Abstract

Systems and methods of virtual world interaction, operation, implementation, instantiation, creation, and other functions related to virtual worlds (note that where the term “virtual world” is used herein, it is to be understood as referring to virtual world systems, virtual environments reflecting real, simulated, fantasy, or other structures, and includes information systems that utilize interaction within a 3D environment). Various embodiments facilitate interoperation between and within virtual worlds, and may provide consistent structures for operating virtual worlds. The disclosed embodiments may further enable individuals to build new virtual worlds within a framework, and allow third party users to better interact with those worlds.

Claims

1. A computing system comprising:

one or more processors; and

a non-transitory computer-readable media comprising instructions that, when executed by the one or more processors, cause the computing system to;

maintain, on the computer-readable media, a hierarchical representation of a plurality of nodes associated with a corresponding plurality of objects in a virtual space, the hierarchical representation indicating hierarchical relationships between respective nodes, wherein at least some of the plurality of objects are associated with respective executable scripts, and wherein a first node having a higher position in the hierarchical representation than a second node in the hierarchical representation is associated with a first executable script;

determine a modification permission for the first executable script, the modification permission obtained from a data structure associated with a second object associated with the second node in the hierarchical representation, wherein the modification permission indicates whether the first executable script is permitted to modify the second object; and

execute the first executable script in accordance with the determined modification permission.

2. The computing system of claim 1, wherein the hierarchical representation of the plurality of nodes is associated with a document object model.

3. The computing system of claim 1, wherein the first executable script is maintained as a sub-element of the first object in the hierarchical representation.

4. The computing system of claim 1, further comprising enabling the first executable script to invoke a second executable script associated with a third object associated with a third node in the hierarchical representation,

whereby the first executable script may indirectly modify the third object through invocation of the second executable script.

5. The computing system of claim 4, wherein the first executable script invokes the second executable script by executing a function naming an action identifier associated with the second executable script.

6. The computing system of claim 4, wherein enabling the first executable script to invoke the second executable script is conditioned on successful transmission of the second executable script to the third object.

7. A device comprising:

a storage device storing data defining a hierarchical representation of a plurality of nodes associated with a corresponding plurality of objects in a virtual space, the hierarchical representation indicating relationships between respective nodes, wherein at least some of the plurality of objects are associated with respective executable scripts, and wherein a first node having a higher position in the hierarchical representation than a second node in the hierarchical representation is associated with a first executable script;

one or more computer processor configured to execute software modules including at least;

an object modification module configured to determine a modification permission for the first executable script, the modification permission derived from a data structure associated with a second object associated with the second node in the hierarchical representation, wherein the modification permission indicates whether the first executable script is permitted to modify the second object; and

a script execution module configured to execute the first executable script on one or more computer processors in communication with the computer-readable media based on the determined modification permission.

8. A computing system comprising:

one or more processors; and

a non-transitory computer-readable media comprising instructions that, when executed by the one or more processors, cause the computing system to;

maintain, on the computer-readable media, a hierarchical representation of a plurality of nodes associated with a corresponding plurality of objects in a virtual space, the hierarchical representation indicating hierarchical relationships between respective nodes, wherein at least some of the plurality of objects are associated with respective executable scripts, and wherein a first node having a higher position in the hierarchical representation than a second node in the hierarchical representation is associated with a first executable script;

receive a request to execute the first executable script from an electronic device;

determine a modification permission for the first executable script, the modification permission based on a data structure associated with a second object associated with the second node in the hierarchical representation, wherein the modification permission indicates whether the first executable script is permitted to modify the second object; and

transmit the modification permission to the electronic device.

9. The computing system of claim 8, wherein the hierarchical representation of the plurality of nodes is associated with a document object model.

10. The computing system of claim 8, wherein the first executable script is maintained as a sub-element of the first object in the hierarchical representation.

11. The computing system of claim 8, further comprising determining a second modification permission for the first executable script, the second modification permission associated with a second executable script associated with a third object associated with a third node in the hierarchical representation, whereby the first executable script may indirectly modify the third object through invocation of the second executable script.

12. The computing system of claim 11, wherein the first executable script invokes the second executable script by executing a function naming an action identifier associated with the second executable script.

13. The computing system of claim 11, wherein said determining is based on receiving a value indicating successful transmission of the second executable script to the third object.
