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
