I am trying to make a game but I dont know how to make my sprite jump or wall jump please help me

there are a lot of platformer engines that use many different types of jump codes

h e l o t h e r e

well, use gravity, like when green flag clicked, go to somewhere….. then something like that, or create costumes of the sprite jumping

I still dont understand what to do

heres the link of my game in which i have made my sprite jump.you can copy the code

Hi! There's numerous ways of making a sprite jump & even going further to make it realistic/smooth with physics but a simple way to start out, you can do this & explore from there:

when green flag clicked
forever
if <key [space v] pressed?> then
glide (0.1) secs to x: (0) y: (75)
glide (0.1) secs to x: (0) y: (0)
end
end

The above means:

When the flag is clicked, whenever spacebar is pressed, it'll make the sprite move up & back down again to it's original position if it starts out at x = 0 , y = 0.

You can simply change the height of the jump by changing the 'y value'!

While the above code works, it it much TOO simple and unrealistic. There’s no actual gravity or physics. That’s just a generic movement code.
I would expand on that and experiment with actual gravity movement with variables.

Yes correct, as mentioned it's a simple way to start out & OP can explore from there.

I believe in giving solutions that is simple enough rather than overwhelming a potentially still learning Scratcher. If they want a more realistic & complex approach after that, we can always expand on it in the later stages. There is no such thing as ‘too simple’, if it works it works. We should always start out simple & work our way up.

this is the easiest way to make a sprite jump

when this sprite clicked
repeat (10)
change y by (10)
end
repeat (10)
change y by (-10)
end

Ues a tutorial

This is kinda like a flappy bird jump

when green flag clicked
forever
if <key [space v] pressed?> then
change y by (20)
end
end
when green flag clicked
forever
if <not <touching [ground v] ?>> then
change y by (-5)
end
end

I need a little better code

Do elaborate on the type/feature of jumps you want & even share the game project so we can help provide with more elaborate codes that is suitable for your game!

Alright, that's fair enough.

I already posted my jump code in at least 2 other topics anyway. It's a little more advanced, and a little more realistic with a gravity variable, but I'll let them decide what they want.

Use variables:

forever
change y by (velocity y)
change [ velocity y] by (-1)
if <key [ space v] pressed?> then
set [ velocity y] to [20]
end
end

You have to add a bit more code to make it stand on something and not fall endlessly.

a little more code because i dont know how to make it jump off any object

this should work

when [up arrow v] key pressed
repeat (3)
change y by (3)
end
repeat (3)
change y by (-3)
end

and if its touching do the same thing but with

when [ up arrow v] key pressed
if <touching [sprite? v] ?> then
repeat (3)
change y by (3)
end
repeat (3)
change y by (-3)
end
end

The easiest way to do it would be

when [up] key pressed
repeat (...)
change y by (10)
end
repeat (...)
change y by (10)

end

To make it jump off an object, you will have to make it fall until it reaches the ground. Try this script:

when [space v] key pressed // when you want to jump
set [y vel v] to (10) // change this to adjust how tall you want the sprite to jump (10 gives 55px of upwards movment)
repeat until <touching [platform/ground v] ?>
change [y vel v] by (-1)
change y by (y vel)
end

This script is not much more complicated than the simplest up-down jump script, yet it includes gravity and also lets you jump to a platform of a different height, so I highly recommend you to try it. Also, you should take a look at my platformer for some useful scripts: https://scratch.mit.edu/projects/415577135/
