Scratch

xosmallfryox: please post your question on one of the other forums. Thanks.

thx for helping me out with my games  . by the way here's the code to make a character jump.<when green flag clicked><forever><repeat until><touching color[ black] <change y by( -4)
then make a black platform at the bottom of the screen.

mahsheed, please ask new questions in new threads, rather than hijacking an existing thread.

Your question belongs on the "All about scratch" forum.

how do you put in multiple costumes at once

how do i make my sprite move like right or left up or down when i press thous arrow
keys?

Vali, do [blocks]<move(  )steps>[/blocks] (positive number) for right and[blocks] <move(  )steps>[/blocks] (negative) for left.

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?

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.

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:

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.

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.

how do you make a platform game with the gravity?
