Questions on E-Toy Scripting of Alice (3-D)

[Scott Wallace]

Hi, Mark,

Drop some numeric-valued tile (such as, say, "WhiteRabbit's heading") 
into the TEST pane.  Because a TEST pane requires a boolean-valued 
expression, this will magically get expanded into a related 
boolean-valued expression -- in this case "WhiteRabbit's heading < 
5".   Now it should be straightforward to edit that into the 
expression you really want.
