How to make a ripple effect underwater?

[Kylebot2000]

I'm going to have the ability to dive underwater hevily used in my newest game, but I need some help. I've got the tinting perfect, but how can i make the screen ripple as if the camera is underwater? Sorry for the short post, but my laptop is about to die.

There is no way to get an actual physical ripple effect, not even with scripts. The lag would probably be unbearable, as well. Your best bet is to just use the Underwater fogs.

Bump.

And also, you're exaggerating a little bit. What about the ripple effect that's present while you're in the default battle system? It couldn't be THAT hard to do it...?

In the default battle system, that effect is achieved by taking a static background and applying a wave effect to it.  This is an excerpt from Spriteset_Battle:

    @battleback_sprite = Sprite.new(@viewport1)
 #....
    # Setting parameters for wave
    @battleback_sprite.wave_amp = 8
    @battleback_sprite.wave_length = 240
    @battleback_sprite.wave_speed = 120

However, you want to apply a ripple effect to the entire screen, while it is active.  Normally that's practically impossible because the screen is composed of many sprites, and also because tilemaps don't support wave effects like sprites do.

Perhaps you could create a water-scenery parallax (see the "create_parallax" method of Spriteset_Map) and apply a wave effect to it.  However, the parallax is a plane, not a sprite, and planes don't support wave effects.

You could, atleast I think, create a series of pictures used with very little wait to appear on the screen with a low opacity, mimicking the effect of a ripple. Like, say, you created 5 pictures, each one slightly difference, and strung them together, and then used these as a common event whenever he dives? It's annoying, but it may be the only thing you could do.

Are you looking for a dynamic ripple (constantly moving), or a static ripple like the battle system?

For dynamic, build on Kain's idea & use an autotile with the priority set to 5 so it is on top of everything else, including the player.
(unless that's no longer possible in VX. I don't have it anymore, it expired & I didn't buy it.)

For static, you could come close by editing the tileset & applying a wave-blur effect to each individual tile.

Be Well
