Arrays of sprites and pp256

[na_th_an]

As I wrote recently, that depends on whether the resulting number of multiplying width by height is odd or even.

If it is odd, say for example "7", you have 7\2 = 3, but with 3 integers you can only store 6 bytes. You need an extra integer.

The correct expression would be:

Code:

Dimmension% = CEIL(( Width% * Height%) / 2) + 1

But the CEIL (round up) command doesn't exist in QB, so the golden rule is add 1 if w*h is even or 2 if w*h is odd.

Anyhow, if you use sprites with sizes that are powers of two, the result is always even.

I've said this tons of times: use sizes that are powers of two: the calculations are faster.
