mouse input/movement by numpad PROBLEMS

[Agamemnus]

Whether they are blank or not doesn't matter. They are still there. So it's X times Y. If you're starting from 0 (and you are), then it's X times Y minus one.

And, you shouldn't use PSET....

Look at:

HELP: GET (Graphics) Statement Details

[axipher]

well then would it be
DIM char% (256) or (128), im not really sur

[Agamemnus]

X*Y.....

You're using GET and PUT statements..... in screen 13. Each % variable in QB uses 16 bits... each one in the array gives the palette color numeric value...

[axipher]

meaning...
yes, i am usnig GET & PUT statements, in SCREEN 13, but that still doesn't tell me wat number to use for a 16x16 sprite, i can draw it fine, its just saving it into the memory using DIM, GET, and PUT

[Dr_Davenstein]

You can use...

Code:

NumSprites * ((Width*Height)/2 +1)

I believe that was it anyway. It's been a while since I used QB.

[axipher]

so if its 16x16, then (16*16)/2 + 1 = 129

therefore DIM char% (129)???

The amount of bytes needed for a 16x16 8-bit image with 1 plane is:

width * height * Bpp * numplanes
16 * 16 * 1 * 1 = 256

There is a 4-byte PUT memoryheader, so the total amount of bytes needed is:

256+4=260

Since each integer is made up of 2 bytes, you need a total of

260/2 = 130 integers

Since in an array the subscript 0 counts too, you should define it indeed as

Code:

Dim Something(129) As Integer

[axipher]

well i got it my way and its faster, not like ill have more then 1 plane or anything, thnx anyway

[Agamemnus]

bah I didn't know what I woz talking about. :-|
