No watch feauture in AI2 yet? No problem...

[Scott Ferguson]

Here some methods Scott uses for debugging his projects until a 'Watch' feature is available for AI2:

Screen1.Title to (join... |  variable) in a procedure can display and update the contents of one or more variables while the app is connected to the device or emulator.

Why do it this way?

So I don't have to change my screen layout by adding a label just to display the debug info.

When you remove the debug blocks, the original title will display.

This is useful until we get a watch option on our blocks in AI2.

Do It is another useful feature that can be used for testing and debugging.

I have created a procedure Normalize which should return a number in the range 0 <= degrees < 360.

I can test a call to this procedure using just a call block and number attached to the input socket.

Testing a value with Do It...

Viewing the result:

You can remove the comment after testing also or just delete the blocks.
