Help with Collision of spawned object(postion fixed) with objects that there are translating on screen
- by Amrutha
Hey guys I am creating a game using Corona SDK and so coding it in Lua.
So there are 2 separate functions,
To translate the hit objects and change their color when they are tapped
The link below is the code I am using to for the first function
http://developer.anscamobile.com/sample-code/fishies
Spawn objects that will hit the translating objects on collision. Alos on collision the spawned object disappears and the translating object bears a color(indicating the collision). In addition the size of this spawned object is dependent on i/p volume level. The function I have written is as follows:
--VOICE INPUT CODE
local r = media.newRecording()
r:startRecording()
r:startTuner()
--local function newBar()
-- local bar = display.newLine( 0, 0, 1, 0 )
-- bar:setColor( 0, 55, 100, 20 )
-- bar.width = 5
-- bar.y=400
-- bar.x=20
-- return bar
--end
local c1 = display.newImage("str-minion-small.png")
c1.isVisible=false
local c2 = display.newImage("str-minion-mid.png")
c2.isVisible=false
local c3 = display.newImage("str-minion-big.png")
c3.isVisible=false
--SPAWNING
local function spawnDisk( event )
local phase = event.phase
local volumeBar = display.newLine( 0, 0, 1, 0 )
volumeBar.y = 400
volumeBar.x = 20
--volumeBar.isVisible=false
local v = 20*math.log(r:getTunerVolume())
local MINTHRESH = 30
local LEFTMARGIN = 20
local v2 = MINTHRESH + math.max (v, -MINTHRESH)
v2 = (display.contentWidth - 1 * LEFTMARGIN ) * v2 / MINTHRESH
volumeBar.xScale = math.max ( 20, v2 )
local l = volumeBar.xScale
local cnt1 = 0
local cnt2 = 0
local cnt3 = 0
local ONE =1
local val = event.numTaps
--local px=event.x
--local py=event.y
if "ended" == phase then
--audio.play( popSound )
--myLabel.isVisible = false
if l > 50 and l <=150 then
--c1:setFillColor(10,105,0)
--c1.isVisible=false
c1.x=math.random( 10, 450 )
c1.y=math.random( 10, 300 )
physics.addBody( c1, { density=1, radius=10.0 } )
c1.isVisible=true
cnt1= cnt1+ ONE
return c1
elseif l > 100 and l <=250 then
--c2:setFillColor(200,10,0)
c2.x=math.random( 10, 450 )
c2.y=math.random( 10, 300 )
physics.addBody( c2, { density=2, radius=9000.0 } )
c2.isVisible=true
cnt2= cnt2+ ONE
return c2
elseif l >=250 then
c3.x=math.random( 40, 450 )
c3.y=math.random( 40, 300 )
physics.addBody( c3, { density=2, radius=7000.0 , bounce=0.0 } )
c3.isVisible=true
cnt3= cnt3+ ONE
return c3
end
end
end
buzzR:addEventListener( "touch", spawnDisk ) -- touch the screen to create disks
Now both functions work fine independently but there is no collision happening. Its almost as if the translating object and the spawn object are on different layers. The translating object passes through the spawn object freely.
Can anyone please tell me how to resolve this problem. And how can I get them to collide.
Its my first attempt at game development, that too for a mobile platform so would appreciate all help. Also if I have not been specific do let me know. I'll try to frame the query better :).
Thanks in advance.
