Re: Scratch Secrets: Tips and shortcuts

On the Mac, you can select a bunch of pictures in the Finder, then drag them onto the sprite pane to add them to the sprite's costumes.  I assume something similar works on Windows.

Re: Scratch Secrets: Tips and shortcuts

Hi DreamSchool,

I'm not sure if I understand your question. The only new block in the numbers category that I'm aware of is the math-function block. It lets your script perform a mathematical function for any number or variable. You can select the desired function using the block's drop-down menu. Did this answer help?

Re: Scratch Secrets: Tips and shortcuts

DreamSchool, I can understand your frustration about not knowing what the functions
   abs  (absolute value)
   sqrt (square root)
   sin (sine)
   cos (cosine)
   tan (tangent)
   asin (arcsine)
   acos (arccosine)
   atan (arctangent)
   ln (natural logarithm)
   log (log base 10)
   e^ (exponential)
   10^
mean.  The help screen could at least expand the abbreviations to the full names.

Unfortunately, even a moderately good partial explanation would take about a year (the high school course called trigonometry).

To get start, I suggest reading the Wikipedia articles on the functions (now that you have the full names) and the Wikipedia article on trigonometry.

Re: Scratch Secrets: Tips and shortcuts

For jumping, why don't you just make gravity, and then say change y position by(how high you want it to jump)

Re: Scratch Secrets: Tips and shortcuts

A "block" for gravity is suggested pretty often, but isn't something that would add value to the Scratch language.  Gravity could mean "accelerate in (negative) y" or it could mean "accelerate toward a planet".   I even did a project that has a sun orbiting a black hole, and the spaceships in the project are attracted to both.

Since "gravity" means different things to different programmers and projects, it is something you will have to implement on your own.  It really isn't that difficult though.

Some examples of Gravity's different "meanings" and ways to make it part of your project are in:

Re: Scratch Secrets: Tips and shortcuts

andy2290,

Ask your questions either on one of the threads by people who have requested questions to answer, or as a new thread in the "All about scratch" forum.  This thread is for rather well-hidden features of scratch, not for "how-to" advice.

Re: Scratch Secrets: Tips and shortcuts

Actually, the games are made on your own computer, in the Scratch program, then uploaded to the site.  If you go to the Home page, you will see a link to the Download area, where you can download the Scratch program.

Re: Scratch Secrets: Tips and shortcuts

this is how you can scroll

make a variable called Scroll X or whatever you wanna name it


then put this in a character

<when green flag clicked>

<forever>

<if>

<key[ right ]pressed?>

<change{ scrollX }by( 1



then  in the floor that you want to move put this


<when green flag clicked>

<forever>

<go to x sad   ((  <{ scrollX }>   <*>   -1   ))  )y sad  0



and for the floor beside of it repeat the same thing but put this for the X position

((    <{ scrollX }>    <+>   160  ((   <*>  -1  ))  ))
