 Before we start with the tutorial I have to admit that I (Geo-Magician) am merely the poet of this tutorial. The Earwigo software itself was written by Nick (aka sTeamTraen). He came up with the idea and he has written the entire program (with the help of many individuals from all around the world ;-) ).  Before we start with the tutorial I have to admit that I (Geo-Magician) am merely the poet of this tutorial.

 +If you want to work with the latest version of the tutorial it is currently best to download the {{:create_your_first_cartridge:earwigo_tutorial_081.pdf|pdf version of the tutorial}}. It contains some yellow markings that will help me to find my way around but it should not disturb you to much.

 +Wherigo Players will not display all image formats. The safest way is to stick to jpg images.

 +  - Make sure that the images are .jpg or .jpeg and NOT .png
 +  - Use an application to remove all EXIF (Exchangeable Image File Format) data from photos and pcitures

 You might be wondering why we have not used the more convenient Wherigo command: “Show_a_screen Zone:Start”. Good thinking but due to a Garmin bug this is not a good idea. Since we want to keep our cartridge usable for all players we have used a slightly different approach to ensure the cartridge will work on all devices. You might be wondering why we have not used the more convenient Wherigo command: “Show_a_screen Zone:Start”.

-Only one Show_a_screen command is save to be used on all devices. It is the command “Show_a_screen Standard_screen:Main”. This command will show the home or main menu page. The home page will not directly guide the human player back to the starting position but we can point him towards it with a little extra work. The idea is to present a message with instructions followed by the “Show_a_screen Standard:Main” command. If you have a look at the “ToLateToTalk” message you can see that we have already provided the required extra information for the human player. All we need to do now is to present the main menu and hope that the player can find the described page (they typically do ;-)+Only one Show_a_screen command is safe to be used on all devices.

 Item 6 on the ToDo list is to enable the Zone "Tree". I know that you can enable Zones by now ( Set_value Zone:Tree:Active => true) but this time we have to remember a condition. We have started the last 5 sections of this tutorial because we need to built an IF ELSE EndIF Statement.

-You might be curious why I am using a command and a message to display this information. The item description looks like a much easier way to do this without all the trouble of creating commands and messages. This is actually a good question and if you have really asked yourself something along this line I think you are ready to put your own cartridges out there ;-). Coming back to the question: the item description is created together with the item itself when the cartridge is started for the first time. At this time the cartridge is still incomplete and there is no completion code available. If you display a message however this will look up the current value of any variable (for example Player.CompletionCode) and display it to the human player.+You might be curious why I am using a command and a message to display this information.

 +=== Testing the "Completion Code" ===
 +The emulator and the test compilations will not have a working completion code in it. You will see a dummy code "completion code".
 +
 +This is the theory behind it: The completion code is connected to the human's GS player account and can only be used by this account. If you get the code from someone else, you can not mark a cartridge as completed. The test run and compilations will not create a valid useable code.
 +
 +Should you really desire to see a working completion code, this is how to get there:
 +  - Upload the cartridge to GS www.wherigo.com
 +  - Secretly publish the cartridge (invisible, not referenced in search engine)
 +  - Download this published cartridge with your own GS player account
 +
 +If you run the resulting *.gwc in the emulator things should work out as expected (I would not really do this because I have done it once and I now believe that it works. ;-)
