Hey all,
I am new to the scratch environment, however kind of getting to know it and just needed a bit of clarity really so I know what I am doing wrong!

I have a ball, which needs to move vertically down the screen (I have done this), the next part of the exercise, a red box is introduced onto the stage. I have to make this ball deflect off the box, either to 10 steps to the left or right (using the PICK RANDOM [] TO []) The y_position of the ball should not exceed -175. I have done this to the best of my ability and am getting frustrated right now.. The result of the PICK RANDOM [] TO [] is to be made into a variable.

Next step; Depending on whichever way the ball is deflected (left or right), a sound is to be played depending on which way the ball goes. I have attached a copy of my entire script, which does not want to go my way!

when gf clicked
hide
show
go to [x:(0) y:(170)]
point in direction [(180)]
set [whichWay] to <pick random (-90) to (90)>
repeat until <y position> = (-175)
if <(y position)> > (-175)
move (5) steps

Here:

when gf clicked
hide
show
go to x: (0) y: (170)
point in direction (180 v)
set [whichWay v] to (pick random (-90) to (90))
repeat until <(y position) = (-175)>
if <(y position) > [-175]>
move (5) steps
end
end

And I agree, the scratchblocks syntax is quite prone to errors.

the above was an error due to me pressing submit to quickly, the tinypic link is my script in the scratch environment

cheers

Link to scratch script..

Oh ok, and I see you're making a new thread smile

(Yes, being a new scratcher is too restrictive)

FreaK001 · 2013-04-13 17:14:14

Didn't mean to create a new thread, tried to salvage whatever scratchblocks code I had to went back on the browser and hey presto.. a new thread!

Plz help sad anyone...

echristophy · 2013-04-14 11:42:54

What's happening when you run this script?

FreaK001 · 2013-04-14 12:41:16

The ball falls down the screen, hits the red box and deflects left or right which is required, it also does play a sound (as asked) but on occasion it bounces up and down on the box before it reaches the edge and plays the wrong sound?! It's real confusing because the script does work, but doesn't at other times! The only thing I can put this down to is the Pick random [] to [] block..

OverPowered · 2013-04-14 12:54:29

Try this:

when gf clicked
show
go to x:(0) y:(175)
point in direction (180)
repeat until <y position < (-174)>
if <(y position) < (-175)>
set y to (-175)
end
if <touching color [red]?>
set [WhichWay v] to ((1) + ((pick random (0) to (1)) * (-2)))
change x by ((WhichWay) * (10))
play note ((60) + ((WhichWay) * (30))) for (0.5) beats
end
change y by (-5)

Additionally, if you have any additional problems, uploading your project would allow us to actually see and mess with the scripts ourselves. Thanks. smile
