I'm trying to make a scratch project that makes a clone fall down. the clone should bounce back up on the edge tho

Gravity is a force that pulls everything with mass towards everything else with mass. You are currently being pulled on by atoms hundreds of light-years away, but their force is negligible at this distance.

Simply set the clones to be going down until they hit the edge- if you only need them to bounce and don't care about it looking too realistic, just use scratch's built-in

if on edge, bounce

block.

Otherwise, you have to program in some resistance to going up… and that gets complicated quickly.

Scratch's built-in “if on edge, bounce” just handles rotation. It's only useful for a pong game.

For what the OP (original poster) is trying to do, you need to calculate velocity, acceleration, and the correct angle to bounce off of objects.

griffpatch has a tutorial specifically for that: Physics Tutorial

I have an idea for this.
use the gravity script that I like to use:

when green flag clicked
forever
if <<not <(jump) = [0]>> or <not <(jump) < (0)>>> then
change [jump v] by (-1)
set [jump_check v] to (0)
else
if <(jump_check) = [0]> then
set [jump v] to (0)
set [jump_check v] to (1)
end
end
end

when green flag clicked
forever
change y by (jump)
end

when [your key or whatever you want to happen v] key pressed
if <(jump_check) = [1]> then
change [jump v] by (how high you want it to go)
end

or for the last one

when green flag clicked
forever
if <touching [edge v]> then
change [jump v] by (whatever)
end
end

That should work.

the equation for gravity is (-16timer^2) that is the gravity to set gravity back to zero set the timer to zero
