Scratch

I've run into a number of glitches that only appeared in the Java version online.  It's a tedious process to track them down but that's what you have to try to do.  The first step is to try and isolate the problem.   Copy your project into another project using Save As, then start removing pieces of the project to make the project smaller.  Every time you remove a piece, test the new, smaller project on Scratch and then upload it to the web.  Try to make the smallest project you can that shows the problem.  Using this process, you should be able to pinpoint exactly what is screwing up.  Then, you can either try to find a work-around (another way to code it that works in both environments) or you can put a comment on the Troubleshooting Forum asking for assistance from the Scratch team.

Unfortunately, these sort of problems are not uncommon when a program is being run on multiple platforms.  It's good to learn some techniques for dealing with them.

Wait...I tried fixing but the x and y coordinates keep getting messed for my ground and masker keep getting messed up. What should i do?

It is very difficult to debug someone else's code from such a confusing statement of the problem.  To do debugging, you need
    1) a clear statement of what is supposed to happen
    2) a clear statement of what happens instead
    3) the conditions under which the bug happens
    4) the source code for the program, to see why it behaves the way it does.

You have not provided us with any of these, so I don't see how we can help you other with very vague, general advice.

Oh. Sorry. About that. Well:

1) One sprite called "masker". It is supposed to mask my variables (Health). When the button "Player vs Player" is clicked, the masker is supposed to hide.

2) What happens is that the masker x and y cooridinates are different than what I orignially programmed into the game before it got uploaded.

3)When I open it on Scratch, It works beautifully. But when uploaded, the x and y coordinates are changed.

4) The scripts i put for it are:

<when green flag clicked>
<go to x   11 )y   154)
<show>

<when I receive[ play ]
<hide>

I also have the same problem for my sprite "ground".
1)Ground sprites acts as...ground. Stays one place.

2)The x and y co-ordinates are different then what I orginally programmed before I uploaded it.

3)Works perfectly when played on Scratch, but when uploaded, the co-ordinates are changed.

4)
<when green flag clicked>
<hide>
<go to x   20 )y   20 )

<when I receive[ play ]
<show>

I'll also upload the project if you want to see the whole programming script.

What do you mean by "Squeak". If its the version where you run the program at home to make games etc., then it works fine.
