Problems with Scratch 1.4's blocks

emd245

I used this script:

when (space v) key pressed
__________forever_______
|
|set (variable v) to ((mouse x) mod (mouse y))
|_______________________
and it turns dark red, because it's “invalid”.

It's because “mouse y” becomes 0, so it tries to divide by 0 and, well….

All you need to do is change the script to

when gf clicked
forever
if <(mouse y) = 0>
…
else
set {variable v} to ((mouse x) mod (mouse y))

O.K.. how about this:

when gf clicked
_______forever________
|go to x: (direction) y: (x position)
_____________________
Does this mean the sprite goes to, for example, 18 x and 18 y?

Well, no… actually it goes to the direction value for x and the original x position for y. Here's two possible methods for your idea:

set x to (direction)
set y to (x position)
OR
go to x: (direction) y: (direction)

The first question I have is why are you using 1.4. 1.4 doesn't have many of the features as 2.0 (I was there).

Because they want to use Scratch offline?

I use it for pretty much the whole project, then I spice it up in 2.0 before release. I leave the 2.0 coding until the last minute. If I ever need a custom block or a clone I just leave a message at the side of the 1.4 code until I'm ready to do it in 2.0.

Invalid Script
!?!?
when (space v) key pressed
go to x: (0) y: (0)
forever
change x by ((XY slider) / (pick random (-1) to (3))
change y by ((XY slider) / (pick random (-1) to (4))
end

For the same reason as above: division by 0.
