Hi guys, I'm sure this had been addressed plenty of times, but I can't find the solution in any forums I've looked through.

So... I'm trying to make an Asteroids style game, and need to have a variable turn on (switched to the number "1") for as long as the button is held down, then turning the variable back to off (the number 0) once the button is released.

Thanks in advance smile

Easy. Just find the [block]<mouse down?>[/block] and use variables and the [block]<< <not> >>[/block] block..

Thanks for the fast reply,

I actually was looking for a key held down, not the mouse button. I found a solution shortly after posting.

I just put it in a:
When 'up key' pressed:
Forever:
If <up arrow pressed>
move 10 steps
</if>
</forever>

-------------------
Thanks!

oops... I meant "When 'up arrow" pressed" on the first line

[When green flag pressed]
[forever]
[if <key [up arrow] pressed>]
[][(insert block here)]
[endif]
[endforever]

Shouldn't this be better suited in All about scratch? Maybe?

Right. Moving.

This would actually be better as the script is only actually running when the up arrow key is pressed.

When flag clicked
forever
if <up pressed>
set _____ to 1
else
set _____ to 0

It is less efficient because that control has a short delay when detecting.

Well then simply put it in a
[blocks]
<when green flag clicked>
[/blocks]
block.
