Modifying scripts

Yeah. Some of these scripts are just meant to be examples for people to learn from rather than useful in their own right. I need to add a simple way to copy the built in scripts to the user's Open Brush folder for further editing.

Currently the simplest way to see them is to go to here: https://github.com/IxxyXR/open-brush/tree/experiments/moonsharp/Assets/Resources/LuaScriptExamples

For example here's "ManyAround":

Settings = {
    space="widget"
}

Widgets = {
    copies={label="Number of copies", type="int", min=0, max=36, default=4},
    hueShift={label="Hue Shift", type="float", min=0, max=1, default=0}
}

function Main()
    pointers = {}
    Colors = {}
    theta = 360.0 / copies
    for i = 1, copies - 1 do
        table.insert(pointers, {position={0, 0, -i/4.0}, rotation={0, i * theta, 0}})
        if hueShift > 0 then
            newColor = brush.lastColorPicked;
            table.insert(Colors, color.newColor)
        end
    end
    return pointers
end

Settings = {
    space="widget"
}

Widgets = {
    copies={label="Number of copies", type="int", min=0, max=36, default=4},
    hueShift={label="Hue Shift", type="float", min=0, max=1, default=0}
}

function Main()
    pointers = {}
    Colors = {}
    theta = 360.0 / copies
    for i = 1, copies - 1 do
        table.insert(pointers, {position={0, 0, -i/4.0}, rotation={0, i * theta, 0}})
        if hueShift > 0 then
            newColor = brush.lastColorPicked;
            table.insert(Colors, color.newColor)
        end
    end
    return pointers
end

I've actually forgotten to wire up Hue Shift so it's not currently doing anything. There's a simplified version of this script in the docs: https://docs.openbrush.app/alternate-and-experimental-builds/runtime-scripting#symmetry-scripts

Feature: Plugin Scripting

function Main()
    copies = 12
    pointers = {}
    theta = 360.0 / copies
    for i = 1, copies - 1 do
        table.insert(pointers, {position={0, 0, 0}, rotation={0, i * theta, 0}})
    end
    return pointers
end

function Main()
    copies = 12
    pointers = {}
    theta = 360.0 / copies
    for i = 1, copies - 1 do
        table.insert(pointers, {position={0, 0, 0}, rotation={0, i * theta, 0}})
    end
    return pointers
end

Could benefit by the ability to set distance between strokes

try this one. it should behave the same as the 4 way mirror in Experimental Mode. It's a good script to learn from as it's so simple.

Very interesting. What's the table.insert function do?
