Bool

[boriel]

Code:

DIM ar(23, 3) as Ubyte ' 24 x 32 bits.

just curious, (in case I want to make an array of a different size)
how does 23,3 translate into 24,32

The array goes from 0 to 23 (24 rows) and from 0 to 3 (4 bytes = 32bits). So you have 24 x 32bits (1 bit per screen cell).

Code:

IF GetBool(ar, 3, 20) THEN
...
END IF

so the numbers 3,20 correspond to my screen co-ordinates?

thanks for the help

Yep, the are screen coordinates, and ar your byte array.
