Here's a list of tips and shortcuts from the Scratch programming team.

SPRITES
* Find a sprite: To show a sprite that's off the screen or hidden, Shift+click on its thumbnail in the sprite list (bottom right-corner of screen) - this will bring the sprite to the middle and show it.
- To turn a costume into a separate sprite, right-click (Mac Ctrl+click) and select "turn into a sprite".
- Drag the blue line on sprite thumbnail (in the middle of the screen) to rotate the sprite.
- To rotate a sprite from the stage, shift+click on the sprite.
- Shortcut to get a sprite to "point in direction 90": double-click on sprite thumbnail in the top middle of the screen.
- To delete a sprite, use the Scissors tool (or Right-click and choose "delete")
- To delete multiple sprites, Shift+click with the Scissors (it won't revert to the arrow)
-To make multiple copies of a sprite, Shift+click with the Copy tool (it won't revert to the arrow)
-Drag to reorder thumbnails in sprite list (bottom right corner of screen)
-Drag to reorder costumes in the Costume tab area
-To make a sprite that looks like part of the background, Right-click (Mac Ctrl+click) the stage to grab a portion of the image on the stage.

BLOCKS AND SCRIPTS
- To copy a stack of blocks from one sprite to another, drag the stack to the thumbnail of the other sprite (at the bottom right corner of the screen).
-To clean up the script area, right-click (Mac Ctrl+click) in Scripts area.
-Get help for any block: right-click (Mac Ctrl+click) on the block
- You can fit some blocks within other blocks. For example, you can put any Number or Sensing blocks with curved edges inside a "switch to costume" block or any block that has a white number or text area.
- Want to get the current x-y of a sprite? Click on the Motion category to update the x-y numbers in the glide and go-to blocks in the palette.

PAINT EDITOR
- To crop an image, outline it with the Selection tool, then Shift+delete (or Shift+backspace)
- To rotate part of a costume, use the selection tool, then click the left or right Rotate button (curved arrows).
- To rotate more precisely: Shift+click on the left or right Rotate button. It will let you enter a # of degrees to rotate
- Grow or shrink more precisely: Shift+click on the Grow or Shrink button (arrows pointing out or in). It will let you enter a % size for a costume
- To stamp multiple times, press Shift while using the Stamp tool.
- Press Shift with the Rectangle tool to make a square.
- Press Shift with the Oval tool to make a circle.
- Press Shift with Line tool to make a straight horizontal or vertical line.
- Press Shift key when clicking on a color square to change the other color.
- To pick up a color from outside the paint editor, select the Eyedropper tool, click in the Paint editor, then drag while holding down the mouse key.

REPORTERS & VARIABLES
- Check boxes to show monitors on stage
- Click a monitor to toggle between options (hide monitor name, show slider)

KEYBOARD SHORTCUTS (some of these are repeats with above)
-To delete multiple sprites, Shift+ click with the Scissors tool (it won't revert to the arrow).
- To make multiple copies of a sprite, Shift+click with Copy tool (it won't revert to the arrow).
- Ctrl+S to save your project.

OTHER
- You can drag multiple images at once into Scratch. They will become costumes within a sprite.
- You can drag in an animated GIF.
- You can drag in images from a web browser, Word, and some other programs (on Windows).
- You can drag in a Scratch project from a file folder.

I think I'm gonna explode.

Scratch can now use .MIDIs!

Does that mean a new version of Scratch came out! Ooh I gotta see!

Cool I never relised there was so many shortcuts

Yeah, hey. does anyone know how tomake a sprite jump and land on another sprite, like a piece of 'floating land'? i sprite is having throwing a fit and im getting spazzy.

The problem I have is that I have my 1023 possibilities divided into some 60 groups and there is nor range for these groups for example 1, 15, 17,.., 971 can be one group and 2, 4, 91, ... 287 another group.
so I want to say if
Case Board Count in(2, 4, 91, ..., 271)
  Do X
case Board Count in (1,15,, 17,...,971)
  Do Y
...
Wish full thinking;=>

Does anyone know how to make a sprite with a ghost effect stamp and stamp the ghost effect? For example, I can have code like this (the sprite is a small red circle):

[blocks]<set[ ghost ]effect to( 99 <go to x 0 )y 0<stamp>[/blocks]

and get the effect of this:

[blocks]<go to x 0 )y 0<stamp>[/blocks]


Notice how the ghost effect just disappears. Is there any way to keep it around? I desperately need this ability for a big project and I can't seem to get around it! Aaaaaahhhhhhhhh!!!!!

Everybody! This might be in the wrong place, but i guess it is also a secret!

Ok, no, you can't. You can however have a sprite over to create the ghost effect, but not while stamping (or what i do is create a black sprite, and set it's ghost effect to like 80 to make everything darker. You can use other colors though, Look at my Corridor thing).

All of a sudden, Scratch got easier.  Great tips!

add a wait block in there to make the animation move more slowly.

[b]If you have a bunch of isometric images in a rotation sequence, here is a greate tip[/b[

You can use a calculation to make your sprite look like its pointing in its direction, but it looks 3D! (   unfortunatly it isn't really 3D though...)


http://scratch.mit.edu/projects/NXTGeek/293561
http://scratch.mit.edu/projects/NXTGeek/360875

Its a lot easier to see in the first project.

1. Set your sprite so that it does not transfor the sprite to look like its pointing in its direction. It is that bottum of three buttons that are located below the open button and to the left of the mini representation of the sprites current image.

2. Import the animated .GIF of the rotation sequence.

3. Use the script in the shown project, it goes something like this:

S = custume_number
loop forever
{
switch_costume_to(direction*-1+90*S/360)
}

"S" being the number of costumes. See the projects fr exact scripts.

I hope this helps
