"if () then () else ()" control block.

(if <> then [] else [])

If the condition is true, reports in the first slot, if not, reports in the second slot.

alexphan

define if <condition> then [1] else [2]
if <condition :: custom args> then
set [out v] to (1 :: custom args)
else
set [out v] to (2 :: custom args)

That isn't supposed to be a control block?

(if <> then [] else []:: operators)

That's not control, that's operators ;p

(if <> then [] else []:: control)

^ This is control.

Also, this ^^^

It should be operators because operators is logic as well.And also controls has no reporters and would no be right. +Semi-Support

This is literally the exact same thing as the if then else block that is currently in Scratch, no support.

pvz_pro

no support

if <> then
set [report v] to [0]
else
set [report v] to [1]
end

You just gave a workaround to your own suggestion…? xD

I know. Read carefully.

idk
it would seem kinda cool

it's built into javascript and probably wouldn't be very hard to implement (

some_boolean?"the boolean is true":"the boolean is false"

)

maybe it could be like this

(if <some condition::operators> then [value 1] otherwise [value 2]::operators)

ik it would be confusing to new scratchers but they wouldnt even need to touch it
it's just a convenient shorthand

Here's a helpful workaround:

define if <some condition> then (value1)otherwise(value2)
if <condition::custom> then
set [var v] to (value1::custom)
else
set [var v] to (value2::custom)

that would work well if scratch made functions with return values

Work-aroundable in Scratch, as a stack block:

define if <test> then (true) else (false)
if <test> then 
set [result v] to (true)

  

else
set [result v] to (false)
end

This block is included in Snap! and some Scratch modifications.

You can also directly build it into the code, too, instead of making a custom block.
Also duplicate topic? Not sure if there's an older one

good point

To be honest, the workaround is incredibly easy to understand and use, so I don't think a new block is needed for something as simple as this.

Not a workaround. An essential feature of the ternary operator is that it only evaluates the return value that needs to be evaluated. This feature would be necessary if Scratch could have recursive reporters, but even without that it would be nice as an optimization.
