How to make your sprite move left and right

joshly50

To make your sprite move left and right follow this script

To move right

Go to events and drag block called (When space key pressed) change it to (When right arrow key pressed)
Then go to motion and drag move 10 steps and change it to 30 and snap the blocks together.

To move left

Go to events and drag block called (When space key pressed) change it to (When left arrow key pressed)
Then go to motion and drag move 10 steps and change it to -30 and snap the blocks together.

This is correct.
But you can add some fun.

For instance just try with the cat:

when [right arrow v] key pressed
repeat (10)
move (3) steps
next costume    
end

The cat will move 30 steps but you will see it move its feet.

That's quite a good way.

There is a much better way than that.

when gf clicked
forever
if <key pressed [left v]>
change x by (-5)
next costume
end
if <key pressed [right v]>
change x by (5)
next costume
end
end

Hope this helps

Yes the if key pressed option allows for a faster response. If that isn't needed or not suitable for your project, then the when key pressed block does the job.

when green flag clicked
forever
    
if <key [left arrow v] pressed?> then
set [moving direction v] to [left]
if <key [right arrow v] pressed?> then
set [moving direction v] to [right]
    
end
    
end
end
when green flag clicked
forever
    
if <(moving direction) = [right]> then
change x by (5)
if <(moving direction) = [left]> then
change x by (-5)
    
end
    
end
end

hopefully that helped

and always remember

when green flag clicked
forever
    
if <got help from digthebone.> then
know he is awesome

Those could be combined into one, more efficient script.

Scratching_Vornado

Using

move () steps

isn't very good as it doesn't work very well. Sometimes it moves once, stops, then moves forward again. As other people said, you should do something like this:

when green flag clicked
forever
    
if <key [right arrow v] pressed?> then
change x by (30)
    
end
if <key [left arrow v] pressed?> then
change x by (-30)
    
end
end

Maybe through in a

wait (0.01) secs

in there.

typemaster

X and Y are the coordinates of the location of the sprite as you probably already know.
Here is the most efficient way to make a sprite move left and right:

when [right arrow] key pressed
change x by (5)
//this is for moving right

when [left arrow] key pressed
change x by (-5)
//this is the script for moving left

Hope I helped you!
You will find that most of my projects use those scripts that I gave you.

Like this!

when [-->] key pressedmove (10) steps

r123a

when [left] key pressed
    
end
change x by (-10)

end

r123a

sorry, I made a mistake.

You just need When Flag Clicked change x by (how ever much you want). If you want it to go left make it a minus number

How do you make scratchblocks?

When you make a post, look at the icons above the bit where you type. One of those is a small blue block with a down arrow next to it. Click on there and you can then click on the blocks. Alternatively, you can do what I do and type them manually.

Happy (scratchblocks :: operators) :: motion

minecrafternotch

In the latest version of scratch it's easy.Two ways are with a mouse,and by arrow keys

Mouse

when this sprite clicked

glide (1) secs to x: (mouse x) y: (mouse y)

Arrows:

when [right arrow] key pressed

repeat until <touching [other block] ?>
move (3) steps

end

when I receive [Fame and Glory]

go to [The moon and live life]
