I just discovered Bots Inc. and am trying to render some of the lessons within Etoys.
In Bots Incs. when you click on a Bot a balloon pop's up and when you enter text and hit <return> the text you entered is executed. How can I execute a command (do it) on <return>?
Also, I have a script that on mouse over prints:
Im a Bot. My position is: 769.5@452.5 and my direction is:34.3357941965284
How do I print integers or specify that I only want 2 digits to the right of the decimal point? (Below is my script). script1 | tmpStr | tmpStr := 'Im a Bot.\My position is: ' withCRs , self getLocation printString , '\and my direction is:' withCRs , self getHeading printString. self sayText: tmpStr
Thanks, Stephen

Subbu,
Thanks it did help, I got it to work, but I don't understand the following and not sure if it is a bug in Squeak or in my head. I ran the three commands below in a workspace and don't understand why the first one failed
Transcript show: 2.54343 printShowingDecimalPlaces: 2 - Failed Message Not Understood t2 := 2.54343 printShowingDecimalPlaces: 2 - OK Transcript show: t2 - OK showed 2.54 in Transcript

FYI, I have the same problem in Squeak 4.2 and Etoys 4.1
Also I noticed that if I use parentheses I can get it to work: Transcript show: (2.54343 printShowingDecimalPlaces: 2) - OK does not throw exception

That's it exactly. Without the parentheses, the Transcript thinks that you are trying to send it the message #show:printShowingDecimalPlaces: which it does not understand. By adding parentheses, you are first sending the message #printShowingDecimalPlaces: to 2.54343 (a Float object), which understands the message and answers a ByteString object. You are then sending the message #show: to the Transcript, which now understands that it should display the ByteString as you intended.
