Move() and cubic functions

[DaFool]

Does Ren'Py support vector graphics?

[PyTom]

No, Ren'Py is currently limited to raster graphics. (JPG, GIF, PNG, and probably a few other minor formats that aren't worth worrying about.)

Mmm... *worried eyebrow*... I tried copying MoveTransition as it is in my script (in an init, python block), renaming it MoveEaseTransition and I get this when I try to use it (show something at someplace with MoveEaseTransition(sometime)) :

Ren'Py Version: Ren'Py 5.5.2b

Seems like something is not defined or it doesn't find any image to move ? Note that MoveTransition works in the same script of course.

Seems like I'll be posting the working code tomorrow when I have this cleared up ^^;. Would rather release something complete.

[monele]

*bump* ?

[PyTom]

Can you send me an example script to take a look at? It's hard to tell from just the traceback alone, when I don't have important parts of the code.

[monele]

Sent ^^

Line 297 is the first "init:" line ^^;

[PyTom]

Sorry, it's renpy.curry, not renpy.curry.curry.

[monele]

It is renpy.curry.curry in story.py though... strange ..... and it's still crashing >.<...

I've curried the MoveEase function too (didn't at first) and changed the call to "renpy.display.layout.MoveEase" to "MoveEase", since that'd be more logical ^^;... It compiles, runs, but then crashes with this :

    show test at Position(xpos=0.8, ypos=0.8) with MoveEaseTransition(2.0)

Looking for the attribute, I find it in DynamicDisplayable... But at that point, I don't know what to conclude ô_o;... should MoveEase have such a function ? Should it somehow be defined as a child of DynamicDisplayable or something? @_@

[PyTom]

In MoveEaseTransition, call _MoveEase rather than MoveEase.

The confusion here is because there are two versions of Move in Ren'Py:

Move (aka, renpy.store.move) is the one you normally see, and this is a currying version of renpy.display.layout.move.Move, and is equivalent to MoveEase.

renpy.display.layout.Move is the non-currying version of Move, and is equivalent to _MoveEase.

One of these days, I need to document how to write displayables, at-functions, transitions, and the like.

[monele]

Ok, I think I understand ^^ *tries*...

Yuhh ;o;... still the same error ;o;.. Should _MoveEaseTransition be a def or a class ? ô_o;... *joins files in case it's something stupid like a typo...*

[PyTom]

A def, I think.

Can you send me a working game with all of this? It's hard to debug things when I can't run the code.

[monele]

Mm, yes. It should be around 50mb, so... should I use YouSendIt or should I attach it to a post ?

[PyTom]

Email is probably better, so we don't cutter the server with a large file.

[monele]

OK, will send this in multiple e-mails (my limit is around 10mb...).
