$world->path
str is a string defining a path. The following example shows the features of paths:
3n2e4n2e{ne}e{open door}3n
The general syntax syntax is "<number of repetitions><command>". "<number of repetitions>" can be omitted, in this case it is considered as 1. command is the command that will be repeated. If it is not a one-letter command, it should be enclosed in braces ({}).
The example above would generate these commands:
n n n e e n n n n e e ne e open door n n n
The commands are send using the settings in the Sending tab of the Preferences dialog (see Section 5.2).
