Nice, good work, man...
O.O so big...
Nicely done!
oooo its so big
I have used your scrolling idea to make a scrolling starfield for my next game. See the demo here... (link to project)
hmm i can't even see any flaws in putting the big picture together - its very well done
nice scrolling
thanks for sharing this Jens, I am going to use your method in the sequal to the Guardian. I'll be sure to mention you in the credits.
great project
Incredibly good effect. I like it.
kwl
that also didn't work for me put ill download yours
The trick is that the 'big picture' is really made up of four smaller ones, of which none is bigger than the playfield.
how did you get it to upload cause when i try that it shrinks please tell me
Cool
Thanks.
Err, it's one that came with my camera, called ArcSoft or something. But you can also use freeware (I recommend irfan view http://www.irfanview.de wich in fact is a lot better).
Yes, almost. What computer software did you use?
Hi Greatdane. I chopped up the 'big' picture with an external image processing software, in which I could define the exact dimensions of a selection area. If you look closely at the scripts you'll also notice that the project does *not* scroll throughout the whole area of the composite picture, but instead observes some kind of padding. This is because I found out that you cannot move a sprite completely off-playfield, but have to let some part of it within. Does that answer your question?
Jens? This looks very nice, I've seen all these scripts and how they work, the only thing wrong is that how do you seperate a picture into four parts and know each one is the size of the scratch playfield?
sweet
Curses - the principal works, but obviously it always rotates around the centre of the map, not around the centre of the screen. Still, if the offset geometry could be worked out...
Combine that with My Red Neptunes idea... hmm.
I just realised somethign really cool... because your scrolling system has the centre of rotation of each sprite in teh same place, you can rotate the larger picture - something that is not possible in other, multi-tile scrolling systems. Could be the basis of a really nice driving/flying game...
You can accually have a sprite or a background that is bigger thanth playfield without any scrolling. It's a trick I've learned yesterday. Right-click on the background and select "Grab screen region for new sprite". Now here goes the tricky part. grab a region of the background within the playfield and, still holding the mouse, drag it beyond the borders of the screen. What you get is a giant sprite of the scratch screen, now you can edit it, delete, etc.
actually the zoomed size is the original, pressing the button reduces the size of the four tiles to let them appear as one single picture using the whole stage. Scrolling moves each of the four tiles, that's the trick.
isn't the zoom feature just increasing the size of the picture? And the scrolling is just moving the picture a bit?
Nice project!, Please check out some of mine by clicking on my icon!
wowo that is nice love it it shows your personality
Wooooowwwww !!! impresionante :), me gusta Jens it´s very nice, Maybe I´ll use this tip for a comming project, very usefull, nice
wow!very creative!
la la la
Oh,ok.
realy n!ce
mumzie2, I don't know if it's Cupid, but I don't think so, because Cupid usually wouldn't be depicted playing a musical instrument, but rather shooting arrows of love. This is just a picture I took in the town of Pezenas in Southern France, because I liked the motive of the 'Band'.
Is that Cupid?
OMG! This is amazing!
thats is so cool
I'm Guessing you couldn't have sprites on this? OR they wouldn't move with it. right?
cool
Cool!
forest, the (simple) trick behind this project is to cut up a big picture into four smaller ones, each the size of the Scratch playfield, and then to set the rotation center of each partial image to the center of the 'big' picture, i.e. into the very corner of the smaller tile. This last step is not obvious if you have a look at the source code, since you have to define it in the Scratch drawing editor.
everything you do seems amazing.. but when i tried to adapt the image to another i hit some problems.. I have been experimenting with frame by frame animation and i just wondered if there was a way of batch inputting images into scratch to make that kind of animation easier..
wow that could be useful! But nit for a drawing game, because pen isnt very.. eh.. it goes away.
It's amazing that's possible. I've downloaded your project and will examine the scripts to see how you did it. The Scratch playfield always seemed to set an absolute boundary. Thanks!
nice!
