Re: Question on variables
<when green flag clicked>First of all I only know how to do it with global variables, but anyways: If you havent changed the names of the costumes, they should be like "costume1", "costume2", etc:
so you can clearly see the Costume #. Next, there is a little block in Looks ( I think the type of block is a reporter)that says Costume #.
So here is an example of the blocks you'd need for an alien game or something where every time you hit a spacecraft you get 10 pts. This would be a script for the spacecraft, which would have 2 costumes, a regular costume and a blown-up one:
[blocks]<when green flag clicked>[/blocks]
[blocks],<if><<(costume # <=> 2 )[/blocks]
[blocks]<change{variable}by( 10[/blocks]
[blocks]<end>[/blocks]
(This MAY not look good, it's my 1st time using blocks in the forum.)
You get the idea. When green flag clicked, if costume # = 2, change score by 10.
Which means:if it is in its blown-up costume, you get 10 pts.
Hope this helps!

Re: Question on variables
Wait... Why does it say "when green flag clicked" at the beginning of my last post...
I never put one there!

Re: Question on variables
Variables are Scratch's way of remembering different numbers, digits, values or key combos for a while. Basically, if you set variable A to on, then it'll stay as "on" until it is changed. This is useful for C blocks (like If ___), and making Scratch be able to ask multiple questions, and save answers to all those questions, not just the first one.

Re: Question on variables
A variable is just what it sounds like. It varies. 
For the example, let's name the variable "Score."
Let's pretend that you are making a maze game. Whenever you get to the next level, you want to get 10 points.
You do this:
change [score v] by (1)The possibilities for using variables are infinite. What I would recommend is to look at the example projects that use variables and look at how they use them.

Re: Question on variables
Hello, I am still new to Scratch. In Tech class, we have to create a game called "MadLibs."
I am not sure if we are able to put the variables in places that suits us best. For example, I have some 'fill-ins' that I want the variables to stay in place. But, whenever I open this game the next day, the variables will be out of place.
This is the game: http://scratch.mit.edu/projects/Cheese-Dragon/2494777
It is not finished. Thanks for hearing me out. And if you can help, thank you very much!

Re: Question on variables
well if your making a game you think this,
<scratchblocks>
when gf clicked
forever
wait until <touching [? v]>
change [lives v] by [-1]
end
</scratchblocks>
no its like this.
when gf clicked
forever
wait until <touching [? v]>
change [lives v] by [-1]
repeat (5) times
show
wait (.2)
hide
end
when gf clicked
wait until <(lives) = (0)
hide
stop all
variables are bridges that connect scripts.

Re: Question on variables
Forgive me if this has been answered already, I'm new Scratch and to this site.
I know you can get variables to stay where you've put them if you make them visible. The problem is they then show up on the opening screen. Please can someone tell me if there is a way round this?
