Kistan Specific Addons

Location: kistan_specific

These are a group of addons that only apply to things within Kistan. Most commonly, it is for specific types of fixtures.

These have the Addon Suite as a required dependency.

Roof

Location: kistan_specific/roof

`roof_shader`

Arguments:

name	description
shader	See shaders
duration	How long to run this shader (ms), `nil` if indefinite

The fragment shader gets the following parameters:

name	description
x	The x-coordinate of the pixel (higher=closer to scene)
y	The y-coordinate of the pixel (lower=closer to window the windows)
time	The time in ms since the start of the shader

Example: Makes the roof slowly change in a rainbow pattern using shaders.

-- rainbow_roof_cyclic
function roof_hue_gradient(params)
    local hue = (params.y * -40 + params.x * -10 + time * 360 / 5000) % 360;
    local intensity = 120;

    if (Scripts.rainbow_roof_cyclic:is_stopped()) then
        return "STOP"
    end
    return hue_to_rgb(hue, intensity);
end
roof:add(0, roof_shader(roof_hue_gradient, nil))

Sign

Location: kistan_specific/sign

Things for the "Kistan sign"

`sign_shader`

name	description
shader	See shaders
duration	How long to run this shader (ms), `nil` if indefinite

The fragment shader gets the following parameters:

name	description
x	The x-coordinate of the pixel
y	The y-coordinate of the pixel
time	The time in ms since the start of the shader

`sign_spiral`

Creates a spiral shader for the sign. Only argument is settings

name	type	description
width	number	The width of the spiral
invert	boolean?	Inverts
falloff_power	number	The power of the falloff of the spiral
color	RGBColor	The color of the spiral, defaults to 0x010101

The fragment shader gets the following parameters:

name	description
x	The x-coordinate of the pixel
y	The y-coordinate of the pixel
time	The time in ms since the start of the shader

Example: Creating a spiral:


local baseColor = {
    r=0x44,
    g=0x22,
    b=0x55
}

sign:add(0, sign_shader(sign_spiral({speed=5,
    width=40,
    falloff_power=2,
    invert=true,
    color=baseColor}), 100000))

Example: Creating a radar effect:

sign:add(0, set(whole_sign, 0x22, 0xff, 0xcc))
sign_dim:add(0, sign_shader(sign_spiral({
    speed=2,
    width=10000,
    falloff_power=20}), 100000))

`sign_heartbeat`

Make the "heartbeat shaped A" pulse.

Settings:

name	type	description
width	number?	The width of the entire pulse, must > 0
dimIn	number?	The width of the dim in part. dimIn+dimOut <= width
dimOut	number?	The width of the dim out part dimIn+dimOut <= width
color	RGBColor	The color of the pulse
backColor	RGBColor	The color of the background, defaults to 0x000000
speed	number?	The speed of the pulse
easePowerIn	number?	The exponent of the fading in part
easePowerOut	number?	The exponent of the fading out part

Example: Make the A pulse white

sign:add(speed*4.5, sign_heartbeat({
    color = {255, 255, 255}, 
    width = 2500, 
    speed = 0.5, 
    dimIn = 100, 
    dimOut = 2300, 
    easePowerIn = 10, 
    easePowerOut = 40}))

Drink Lights

Location: kistan_specific/drink_lights

`drinks_moving_blocks`

Makes multiple

name	type	description
blockWidth	number?	The width of one block
colors	RGBColor	Array of colors for each block.
stepTime	number?	The time in ms between each move
stepSize	number?	The number of pixels to move each step
duration	number?	The time to show this effect
flip	boolean?	Mirror the effect
flipPerRow	boolean?	Alternates mirrored and non-mirrored for each row
