Particle modding

Particles are special entities used by other entities to create visual effects such as lightning, snow, etc.

Particles are defined in .asset files which are found in /Hearts of Iron IV/gfx/particles/.

Adding a Light

Lights are special types of particles that are referred to in entities, for example the muzzle flash of the gun during the combat animation.

Here is a generic example:

light = {
    name = "name_of_light"
    
    color = {
        r = { <float> }
        g = { <float> }
        b = { <float> }
    }
    
    intensity = <float>, fade
    radius = <float>
    falloff = <float>
    
    position = {
        x = <float>
        y = <float>
        z = <float>
    }
    
    animation = {
        name = "name_of_animation"
        start = <float>
        duration = <float>
        repeat = yes
        op = <type>
        minValue = <float>
        maxValue = <float>
        curve = {
            <?>
        }
    }
}

• name is the name of the light.
• color is the color of the light. The values take decimal RGB.
• intensity is the intensity of the light, and the second value is whether it fades.
• radius is the radius of the light.
• falloff is the falloff gradient of the light.
• position is the position of the light relative to the entity using it.
• animation is animation to play for the light.

Animation

• name is the name of the animation.
• start is the starting position of the curve.
• duration is the duration of the animation.
• repeat determines whether the animation is repeated.
• op determines how multiple sources mix. Can be multiply (MUL), additive (ADD) or absolute (ABS).
• minValue is the minimum value on the curve.
• maxValue is the maximum value on the curve.
• curve is the curve used for the light.
