Hello, I'm new to Scratch. I have a problem I haven't been able to find help with. I was wondering how you could press two keys at the same time and have it work correctly. For example, when you want to jump up and go left at the same time, how do you do that without having to press the keys one at a time? It just seems like it would be more convenient to have the sprite doing two things at once without having to stall in between pressing buttons.

Hi, if you have your movement's script (including jump) inside a forever loop, take out the jump and use

when [ v] key pressed
...Jump script...::grey

There are different ways in which you can do this but it depends on how you want it so i will give you script for both ways
if you want it where they can jump but must press the left keys multiple times to keep moving left use this

when [up arrow v] key pressed
Your jump script here

when [left arrow v] key pressed
change x by ()

However if you want smooth left movement use

when [up arrow v] key pressed
Your jump script here

when [left arrow v] key pressed
repeat until <Not<key [left arrow v] pressed>>
change x by ()
end

Here is how I would do it:

when green flag clicked
forever
if <key [ Space] pressed?> then
Your jump script:
end
if <key [ Right Arrow] pressed?> then
move (5) steps
end
if <<key [ Space] pressed?> and <key [ Right Arrow] pressed?>> then
move (5) steps
Your jump script:
end
end

Let me show you a working example https://scratch.mit.edu/projects/119956269/

when [up arrow v] key pressed
if <(jumping?) = [0]> then 
  set [jumping? v] to [1]
  set [y vel v] to [15]
  change y by (y vel)
  change [y vel v] by (0)
  repeat until <touching color [#0c4] ?> 
    change y by (y vel)
    change [y vel v] by (-1)
    gotoground :: custom
  end
end

when green flag clicked
set [jumping? v] to [0]
set [y vel v] to [0]
set [x vel v] to [0]
forever 
  set [x vel v] to ((x vel) * (0))
  if <([abs v] of (x vel)) < [.2]> then 
    set [x vel v] to [0]
  end
  change x by (x vel)
  if <key [right arrow v] pressed?> then 
    if <(y vel) = [0]> then 
      change [x vel v] by (1)
    else 
      change [x vel v] by (0)
    end
  end
  if <key [left arrow v] pressed?> then 
    if <(y vel) = [0]> then 
      change [x vel v] by (-1)
    else 
      change [x vel v] by (0)
    end
  end
  if <touching [edge v] ?> then 
    set [x vel v] to ((x vel) * (-1))
  end
  turn cw ((x vel) * (2)) degrees
  if on edge, bounce
  gotoground :: custom
end

define gotoground
if <touching color [#0c4] ?> then 
  repeat until <not <touching color [#0c4] ?>> 
    change y by (1)
  end
  change y by (-1)
  set [y vel v] to [0]
  set [jumping? v] to [0]
end

Thank you all for your help, I appreciate it!

You can use broadcasting too!

forever
if <key [right arrow v] pressed?> then
broadcast [right v] // donot put the broadcast and wait
end
if <key [up arrow v] pressed?> then
broadcast [up v]
end
end

when I receive [right v]
...
when I receive [up v]
...

i have trouble too with this and none of the examples are working

How about this?

when green flag clicked
forever
if <<key [KEY1] pressed?> and <key [KEY2] pressed?>> then
Do Action
end
end

That could work actually. I can test the script to see if it works.

That won't work smoothly. The forever script runs better.

forever
if <key [W v] pressed?> then
Jump :: grey
end
if <key [D v] pressed?> then
Right :: grey
end
if <key [A v] pressed?> then
Left :: grey
end
end

This will make it so you can hold both keys at a time and have it go diagonal, although technically it's not, it's moving too fast for you to see anyway.

oy oy thanks for the help my dudes

Here's the best idea that can be done.

when green flag clicked // Self explanatory sideways movement.
forever
if <Left Movement Key> then
Move Left
end
if <Right Movement Key> then
Move Right
end

when green flag clicked // This script is for jumping only because jump scripts usually are long and would give a delay if mixed with other scripts. 
forever // Ground detections should be placed here too.
if <Jump Key Pressed> then
Jump
end
end

Thanks! but nothing works.

please make your own topic.
you are more likely to get an answer that way.

THIS IS A PROBLEM I'M FACING
What if you have a condition for example, if black color touched then stop doing this action and do this action. With one key pressed it works fine, but when i tried adding two keys to move the tank diagonally, the tank moved fine, until it touched black, when it did so it would surpass them. To see my problem I'm putting the link to my game, if you find the right code please remix it and send the link to me by replying to this post. Thank you. ^_^

Please make your own topic. The last reply was from 2018, so your post is considered a “necropost”.

Sorry about that…
