you should have a -bounce- block as well as a -if on edge bounce- block as otherwise you have to make complicated scripts

There is already a

 

if on edge, bounce

block.
As for the bounce block, it cannot know how to bounce in all circumstances. So, I don't support.

Nice suggestion! It sounds like it would be helpful to various Scratchers. The problem I see with a bounce block though is how are you even going to code that? Different people code their bounces differently, and even the code behind it is complex. It could easily be a source of lag for a project, so I don't support.

You should be able to put on edge in a if block, then just boulle in another. You could modify it, so on the bounce block, have a drop down menu to set bounce strength to__, set bounce direction to: up, down, left, right, same direction sprite came from. I support it

your right it takes alot of code but its not all active at the same time and it only rarely makes lag

I think the point ErnieParke was trying to make was that it would be impossible for a bounce script to know how to bounce. The screen edge is easy because it is flat and stationary. Sprites are any shape and can be moving, spinning and represent different masses and elasticity so creating a generic bounce block would be impossible and is the reason we have all those other lovely blocks so we can do it ourselves just how we want. No support I'm afraid.

You can code it like this:

when green flag clicked
forever
    
if <touching [Sprite2 v] ?> then
    
bounce
end

end

seanbobe

if <touching color [white(or the color of the background)] ?> then
    bounce
end

I tried this duplicate, but unfortunatley @paddle2see* decided to shut me down.

To bounce you can use this :

point in direction (((-1) * (direction)))

Yes, you can.

Yes, if you are bouncing off a vertical line.

It is actually possible to make a script that bounces off a line at any angle, or off a circle. Unfortunately it is not possible to bounce off a complex shape this way, which is why there is not a bounce block and there probably never will be.

No, it's not possible. Plus, you'll need calculus for this thing, which Scratch (and probably Flash itself) doesn't support.

If you you want to make stuff bounce off of whatever just do if touching (whatever) move -10 steps.

little_kitten

No support because if you say forever wait (1) secs, bounce, if it wasn't touching anything, it would bounce off to?

shoresbeep

No support because:

point in direction ((180) - (direction))

cutekids100

How about

if touching [Sprite1 v], bounce ::motion

?

You could use something like this for bouncing off a red and black line (named Sprite1)

when I receive [ v]
repeat until <[w] = [1]>
if <touching color [#ff0000] ?> then
point in direction ((([sqrt maybe? v] of (direction)) * ((90) + (([sqrt? v] of ([direction v] of [Sprite1 v]))))))
end
if <touching color [#000000] ?> then
point in direction ((([sqrt maybe? v] of (direction)) * ((((90) + (([sqrt? v] of ([direction v] of [Sprite1 v])))))) * (-1)))
end
move (3) steps
end

I don't know if this will work, but I think it should use direction sensing instead of color sensing for the bounce physics.
