javacript caller and resolve?

indexofrefraction

hi klaus,

javascript in xml actions are described in the docs here...
https://krpano.com/docu/xml/#action.js

but how do you get caller and resolve if you define a krpano action in js itself?
ie. in a js plugin

Code

krpano.actions.test = function(s){
		krpano.trace(1,"test:"+s);
		// how to get caller?
	}

best, index

and another one...
how would i translate something like that into pure js for a plugin?

Code

asyncloop(caller.pressed,
        ....
    );

i guess i could use krpano.actions.asyncloop()
but this function expects action code, not js code, right?
is there a way to use such actions like asyncloop with js code?

index

Hi,

Zitat von indexofrefraction

but how do you get caller and resolve if you define a krpano action in js itself?

That's currently no documented, but there is a 'krpano.actions.actioncaller' variable which points to the caller object (when there is one, otherwise it is null).

A 'resolve' function is not available in that context, but here a simple get() could be used instead - when get() returns null use the name of the variable as value.

Sorry, that works only with actions code.
What you could do is either using jscall() in the loop code or adding a custom JS function and calling that in the loop code.

Best regards,
Klaus

thanks klaus,

all clear...

but i have another one...

Code

screentolayer(get(caller.name), mouse.stagex, mouse.stagey, currentx, currenty);

i guess setting js variables directly doesnt work in such cases, right?

so this translates to:

Code

krpano.actions.screentolayer(krpano.actions.actioncaller.name, krpano.mouse.stagex, krpano.mouse.stagey, 'currentx', 'currenty');
krpano.trace(0, krpano.currentx + '/' +  krpano.currenty);

is that correct?

plus one more...
in xml action script you check an unset variable with

Code

if(variable === null, ... );

but a direct use of this in js does not work because in javascript null !== undefined
is it correct that the above line translates to...

Code

if(variable === undefined || variable === null) { ...  }

?

best, index
