Lemma Soft Forums

The original article on the wiki has a bit of an error that can really throw newbie programmers for a loop.
I'm just adding the missing apostrophes for future reference.

Edit: 6/2/2012. Another newbie edit. If you use folders, the original cookbook suggests "/folder/image.png". There is no need for that first slash!!! Removed that first slash from the comment below.

Showing layered sprites with different emotions

Have you ever wanted to make a layered image but you didn't want to declare separate statements for each one? Are you tired of using "show eileen happy at center with dissolve"?

Then this is for you! Welcome to the world of LiveComposite and dynamic displayables using ConditionSwitch! You'll only need to declare something like "$ Janetmood = mad" to change the emotion on her face or the pose and any number of fun things.

Excuse my ignorant question, but is it possible to use transitions with this method?

This is actually an excellent question. I'm looking for the answer to it myself!!!

I use a different method (composite, building the expression in-game) but what I do is to have a backup of the character and switching between them.
(Eileen and Eileen2, both are linked to the speaker (especially important if you use lip flap).)
I change the expression in 2, use a transition and switch back to 1, then again to 2, then to 1...
Not elegant but it works. =o

Hmmm...that's an interesting and clever way to do it! It seems there must be some way of doing it so it's not so redundant.

Wouldn't it be possible to define 2 pictures as one picture? And then just use it as normal sprites?

I'm not sure but is it what you're looking for?

Hello! This is quite a helpful code. Sorry if the questions give hints at my noobness haha.

1. Does the init go to the main script or the separate script?
2. Is there a way to place image scripts as a separate rpy file and call them on the main script?
3. Instead of 9 mouths, 4 eyes and 5 eyebrows, would it be easier to call whole faces? I'm just concerned with the placement of the images since the graphics might look just a hairline off but still produce weird results.

Thanks!

Someone please correct my explanations here, as I'll make my best attempts using butchered terminology and a tenuous grasp of RenPy. (Note to Sabotage--I'm actually having someone far more skilled than I am doing the harder programming tasks, thank goodness.)

1. I believe "init:" indicates wherever you want RenPy to start executing code. It can go into an .rpy file you want...that's where the computer will start following instructions (and initializing variables, etc.). Everything under init is run every time the program is run.

2. if you mean the sprite images? or the the background images? yes, you can declare all your background images in one .rpy file, and sprite images in another. Just make sure init: is at the top of those .rpy files, so RenPy knows to run all of them (initialize them) before it actually starts the code for the game. You can even put numbers after "init" to tell RenPy which order to run the .rpy files you've got. Init: will be executed before init 2:, for example.

3. Yes, people use all sorts of methods to create expressions. If all of your layers are exactly the same size (imagine a transparent layer with a single mouth that you precisely over a same-sized layer with a body), everything will already be placed exactly where it needs to be, and RenPy will stack them for you. Personally, I put a lot of time and energy combining the different eyebrows, eyes, and mouths together, though numerous artists won't use this method because they feel the entire expression should be captured in the pose of the body itself. I'm all about facial expressions though, so I currently have 70 different expressions coded for my main character to be used throughout my game. It's very much a personal preference.
