parallax functionality does not work properly with large, connected BGOs.

Spoiler: show

This is a library that allows you to control more about how a BGO looks via extra settings. It supports movement, rotation, opacity, scaling and parallax. It's also multiplayer/split screen compatible.

How to use: show

Installation

To install, place the files from the zip folder into your level/episode folder. Then, add the following line to your luna.lua file:

Code: Select all

local extraBGOProperties = require("extraBGOProperties")

There should now be settings on the right side of the screen when selecting a BGO.

Movement

In the settings box, there is an option labeled "movement". This works similarly to the Graf NPC's patterns. You can set the following values: x, y, scaleX, scaleY, rotation, and opacity. Examples on how to use these are below the option. Note that "t" is the number of seconds since the level started, x and y are measured in blocks, rotation is measured in degrees and opacity should be between 0 and 1.

Default Settings

Via code in a luna.lua file or elsewhere, you can specify default settings for each BGO ID. For example, after loading in the library:

Code: Select all

extraBGOProperties.registerID(1,{
    movementFunc = function(v,t)
        local data = extraBGOProperties.getData(v)

        data.offsetY = math.sin(t*4)
    end,

    scaleX = 2,
    scaleY = 2,
})

The first number is the BGO ID, and the rest of the values are settings. The valid settings to enter are offsetX, offsetY, scaleX, scaleY, rotation, opacity, parallaxX, parallaxY, pivotX, pivotY and finally, movementFunc. The movement function works similarly to the movement box, except you must change things via the BGO's data table.

What's the code for the bouncing bush/hill thing?

Spinning, swaying and shifting I understand
but how do I make that wobbly hill?

local stretch = sin(t*8)

scaleX = 1 + stretch*0.1
scaleY = 1 - stretch*0.075

Updated this library to include some extra features: colour changing (allowing you to tint a BGO) and shader support. Note that shaders and their uniforms are only supported per-ID rather than per-BGO, and therefore must be set up through Lua code. A function can be set to change their uniforms once per frame, per camera.

Sample for setting up a shader:

Code: Select all

extraBGOProperties.registerID(1,{
    getUniformsFunc = function(id,camIdx)
        return {
            time = lunatime.tick(),
        }
    end,
    fragShader = "wavy.frag",
})
