Dissolve FX for Defold

This is an example of implementing the dissolve effect for sprites for the Defold game engine.

[!NOTE] Use FastNoiseLite to generate an unique and cool noise texture!

Quick Start

1. Add this project as a Defold library dependency. Open your game.project file and in the dependencies field under project add:

https://github.com/indiesoftby/defold-dissolve-fx/archive/main.zip

2. Next, add two textures to sprite's atlas: noise and ramp. The noise will be used to animate sprite's dissolve, and the ramp will be used to create the burning effect.
3. Set dissolve_fx/materials/sprite.material as the material of the sprite.
4. Do some magic in your script:

local dissolve_fx = require("dissolve_fx.dissolve_fx")

function init(self)
    dissolve_fx.init("#sprite", "noise", "ramp", "cover") -- args: sprite component with dissolve material, noise image name, ramp image name, scale mode (`cover`` or `stretch``).
    go.set("#sprite", "dissolve.z", 0.25) -- size of the fire. Adjust subjectively to your eye!
    go.set("#sprite", "dissolve.w", 0.0) -- to control the fx, 0.0 - 1.0

    -- Play the FX in the loop
    go.animate("#sprite", "dissolve.w", go.PLAYBACK_LOOP_PINGPONG, 1, go.EASING_LINEAR, 3)
end
