Class: Sound

Description

Sets the position of the listener in a 3D environment. 

Sound.setListenerPosition(x,y,z,vx,vy,vz,dx,dy,dz,ux,uy,uz)

  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

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)
