best way to do expressions using miniature avatars

#1 Post by Free Time Machine » Mon Jul 23, 2007 6:26 pm

I've decided that in my game, the main character will have a small avatar on the left of the text box. That's easy enough to copy from the demo, but what about showing different facial expressions? Should I create a different character for each expression? What's the elegant way to code this? I'm thinking of Nettestadt and Jitteh Dawn as examples of the desired effect.

EDIT: FYI, I'm also using DynamicCharacter so that the user can input a name, so the solution needs to work with this.

Nowadays, you can use ShowingSwitch to choose the expression. See the example at the website, it should work similarly for a DynamicCharacter.

I can see how ConditionSwitch could be used for the desired effect, but I am not quite clear on the usage of ShowingSwitch.

This is the code I found:

Code: Select all

init:  
    $ e = Character(
        'Eileen',
        color="#c8ffc8",
        window_left_padding=160,
        show_side_image=ShowingSwitch(
            "eileen happy", "eileen_side_happy.png",
            "eileen vhappy", "eileen_side_vhappy.png",
            "eileen concerned", "eileen_side_concerned.png",            
            None, Null(),
            xalign=0.0, yalign=1.0))
Now what? If I do:

Code: Select all

    e "How am I feeling today?"
    show eileen happy
I get an error if I don't define that image or I get two images if I do.

Am I just supposed to do this?

Code: Select all

init:
    image eileen happy = Null()
That works but seems kinda... dunno... odd.

I believe (correct me if I'm wrong, PyTom) that where ConditionSwitch selects an image based on an arbitrary condition, ShowingSwitch selects an image according to which other images are displayed. So you're supposed to have two images: one full-size character image, and one smaller image by the message window. From your description it sounds like you want just the smaller image; declaring the full-size image as Null() might work, but it "seems odd" because it's extra effort. Perhaps you want something more like:

Code: Select all

        show_side_image=ConditionSwitch(
            "eileen_expr == 'happy'", "eileen_side_happy.png",
            "eileen_expr == 'vhappy'", "eileen_side_vhappy.png",
            "eileen_expr == 'concerned'", "eileen_side_concerned.png",
(I'm not sure if there's a way to just derive the image filename directly from a variable?)

Yes exactly.

It's odd because working around the system that way allows me to use normal "show charaName.mood" statements, whereas ConditionSwitch would force me to rewrite my script and put in "show charaName" "charaNameMood = mood" pairs.

Hmm, good point-- I guess my method is the one that takes extra effort. n.n"

PyTom! Please enlighten us! What is the intended usage of ShowingSwitch? What are we missing?!

:edit:

Wait, no, I'm an idiot.

If you were using the mini picture you wouldn't necessarily use "show charaName" because they'd just show up when you had them speak. So you could:

Code: Select all

show jenny
$ jennyMood = happy
jen "I'm so happy!"

$ lucyMood=angry
lucy "Baka! What's there to be happy about?!"

jen "Huh who's that?"

show lucy
lucy "Tada, it's me! It's me!"
lucy "Stop hogging the stage!"
play sound push
hide jenny

$ lucyMood=happy
lucy "Much better."

$ jennyMood = sad
jenny "Boo hoo!"
Is that the intended usage? *blinks*

ShowingSwitch is intended for use with show_side_image, so that the side image's expression can easily match the emotion displayed on the screen. Unlike ConditionSwitch, ShowingSwitch properly deals with image prediction, so it's the better of the two to use if you can get away with it. (Even if you have to define some images to be Null().
