Title: 16*16 Images
Post by: Munchor on November 21, 2010, 03:13:43 pm: Hey, I was trying to implement an image in my programs, a 16*16 image, this is the code:

Code: [Select]
00000000000000000000000003F80404080410027FFF8001FFFF781E4812300C
So I would have:

Code: [Select]
Lbl 1 [00000000000000000000000003F80404080410027FFF8001FFFF781E4812300C->Pic1 Pt-Change(0,0,Pic1 DispGraph Repeat getKey->Z If Z>=1 Goto1
However, nothing appears, is it a temporary problem or it works for you?

I gotta try it in WabbitEmu but I can't now :S

Code: [Select]
Lbl 1 [00000000000000000000000003F80404080410027FFF8001FFFF781E4812300C->Pic1 Pt-Change(0,0,Pic1 Pt-Change(8,0,Pic1+8 Pt-Change(0,8,Pic1+16 Pt-Change(8,8,Pic1+24 DispGraph Repeat getKey->Z If Z>=1 Goto1

Pt-Change(0,0,Pic1 Pt-Change(8,0,Pic1+8 Pt-Change(0,8,Pic1+16 Pt-Change(8,8,Pic1+24
Wuuuh thanks much! Like your reply ;)

Optimization ;)

Code: [Select]
Pt-Change(0,,Pic1 Pt-Change(8,0,Pic1+8 Pt-Change(0,8,Pic1+16 Pt-Change(8,,Pic1+24

Pt-Change(0,0,Pic1 Pt-Change(8,0,Pic1+8 Pt-Change(0,8,Pic1+16 Pt-Change(8,8,Pic1+24
Didn't work :S

Code: [Select]
Pt-Change(0,,Pic1 Pt-Change(8,0,Pic1+8 Pt-Change(0,8,Pic1+16 Pt-Change(8,,Pic1+24
Nice optimization, gotta try it too :)

What doesn't work is the image :S It is all confused and crazy :s

And I'm using Pause 9999

Post by: Deep Toaster on November 21, 2010, 04:13:09 pm: That's because your image is a 16x16 sprite. What you need to do is split it into four 8x8 sprites, and it should work.

Just a note, there's no reason to stop at 4 digits. You know you can pause for values up to 65535 (actually up to 65536, which is what 0 does)

is this: Say you have a picture like this:

■■■■■■■■■■■■■■■■ ■■▢▢▢▢▢▢▢▢▢▢▢▢■■ ■▢■▢▢▢▢▢▢▢▢▢▢■▢■ ■▢▢■▢▢▢▢▢▢▢▢■▢▢■ ■▢▢▢■▢▢▢▢▢▢■▢▢▢■ ■▢▢▢▢■▢▢▢▢■▢▢▢▢■ ■▢▢▢▢▢■▢▢■▢▢▢▢▢■ ■▢▢▢▢▢▢■■▢▢▢▢▢▢■ ■▢▢▢▢▢▢■■▢▢▢▢▢▢■ ■▢▢▢▢▢■▢▢■▢▢▢▢▢■ ■▢▢▢▢■▢▢▢▢■▢▢▢▢■ ■▢▢▢■▢▢▢▢▢▢■▢▢▢■ ■▢▢■▢▢▢▢▢▢▢▢■▢▢■ ■▢■▢▢▢▢▢▢▢▢▢▢■▢■ ■■▢▢▢▢▢▢▢▢▢▢▢▢■■ ■■■■■■■■■■■■■■■■

Instead of storing it as a 16x16 picture, as in

Code: (Axe) [Select]
:[FFFFC003A0059009881184218241818181818241842188119009A005C003FFFF]→Pic1
you should think of it as four 8x8 pictures:

■■■■■■■■ ■■■■■■■■ ■■▢▢▢▢▢▢ ▢▢▢▢▢▢■■ ■▢■▢▢▢▢▢ ▢▢▢▢▢■▢■ ■▢▢■▢▢▢▢ ▢▢▢▢■▢▢■ ■▢▢▢■▢▢▢ ▢▢▢■▢▢▢■ ■▢▢▢▢■▢▢ ▢▢■▢▢▢▢■ ■▢▢▢▢▢■▢ ▢■▢▢▢▢▢■ ■▢▢▢▢▢▢■ ■▢▢▢▢▢▢■ ■▢▢▢▢▢▢■ ■▢▢▢▢▢▢■ ■▢▢▢▢▢■▢ ▢■▢▢▢▢▢■ ■▢▢▢▢■▢▢ ▢▢■▢▢▢▢■ ■▢▢▢■▢▢▢ ▢▢▢■▢▢▢■ ■▢▢■▢▢▢▢ ▢▢▢▢■▢▢■ ■▢■▢▢▢▢▢ ▢▢▢▢▢■▢■ ■■▢▢▢▢▢▢ ▢▢▢▢▢▢■■ ■■■■■■■■ ■■■■■■■■

Then you'd store each 8x8 chunk one by one, starting with the top left, then top right, then bottom left and right. So you'd store it as

Code: (Axe) [Select]
:[FFC0A09088848281]→Pic1 :[FF03050911214181] :[8182848890A0C0FF] :[81412111090503FF]
which is basically the four 8x8 sprites one after another, and it should work.

Ooooh thanks, then I gotta split my image, it won't be hard using tokens :)
