Hi!

Is there any sort of sprite editor for 2d games?
Every time I try to import a BMP file I get a GET IMAGE error message claiming the image is too small etc..Whatever size I put it's always the same.
Is there any tutorial on this specific subject?

I would like to work with BMP and JPG files since I'm more skilled in that department then in AVI section..

Thx

It says "Bitmap too small to get image"?!

I mean..I have a 200x90 image and whatever values I put I get this stupid message.

Try this

load image "media\My.bmp",1
GET IMAGE 1, 0, 0, 199, 89

Do you still get an error?

'Try this

GET IMAGE 1, 0, 0, 199, 89'

if you load the bitmap as an image, you wont need to use 'GET IMAGE'. so what chopchop said kinda helped

I will try it and let u know..thx!
I'm a total newbie so everything's possible.
I'm working on am Animating Sprites Tutorial, so I might drop u some of its code here..

What I'm trying to do now is to determine what values should be entered in the GET IMAGE command when using BMP images containing more then one frame. I know this depends on the BMP inserted but I am yet to figure out what's the 'system' of entering those values.

For example:

LOAD BITMAP "d:\sprajtovi\character.bmp",1
FOR i=1 to 11
GET IMAGE i,(i-1)*102,0,i*102,90
NEXT i

This is from the tutorial. The "character.BMP" is a lot larger then these values would suggest. I tried doing the similar with my own BMPs but got the error message stated above...

Ok. I now fully understand the basics of GET IMAGE command, the image is being displayed BUT it colors look awful - all distorted.

How can I fix this? I'm saving the BMPs into 256 color mode.
I would like to know how can I make the background transparent on the existing image (I'm using PSP, Adobe, Paint..u name it) and would also like to figure out why are the colors so upside down when shown in Dark Basic..

I'm sure this was discussed like zillions of times but I couldn't find a topic on this specific subject.

Have you tried using 24 bit bitmaps instead?

Hi Tan!

I fixed the transparency problem. (figured it out by myself )
Hmmm..but when it comes to animated sprites it's sucha bitch to use those multy-frame BMP's...I wonder if me having a demo version of DB has anything to do with this inability to use GIF animations in "load bitmap" command?

I am aware of AVI file extension but I'm not sure if it is possible to make 2D games with AVI files being used as sprites?

LOAD BITMAP "d:\sprajtovi\character.bmp",1
FOR i=1 to 11
GET IMAGE i,(i-1)*102,0,i*102,90
NEXT i
the with of the bitmap must be atleast 11*102 by 90 or your get that error because when it tries to grab a image beyond the bitmap size, the bitmap is to small.
1122 is a really large bitmap, but thats what you need for 11 frames at 102 pixels per frame
whenever you use load image or get image add ,1 to the end of it to make it look clear.
load image "file",Image number,1
get image image number,x1,y1,x2,y2,1

GIF's are not available within DBPro - they currently require a hefty licence fee to Unisys, until the patent expires in June this year.

I believe (but am not totally sure) that AVI's can only be played to a bitmap - you could then use GET IMAGE on them, but it would be slow.

You can play an AVI directly to screen if you want (and place it where-ever you want on the screen). Look at the "play animation" command for the parameters.
