Class: SoundChannel

Description

Sets the position of the sound in a 3D world. 

SoundChannel:setWorldPosition(x,y,z,vx,vy,vz)

Parameters

x: (number) sound x coordinate
y: (number) sound y coordinate
z: (number) sound z coordinate optional
vx: (number) sound velocity x component optional
vy: (number) sound velocity y component optional
vz: (number) sound velocity z component 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 dot2 = Bitmap.new(Texture.new("2.png"))
dot2:setAnchorPoint(0.5, 0.5)

local snd1=Sound.new("1.wav")
dot1.sndchn=snd1:play(0,true,true)
local snd2=Sound.new("2.wav")
dot2.sndchn=snd2:play(0,true,true)

local dots = {dot1, dot2}

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)
