I was doing a project recently, and I thought that it would be nice to have a clamp block. This block would have a slot for a number, a slot for the minimum, and a slot for the maximum. If the number is greater than the maximum, return the maximum. If the number is less than the minimum, return the minimum. This would go in the operators section, and it would make code a lot cleaner than, say, writing out an entire if statement chain for that.

Instead of:

if(x > maximum) { return maximum }
else if(x < minimum) { return minimum }
else { return x };

It would be:

clamp(x, maximum, minimum);

(Sorry, I don't know how to make the scratch blocks show up in a forum post - I'm new to this!)

Please explain what half of this means

Basically, if the number you put in the block is greater than a specified max value, it would simply give you the maximum value. If you put in a number less than a specified minimum value, then it will give you the minimum value. I'm a Javascript/C# programmer, so sorry about the code.

..What??
No support, if I can't understand half of this I'm sure a 8 year old wouldn't understand it either

Okay. Sorry.

Basically (2.0)
The block restrains the value entered to a certain specified range.
If it is outside of the range because it is too large, then just spits out the maximum value that the range allows.
If it is outside of the range because it is too small, then it just spits out the minimum value that the range allows.

Example:

((10) clamp (5) maximum, (-5) minimum)

would spit out 5, because 10 is bigger than the maximum specified (5)

Sorry for the confusion

You can make a custom block for it :

define clamp () ()

and do the whole thing. Since the name of the function is not intuitive and since it's easy to build up I don't think Scratch would benefit from this.
The concept's easy too, so encountering it in other programming languages won't be a challenge.

Well, yes. I got this idea from Unity (C#). I just think it would be useful, as scratch does not allow you to make a custom block that returns a value.
(No blocks with () edges or <> edges)

By the way that is just an “”approximation“” using a block instead of a variable block, but you can set a variable to the argument later.

Oh… true. I still think it would be useful, as it saves a lot of annoying coding. I kind of forgot about being able to use variables for this. Still, I think this would be cool. Thank you, though.

If you really want it you could code it yourself, backpack the custom block with its functionalities and use it in later projects.

It would basically just be this, I believe:

The first part just checks which is the bigger number pretty much.

Okay, I made my own version using custom blocks.

define clamp (num) (min) (max)
set [return] to [0]
if <(num) > (max)> then 
set [return] to (max)
else
if <(num) < (min)> then
set [return] to (min)
else
set [return] to (num)
end
end

Now that I think of it, you could use a join block to add a specific ID to the return variable, and put every “”clamped numbers“” into a list, to avoid making an absurdly high amount of variables.

Justice for the

(clamp () from() to ())

block!

I used this in one of my turbo warp scripts:

(clamp (direction) from(60) to (120))

for gravity.

we need the

(clamp () from() to ())

block now or else I will
