Hmm, A boolean was expected 🤔 I guess its a boolean otherwise code wouldn't have been compiled.

[turansky]

It can be 0 🙂

[turansky]

In most “boolean” cases it works as false

[turansky]

But 0 is short 🙂

Comparision operator returns short? blob thinking fast

Imma confused a bit 😅

0 can be used in JS platform as short variant of false

[Animesh Sahu]

Still didn't really understood what I did wrong 🤔

[turansky]

Will it work with !! ?
!!this == KeyState.KEY_DOWN ?

[Animesh Sahu]

Is that a syntax 👀

[Animesh Sahu]

(I'm not aware of)

[turansky]

!!(this == KeyState.KEY_DOWN)

[turansky]

Brackets required

[Animesh Sahu]

I guess you mean (this == KeyState.KEY_DOWN)!! ?

[Animesh Sahu]

I don't think its result is null 🤔 a comparision is either true or false, isn't it?

[turansky]

No, I mean double not

[turansky]

Boolean operation

[Animesh Sahu]

Oh, ok, wait lemme see
