I was just wondering, how would you hide a variable that is showing, but then show it later. For example, if you wanted to hide the health bars, until you click a button, then the health bars show.

That, is currently impossible in scratch. maybe you could ask for it in the next downloadable scratch.

Hiding/showing the on-screen variable displays (or altering them with scripts) has been requested often.  Currently, covering them as Kevin suggested is the best you can do.

If you are interested in Health "Bars", you will need to make those on your own.  It has been done by using the "pen" to paint a wide line, which you can remove with "Clear" from the Pen menu.  (Search the forums to find some examples).

Here is a demo of another possible way:

http://scratch.mit.edu/projects/EdnaC/81880

This is a "piece" of a project that I'm currently working on that stamps the health bars onto the screen.  To erase, this demo stamps again using the background color to avoid using "clear" (clear erases all stamps, and my project has some that I want to keep).  This may give you some ideas on possible ways to do what you want.

Thanks for your advice. I already made the health bars but I had a menu in teh beginning, so I wanted the health bars to show only when necessary. Thanks.

How do you make a sprite return to its starting position after gliding somewhere

How do I make a, lets say a bow and arrow, arrow come out of the bow and then make my guy move, but still be able to shot a arrow no mate were I am on the screen and see it on the screen

tell me if you need more detail

sirsnipes: in the corner ul see X and Y and wherever you move  your mouse it will change.
memorize the cordinates of the y and x and say <when green flag clicked>
                                                                         <go to x:(10)y:(10)>

    while on anothre script, <when green flag clicked>
                                       <glide(1  )secs to x   5 )y   5)>
                                       <glide( 1 )secs to x:(10  )y:(10)

to be shot? or to shoot? to be shot, this way makes it so you might die.

                Bow and arrow guy: <when[space]key pressed>
                                              <broadcast[ shoot ]>

               Arrow:    <when I receive[ shoot ]>
                            <point towards(human)>
                            <move(30)steps>
                            <forever if>  <touching[ human ]>
                             <broadcast[ DIE! ]>
                              <end>

                 Human: you can do the moving part. If you dont, look at my project "knight" and download.   <when I receive[ DIE! ]>
                       <switch to costume[ dead ]>
                       <stop all>

thank you so much for the help, i found out a lot when you showed me that, thank you, but i have one more thing to ask, sorry, but how do you keep it on the guy why he is moving around, like how do you keep the arrow on the "Bow and arrow guy" tell you shoot it, i know how to shoot it and all, but how do you keep it with him tell then, plz help

thank you so much,

switch to costume <costume#> - 1

I have got two question. With my posts of the masking the variables and the advice you gave me, its working great. Yet, when I post th project on the website, the "masker" is not "masking". Instead, its position has changed (it went lower). Also, I was adding music into my game. How would make it that when m is pressed, it would play music and then if n was pressed, it would play music but stop the other music that is playing.

okay. the arrow is a diferent sprite than the bow dude.
                                        Sprite arrow:<when green flag clicked>
                                                          <repeat until><key[space]pressed?>
                                                           <go to[ bow dude ]>
                   
                                           
                                    Bonus for not making him shoot again:

                                       bow dude script:
                                             <when[space]key pressed>
                                             <if> <<  <not>touching bow and arrow dude  >>
                                             <broadcast[dont shoot man]>
                                             <else>
                                               Do other script i told you
                                              <end>
                                     
                                Arrow script:
                                             <when I receive[ don't shoot man]>
                                             <set{anything}to(50)>

    The otehr script i told you:

                                <when I receive[ SHOOT]>
                                <if><( anything (variable) <=> (50 )>
                                <stop script>
                                 <else>
                                   do all that complicated stuff i told you.
                                 <end>

                         <when green flag clicked>
                         <set{anything}to(0)>
