a second directional heading;

pivoting a camera angle about the vehicle to the second directional heading;

causing the vehicle to alter course from the first directional heading to the second directional heading; and

maintaining the camera angle at the second directional heading while graphically rendering rotation of the vehicle as the vehicle alters course to the second directional heading.

9. The method of claim 8, wherein causing the vehicle to alter course comprises:

determining one or more inputs to apply to one or more corresponding control systems of the vehicle to yield the desired second directional heading;

applying the determined one or more inputs to the one or more corresponding control systems; and

using the physics engine to determine a resultant effect of the inputs on each corresponding control system.

11. The method of claim 9, wherein the one or more control systems comprises an engine power of the vehicle.

12. The method of claim 8, further comprising:

providing a first vehicular control sub-mode, wherein a default camera angle of the first vehicular control sub-mode provides a view from behind and above the vehicle being controlled, wherein the first vehicular control sub-mode provides a first targeting reticle associated with a first weapon attached to the vehicle; and

13. The method of claim 12, wherein the vehicle is an airplane, the first weapon is an air-to-air weapon, and the second weapon is an air-to-ground weapon.

14. The method of claim 12, further comprising:
