Distributing Code Over Tabs

An example of how to distribute code over a number of tabs (provided by John Millard/Simeon Saens).

John Millard has done this with the Physics Lab Example Project. There, he has a number of tabs (Test1, Test2, Test3, ...) and in the Main file he creates a parameter,integer(), as you drag the slider the physics scene changes from Test1 to Test2 and so on. There are a number of ways you could do this, the most basic would be:

Test1 - draws a rect

-- Test 1 Scene
Test1 = class()

function Test1:init()
    -- init scene (treat this as if it's setup() in Main)
end

function Test1:draw()
    -- draw a rect
    background(0)
    fill(255,0,0)
    rect(0,0,100,100)
end

function Test1:touched(touch)
    --handle touches
end

Test2 - draws an ellipse

-- Test 2 Scene
Test2 = class()

function Test2:init()
    -- init scene (treat this as if it's setup() in Main)
end

function Test2:draw()
    -- draw an ellipse
    background(0)
    fill(0,255,0)
    ellipse(50,50,100,100)
end

function Test2:touched(touch)
    --handle touches
end

Main - switch between scenes

-- Main
function setup()
    scenes = {}
    scenes[1] = Test1()
    scenes[2] = Test2()

    -- SceneIndex parameter from 1 to number of scenes
    parameter.integer("SceneIndex",1,#scenes)
end

function draw()
    scenes[SceneIndex]:draw()
end

function touched(touch)
    scenes[SceneIndex]:touched(touch)
end
