Hello Everybody,
I'm currently working on a scrolling platformer. I'm working on a base for it, and I have a huge problem with it. The engine has a large color fractal script that has one part managing the xvel variable. It looks like this:

when gf clicked
repeat until <(won) = [1]>
    ...
    if <not<touching color [grey]>>
        ...
        if <key [right arrow v] pressed>
            change [xvel2 v] by 0.05
        end
    end
end

This did not work. The variable xvel2 was not changing at all.
I then though that the booleans were wrong. I checked with a script that said:

when gf clicked
forever
    say <join <touching color [grey]> <key [right arrow v] clicked>>
end

The phrase when I pressed the right arrow was always "falsetrue" Therefore, the booleans should have been working right.

Does anyone see anything I overlooked? If you need to see the full script, I'll upload.

Thanks,
Programmer_112

I looked through your script, and ignoring the blanked-out parts, it should be working, so I'm predicting that something's going wrong in the parts of your script that you didn't show. So, could you show them?

What does the variable "won" display?

Should be 1, but I might have glitched it. Sadly, my dad just banned me from the computer for the rest of today for some reason. I'll check as soon as possible.

"won" is reporting 0.

Does anyone have any idea what the problem is?

Sorry for not responding earlier, though yes, I do know what the problem is, and it's not with the script that you showed us above. So let's look at this script instead:

when gf clicked
forever
 change y by (yvel2)
 if <(x position) < (0)>
  Run scripts...
 else
  change x by (xvel2)
 end

Well the problem this is causing is that your person is always below 0, and so it's x position never gets changed. Once you fix that, you should be good. ;)

I hope that this helps!

I don't know how you want this little creature to behave, but currently you have a script
that forever sets xvel2 to 0.92 * xvel
There's nothing changing the value of xvel, causing xvel2 to stay at 0 forever..
