Working Out Pixels - Amos

[WAKD]

I`m still on an early path to learning code so, I appreciate any help and patience. I`m trying to set up zones for four buttons. I`ve tried everything and I think the main problem I have is I cannot figure out where the pixels are when it comes to drawing boxes or setting zones.

What is the easiest way to plot out where the pixels are so that the zones will be reserved without given an error such as Illegal Function Call please?

By default a screen number 0 with 16 colors and 320x200 is open by Amos.
The upper left point is (0,0) and the lower right corner is (319,199)
If you want to draw pixel, you can use "plot" (point) or "bar" (filled rectangle).
For example :
bar 100,100 to 200,150 : rem a rectangle of 100 pix wide and 50 pixels height

By the way, the zone commands have some bugs and sometimes defined zone throws some exception.

Don't know if it answers to your question.

If I can suggest something, it is to read carefully the manual, in particular the chapters about the screens and the graphics commands.

Bye

So, is it good practice to use the bob editor to create buttons to reserve zones for them or not?

Hmm don't know exactly what you mean :-)
Zones are used with bobs generally as visibility (display) zones : you don't want what that the bobs appears in some places in the screen.
Otherwise Amos zones are more dedicated for bitmap (which are not handled by blitter usually) to add collide properties.
What do you want to do in fact ? :-)

Well, you should use Bobs if you need them. With zones you can check if a bob has entered that specific zone and react to this event.

In your special case i had to say "No, not really!"
