I need help making the players head move wen ever I touch the screen, I’m not sure if I havet to make a player function or a touch function please help

– Use this function to perform your initial setup
function setup()
displayMode(STANDARD)

availableTests = { Test2(), Test1() }
currentTest = availableTests[1]

parameter.integer("SceneSelect",1,#availableTests,1)

parameter.number("Size",50,500,150)
parameter.number("CamHeight", 0, 1000, 300)
parameter.number("Angle",-360, 360, 0)
parameter.number("FieldOfView", 10, 140, 45)


the3DViewMatrix = viewMatrix()
parameter.watch("the3DViewMatrix")

-- These watches are evaluated after draw() is finished
-- Thus the contents are not as interesting
parameter.watch("viewMatrix()")
parameter.watch("modelMatrix()")
parameter.watch("projectionMatrix()")

end

– This function gets called once every frame
function draw()
– Set the currentTest to the selected scene
currentTest = availableTests[SceneSelect]

-- First arg is FOV, second is aspect
perspective(FieldOfView, WIDTH/HEIGHT)

-- Position the camera up and back, look at origin
camera(0,CamHeight,-300, 0,0,0, 0,1,0)

-- Write this into a variable so we can watch() it
-- at this point in time
the3DViewMatrix = viewMatrix()

-- This sets a dark background color 
background(83, 181, 228, 255)

-- Do your drawing here
currentTest:draw()    

-- Restore orthographic projection
ortho()

-- Restore the view matrix to the identity
viewMatrix(matrix())

-- Draw a label at the top of the screen
fill(255)
font("ArialRoundedMTBold")
fontSize(20)

text(currentTest:name(), WIDTH/2, HEIGHT - 30)

end

Test1 = class()

function Test1:name()
return “Codea Primitives in 3D”
end

function Test1:draw()

background(144, 209, 144, 255)

Are you talking about moving the camera angle?

#did I help?

You probably want to make a touched(touch) function, and give the player a touched function too.

I pm’d you the solution
