Part V:

The ColumnMapping property of the DataColumn class lets you customize the output even more. This property is a MappingType enumerated value that can be Element (the default), Attribute (the column is mapped to an XmlAttribute node), SimpleCon tent (the column is mapped to an XmlText node), or Hidden (the column doesn t appear in the XML output). For example, consider this code:

Set the ColumnMapping property for some columns. With ds.Tables( Publishers ) .Columns( pub_id ).ColumnMapping = MappingType.Attribute .Columns( country ).ColumnMapping = MappingType.Hidden End With

This is pure AI. These statements are doing exactly what you would do if you were steering a tangerine towards the bread. They work on the principle that if the bread was to the left of you, you d move left. If the bread was below you, you d move down, and so on. If this code is placed in the Update method, the tangerines try to head towards the bread. The speed of the tangerine has been set so that the tangerines move quite slowly, but it definitely feels like they are chasing you. If you really want to scare the player, you can speed the tangerines up. Figure 15-5 shows the situation in the game a few seconds after the tangerines have been made to appear. This is actually quite a scary point in the game, as the pepper is also deadly. If you want to make tangerines that ran away from the bread bat (to make a kind of chasing game), you just have to reverse this behavior.

This is the XML text produced for a row in the Publishers table:

<Publishers pub_id="0736"> <pub_name>New Book Books</pub_name> <city>Boston</city> <state>MA</state> </Publishers>

The GetXml method returns the XML that you would write to disk with the WriteXml method:

Dim xml As String = ds.GetXml()

The only problem with the tangerines is that we can t really have them make the player lose a life when they touch the bread bat. This would be very unfair because the player would almost certainly die quickly. We get your younger brother to test this form of the game play and see how long he can survive and the answer is what we expected not very long. However, we can arrange things so that the player suffers in other ways. Every killer sprite that hits the player s bat could cost them 10 points, whereas every one they manage to get rid of by hitting it with the cheese could earn them 10 points. This makes the killer sprite a bit like the pepper in some respects. The final Update behavior for the KillerTangerine looks like this:

The only relevant difference in the output produced by the WriteXml method is that GetXml doesn t produce the < xml> processing instruction at the beginning of the XML text.

Unlike the GetXml method, all the overloaded versions of WriteXml take an additional (optional) XmlWriteMode argument, which can be one of the following values: IgnoreSchema (default, doesn t write the schema), WriteSchema (writes the schema and the table data), or DiffGram (writes the current contents of the DataSet but preserves infor mation about rows that were modified since the most recent AcceptChanges method).

Troubleshooting The yellow handle appears only if the line is long enough to support it. If you do not see the yellow handle, drag the oval slightly up or to the right to lengthen the connector line.

For example, the following statement produces an XML file that contains both the DataSet data and its schema:

ds.WriteXml( ds.xml", XmlWriteMode.WriteSchema)

public override void Update(BreadAndCheeseGame game) { if (game.GetScore() > killerTriggerScore) { // Score has passed a threshold. // Turn the killer sprite on and move the threshold. isDeadly = true; killerTriggerScore = killerTriggerScore + killerScoreStep; }

This is a condensed version of the resultant file. (I added a blank line between the schema and the data section.)
