Help- How to make a sprite jump correctly- not fly!!!

_Tigerjack_

Hello,
I'm making a platformer and really want to know how to make my sprite jump correctly. I made it so that every time the up arrow key is pressed, the sprite changes Y by 20. But if you hold down the Up arrow, it keeps on changing Y. I haven't figured out how to stop that but still keep the sprite moving sideways. Can anyone help? Here's the moving script (It's very basic):

when green flag clicked
set [ Costume#] to [1]
set [Lives:] to [3]
set size to (80) %
forever
    
if <not <touching [Solid] ?>> then
change y by (-10)

    
end
if <key [Up Arrow] pressed?> then
change y by (20)

end
  if <key [Right Arrow] pressed?> then
change x by (15)

end
if <key [Left Arrow] pressed?> then
change x by (-15)
      
    
end
if <(Lives) = [0]> then
    
stop [All]
end

end

I wouldn't like to change this too much, but I will if it's the only way. Thanks!!!

“Solid” Is a sprite, and “Lives” and “Costume#” are variables- they didn't turn out right.

So you should only allow the up arrow to have an effect when touching something solid.

So

forever
    
if  <touching [Solid] ?> then
if <key [Up Arrow] pressed?> then
change y by (20)

end
else
change y by (-10)

    
end
if <key [Up Arrow] pressed?> then
change y by (20)

end
  if <key [Right Arrow] pressed?> then
change x by (15)

end
if <key [Left Arrow] pressed?> then
change x by (-15)
      
    
end
if <(Lives) = [0]> then
    
stop [All]
end

end

I wouldn't like to change this too much, but I will if it's the only way. Thanks!!!

Good that this helped but no need to necropost and bring it back to the top of the forum just to thank me (or anyone). Just treat old help as being free with no need to acknowledge.

Use this script (I'm sorry for necroposting but i need to help):

when green flag clicked
if <key [Up arrow v] pressed?> then
repeat (10)
change y by (15)
end
end
repeat until <touching [Ground Sprite v] ?>
change y by (-10)
end

when green flag clicked
set [jump] to [0]
forever
if <touching [platforme] ?> then 
if <key [up arrow] pressed?> then
set [jump] to [12]
end
else
change [jump] by (-1)
end
change y by (jump)
end
