[Solved] Proper use of variable as class name

[nananame]

I can't seem to figure out the correct syntax to call a class through a variable.

Code: Select all

default Plaza = Place("something","something","THIS")

label makeCheck(where):
    "[where]" ####The 'where' variable holds "Plaza" Here I just check that it is so and indeed it is
    if where.when == "THIS":
    	#do stuff
   	

Now I know this isn't the correct way to go about it because it will look for object Place called 'where'.
The error I get is 'unicode' object has no attribute 'when'.

Of course, if I write:

Code: Select all

if Plaza.when == "THIS":

it works.

So basically what is the right syntax to get Plaza.when from where.when?

I tried:
if (where).when
if [where].when
if "[where]".when
if ("[where]".when)
and anything else I can think of.

What is the rest of your code?
Where/how do you define the class Place.
Where/how do you define the variable where?

[nananame]

Just got it working a minute ago using eval()
The rest of the code isn't relevant (Place is a class defined in init python and variable 'where' is passed through the call label)

Code: Select all

label makeCheck(where):
    python:
	    if eval(where).when == "THIS":
    		#do stuff

So this works. Basically the question should of been: how to use a string (because variable 'where' is a string) to reference class object.

Is there perhaps another way without resorting to python here that I missed? This is of course short and works fine but just wondering at this point.

getattr( store, where ).when
is probably the most Ren'Py centric

Why is where a string though? The problem would seem to be in what you are passing into the screen (a string rather than an object)

Thanks for the info!
Why a string? Quite complicated I'm afraid, it's a complex logically textual game and the actual string is a part of a longer sentence. Main thing is I now got two ways to go about it.
