television lines effect

[Gazza]

hello there, first time i'm posting here.

i was wondering, is it possible to add a filter on top of the screen (including gui and textbox) to simulate a old tv screen?

i searched the forum but i didn't find any doable solution.

thanks in advance

you could just do a transparent png animation and layer that on top of your scene!

i just created a custom screen and added my file but nothing is showing

sorry i'm not very flexible with screens

If you are able to show how you did so, we may be able to point out what went wrong.

I guess if you wanted to do a frame animation of the tv, you could treat it as a layer like this:


#define animations

image TVWarp:
"image1.png"
pause .5
"image2.png"
pause .5
"image3.png"
pause .5
repeat

#define your background

image your_background = "background.png"

#call the animations within whatever you're going to label it

label whatever:
scene your_background
show TVWarp



something like that could work for you

Code: Select all

screen over_image:

    zorder 300

    add "gui/overlay/static.png"

i only wrote this line of code over the other codes in screens.rpy, but i'm stuck

wait, i meant like an image that stays on top of the screen for the rest of the game, even when you open the main menu or the settings

i'm not sure labels can do that, correct me if i'm wrong

You can create a new layer and show your image there.

Code: Select all

image scanlines = "images/your image.png"

Code: Select all

init python:
    config.layers = [ 'master', 'mask', 'transient', 'screens', 'overlay' ]

Code: Select all

label start:
    
    show scanlines onlayer mask
    rest of your game...

See here: viewtopic.php?f=8&t=20699

You can also experiment with alpha and/or additive values to fine-tune the effect. For example:

Code: Select all

image scanlines:
    "images/your image.png"
    additive .5

okay so, i added your code in my script, and everything works fine, but it's not showing over my gui nor the title screen, am i doing something wrong? sorry for my ignorance

[Donmai]

am i doing something wrong?

No, you are not. That's how that example really works, sorry.

You can use:

Code: Select all

label before_main_menu:
	show scanlines onlayer mask
	return

Along with that, you can put the layer 'mask' as the last element in the config.layers, like this:

Code: Select all

init python:
    config.layers = [ 'master'', 'transient', 'screens', 'overlay', 'mask' ]

However, even with that, you'll have to put "show scanlines onlayer mask" every time you change the scene, because when that happens, the layer is cleared, and I don't know if there is a way to prevent it from being cleared. Sorry.

that's exactly what i wanted to do, it even shows on the setting screen!

it's ok if have to declare it every time, thank you very much for your help <3
