What's wrong with my if statement?

[Frank]

(e)=>{{e.other.controllerAcc == 4.3}(?)(e.this.color = [1, 1, 1, 1])(:)(e.other.density = 1)}
What the hell is wrong with this onCollide code? I get no error messages or anything. It just doesn't execute. I can't figure out what I'm doing wrong here, and it's very frustrating.

Well, your first problem is that it's not an if statement. What you've got there is a ternary conditional operator.

Aside from that, I have no idea.

And welcome back to the boards Frank!

{e.other.controllerAcc == 4.3 ? {e.this.color = [1, 1, 1, 1]} : {e.other.density = 1}}
will work fine.

@frank Did you place the brackets around the ? and : or was it algodoo ?

[Frank]

Algodoo did that.
Thanks Killinich, your script works. I can't figure out what I was doing wrong because I'm pretty sure I started with that, but now it works now and I can continue with my project.

Frank, I think the original problem was the parens around the then/else sections, instead of curly braces.

Code: Select all

{if} ? (then) : (else)

instead of

Code: Select all

(if) ? {then} : {else}

. I've noticed that the new (awesome) script menu in 1.7 puts parens around things it doesn't recognize, sometimes, rather than marking them as invalid syntax.

Daniel, its always done that.

hey i know it:

(e)=>{your statement == SOMETHING ? {if it is} : {if it is NOT}}

so: (e)=>{ speed1 == speed2 ? {speed1 = speed2} : {speed1 = 10 (for example!!!) }
^^
''=='' can be: == (eaven)
>= (bigger than)
<= (smaller than)

[Mystery]

Well your kind of right, but also horribly wrong.

== Equal To
> More then
< Less then
>= Equal to or More then
<= Equal to or less then
!= Not Equal to

{If}?{Then}:{Else}
If i go to the mall, Then i'll buy shoes or Else i go barefoot

But it's not an if statement!

It's more like if conditional evaluates to true ? execute this code : otherwise execute this code

There is a difference you know. And I do have an open suggestion ticket for real if statements, or at least better elseif statements
