Description

Sets the position of the listener in a 3D environment. <syntaxhighlight lang="lua"> Sound.setListenerPosition(x,y,z,vx,vy,vz,dx,dy,dz,ux,uy,uz) </source>

  Note: please notice the dot instead of the column Sound.setListenerPosition(...)

Parameters

x: (number) X coordinate of the listener
y: (number) Y coordinate of the listener
z: (number) z coordinate of the listener optional
vx: (number) X component of listener's velocity optional
vy: (number) Y component of listener's velocity optional
vz: (number) Z component of listener's velocity optional
dx: (number) X component of the direction the listener is facing optional
dy: (number) Y component of the direction the listener is facing optional
dz: (number) Z component of the direction the listener is facing optional
ux: (number) X component of up direction relative to the listener optional
uy: (number) Y component of up direction relative to the listener optional
uz: (number) Z component of up direction relative to the listener optional

Example

<syntaxhighlight lang="lua"> local audioScale=0.02 local scrW,scrH=application:getContentWidth(),application:getContentHeight() Sound.setListenerPosition(scrW*audioScale/2,scrH*audioScale/2,0,0,0,0,0,1,0,0,0,1)

local dot1 = Bitmap.new(Texture.new("1.png")) dot1:setAnchorPoint(0.5, 0.5)

local snd1=Sound.new("1.wav") dot1.sndchn=snd1:play(0,true,true)

local dots = {dot1}

local function onTouchesBegin(event) local dot = dots[event.touch.id] if dot then stage:addChild(dot) dot:setPosition(event.touch.x, event.touch.y) dot.sndchn:setWorldPosition(event.touch.x*audioScale, event.touch.y*audioScale) dot.sndchn:setPaused(false) end end

local function onTouchesMove(event) local dot = dots[event.touch.id] if dot then dot:setPosition(event.touch.x, event.touch.y) dot.sndchn:setWorldPosition(event.touch.x*audioScale, event.touch.y*audioScale) end end

local function onTouchesEnd(event) local dot = dots[event.touch.id] if dot and stage:contains(dot) then stage:removeChild(dot) dot.sndchn:setPaused(true) end end

local function onTouchesCancel(event) local dot = dots[event.touch.id] if dot and stage:contains(dot) then stage:removeChild(dot) dot.sndchn:setPaused(true) end end

stage:addEventListener(Event.TOUCHES_BEGIN, onTouchesBegin) stage:addEventListener(Event.TOUCHES_MOVE, onTouchesMove) stage:addEventListener(Event.TOUCHES_END, onTouchesEnd) stage:addEventListener(Event.TOUCHES_CANCEL, onTouchesCancel) </source>
