Create World


1. World Image. The image or icon displayed to all world members for this world. If using an icon, a tap here will pull up the world profile section for customization.

2. Take Picture. A tap here will pull up the default Android camera application and by taking a picture, it will be used as the world image.

3. Select Image. A tap here will pull up the default Android image gallery application where a image may be selected as the world image.

4. Use Icon. A tap here will remove any image used as the world image and instead use an icon. This icon may be customized by a tap on the world image.

5. World Name. Enter the name of the world here. This is how the world will be seen by all members. Note once a world name is selected, it cannot be changed.

6. Domain Name or IP Address. Enter the DNS (Domain Name) or the IP Address of the world. Note that this is a critical field as this is how the device hosting the world is discoverable by devices hosting Galixsys Communicator. For more details on how to configure Galixsys Hub for Internet usage, please see the section Internet Configuration.

Taping here is different than other fields in that if a domain name is not entered, and another tap is performed, the public IP address of the device will be shown. If this is kept and the world created, the device will be publicly available (assuming all ports are forwarded in the gateway and HTTP traffic is allowed to enter the network – please see Internet Configuration for details). If the public IP address is tapped, the local IP Address will be shown. If this is selected, the world is only usable locally (i.e., on “192.168.x.x”) and will not function correctly even if the ports are opened in the network gateway. This is a “Test” mode, and will be indicated as such on the Information screen (“Test Mode” Yes). Another tap on the local IP Address will send the user back to allowing a Domain Name to be entered. This is a repeating circle of DNS Entry → Global IP Address → Local IP Address, of which only the DNS Entry may be entered by the user (the IP Addresses are automatically gathered).

Note that this is perhaps the most important field for the user to configure, as how the device is to be addressed (via DNS, via fixed public IP Address, via local IP Address) has significant impact to how members may access the World and connect to other members. If the World is to be active for any significant amount of time, it is STRONGLY recommended to use a domain name by registering via a domain name service as the public IP Address on most home networks WILL change over time. In this case, all members would need to update their IP Address in order to access the World. A domain name solves this problem (i.e., public IP Address changing) and several free options exist.

7. Base Port. Enter the base port number of the world. Galixsys Hub requires the use the base port + the next four ports to be open (i.e., a base port of 50500 will use 50500, 50501, 50502, 50503) in order to operate. If the network that the device hosting Galixsys Hub is on has a firewall (the home router provided by most ISPs do), these ports must be opened if the device hosting Galixsys Hub will be visible to the Internet at large. For more details on how to configure Galixsys Hub for Internet usage, please see the section Internet Configuration.

8. World Location. Enter the world’s location here. This can be the actual location, or a fictional one, as it is a simple string and not used anywhere other than to provide some color for the world.

9. World Description. A single sentence to describe the world. This is shown to all world members as a subtitle under the world name to provide further color to what the world is about.

10. Crypto Seed. Enter a string that will be used as a seed to generate the encryption keys used for all data transport. By default, all user-generated messages and data sent encrypted over HTTP. If this field is left blank, all messages will be sent un-encrypted (clear text with no encryption).
