How to make stages

First of all you need a name for the stage. Here i will just use "something"

Start

Then you need the sprites / images for backgrounds and background characters. Usually they are put into sprites/something folder or images/something folder.

Dont forget that for sprites you need to convert the XML to a JSON file.

Middle

You place something.json into the stages folder and add this stuff into it. It contains basic variables you will have to change for your stage.

{
	"boyfriend": [0, 0],
	"girlfriend": [0, 0],
	"opponent": [0, 0],

	"camera_boyfriend": [0, 0],
	"camera_opponent": [0, 0],
	"camera_girlfriend": [0, 0],
}

Then, you will have to script your images and sprites into the game yourself. I made a good API for this with image / sprite types so it isn't too hard. You can check some existing stages and the type documentation for help.

Also for more stage script manipulation you need to check the Scripting Functions page.

Small example stage script:

local myTypes = require("modules.types")

local module = {}
function module.onCreate(song)
    local back = myTypes.Image("images/stage/stageback.png")
    back.layer = -10
    back.position = myTypes.Vector2(-800, 50)

    local front = myTypes.Image("images/stage/stagefront.png")
    front.layer = -1
    front.position = myTypes.Vector2(-900, 1000)

    local curtains = myTypes.Image("images/stage/stagecurtains.png")
    curtains.position = myTypes.Vector2(-1150, 50)
    curtains.modifier = 1.3
    curtains.layer = 5
end

return module
