I used physics.pause() and physics.start() , it works but my problem is that one function keeps displaying an object at the bottom and when I resume the game, those object are compiled and all of them enter screen at once. I hope someone can help me.
here's my code:
local isPaused = false
function pausePhysics( event )
if "began" == event.phase then
if isPaused == false then
physics.pause(lobo)
isPaused = true
timer.pause(countDownTimer)
local decide = display.newImage("wood.png")
decide.x = display.contentWidth*0.5
decide.y = display.contentHeight*0.5
local yes
local no
local function oo()
if score == 0 then
onBackBtnRelease()
elseif score >0 and score <=10 then
GameOver1()
elseif score >10 and score <=20 then
GameOver2()
else
GameOver3()
end
end
yes = widget.newButton
{
defaultFile= "yes.png",
width=100, height=50,
onRelease = oo
}
yes.x = display.contentWidth*0.3
yes.y = display.contentHeight - 200
local function hindi()
if isPaused == true then
physics.start()
isPaused = false
timer.resume(countDownTimer)
display.remove(decide)
decide = nil
display.remove(yes)
yes = nil
display.remove(no)
no = nil
end
return true
end
no = widget.newButton
{
defaultFile= "no.png",
width=100, height=50,
onRelease = hindi
}
no.x = display.contentWidth*0.7
no.y = display.contentHeight - 200
sceneGroup:insert(decide)
sceneGroup:insert(yes)
sceneGroup:insert(no)
return true
end
end
end
local function tapos(event)
if (event.phase == "began") then
physics.addBody(backBtn, "static")
end
end
Runtime:addEventListener("enterFrame", backBtn)
backBtn:addEventListener("touch", pausePhysics)
local function ulit()
local mRandom = math.random
local balloon = { ("blue.png"), ("green.png"), ("red.png"), ("orange.png"), ("pink.png"), ("violet.png"), ("yellow.png"), ("blue2.png"), ("green2.png"), ("red2.png"), ("orange2.png"), ("pink2.png"), ("violet2.png"), ("yellow2.png") }
local lobo = display.newImage( balloon[mRandom(10)], mRandom(30,270), mRandom(550,650) )
physics.addBody( lobo, { density=0.1, friction=2.0, bounce=0.0, velocity=-40, isSensor=true } );
end

i have a question with corona (LUA), at the moment im showing interstitial ad when tap button occurs. I have this and its working (sometimes takes like 5-10-15 seconds to load and ad, i dont know why:
local ads = require("ads")
local interstitialAppID = "ca-app-pub-xxxxxxxxxx/xxxxxxxx21"
local testMode = true
local adProvider = "admob"
local function adListener( event )
if ( event.isError ) then
print ( "Error en el anuncio!", msg )
elseif ( event.phase == "loaded") then
print ( "Anuncio cargado!", msg )
elseif ( event.phase == "shown") then
print ( "Cargando nuevo anuncio!", msg )
ads.load ("interstitial", { appId = interstitialAppID, testMode = isTestMode } )
end
end
ads.init("admob", interstitialAppID, adListener )
ads.load ("interstitial", { appId = interstitialAppID, testMode = isTestMode } )
-- INTERSTITIAL AD
local function Adinterstatial( self, event )
ads.show( "interstitial", { appId = interstitialAppID, testMode = isTestMode
} )
end
local test = display.newImageRect( "Lore/0.png", 50, 50 )
test.x = 150
test.y = 150
test.tap = Adinterstatial
test:addEventListener( "tap" )
I want to do this for example: every 20 taps (on all the app) shows an interistitial ad.
Is this possible?
How i can do it?
Thanks.
You can add a Runtime tap event. This will get all taps on the screen, it does not matter where or what object was tapped. For example:
local numTaps = 0
local function countTaps()
numTaps = numTaps + 1
if numTaps % 20 == 0 then
-- Show the add here.
end
end
Runtime:addEventListener("tap", countTaps)
The % gets the remaindeer of the division between numTaps and 20. This means that it will be 0 every 20 taps.
I'm trying to make a game in Corona SDK where a player runs and survives through obstacles by either jumping over them or killing them using bullets. The problem is that the game ends even if the player fires the bullet. But it should be over only if the player collides with the obstacles.
This is my code till now!!

You need to ask a specific question, what you have said is quite vague. Does the game end each time the player fires the bullet? Also you should consider migrating from storyboard to composer.
I'm a beginner in Corona developping and i've to problem to identify the collision between 3 objects. In fact, this is my code :
The first object is my player :
player = display.newImageRect("ballon.png", 150,170 )
player.anchorX = 0.5
player.anchorY = 0.5
player.x = display.contentCenterX - 450
player.y = display.contentCenterY+250
physics.addBody(player, "static", {density=0.1, bounce=0.1, friction=0.1,})
player.myName="player"
screenGroup:insert(player)
The second object is created within a function :
function addWindSlow(self,event)
height = math.random(display.contentCenterY - 200, display.contentCenterY + 200)
windslow = display.newImage( "wind-neg.png")
windslow.x = display.contentWidth
windslow.y = height
windslow.speed = 4
windslow.myName="windslow"
physics.addBody(windslow, "static", {density = 0.1, bounce = 0, isSensor = false})
elements:insert(windslow) end
function addWindFast(self,event)
height = math.random(display.contentCenterY - 200, display.contentCenterY + 200)
windfast = display.newImage( "wind-pos.png")
windfast.x = display.contentWidth
windfast.y = height
windfast.speed = 4
windfast.myName="windfast"
physics.addBody(windfast, "static", {density = 0.1, bounce = 0, isSensor = false})
elements:insert(windfast) end
And finally, the thirth object is the same but called "addWindFast() with a different image"
So i would like to know once my player is on collision with the windslow, i need to do an action... and if it's the object windfast, another action. That's my code :
function onCollision( event )
if ( event.phase == "began" ) then
if event.other.windslow and event.other.isVisible==true then
print("windslow has been touch !")
end
end
end
I found something about the pre-collision, I'll use it once i got the information how to "identify" the object...I'll need to prevent the collision and avoid it if the player is going to touch the windfast or windslow.
We thank you for all dude !
It looks like windslow and windfast are defined outside of onCollision event handler so you should compare to those:
function onCollision( event )
if ( event.phase == "began" ) then
if event.other == windslow and event.other.isVisible==true then
print("windslow has been touch !")
end
if event.other == windfast and event.other.isVisible==true then
print("windfast has been touch !")
end
end
end -- (missing from your post but probably in your code)
The above assumes that you have registered for collision events on your player. You could also register a different collision handler on each wind:
windslow:addEventListener("collision", onCollisionSlow)
windfast:addEventListener("collision", onCollisionFast)
In that case the two collision handlers could just check if event.other == player. The advantage of that is you are separating the code for each one. You could of course do the same with your player handler:
function onCollisionSlow(other)
print('collided with slow')
end
function onCollisionFast(other)
print('collided with fast')
end
collisionHandlers = {
[windslow] = onCollisionSlow,
[windfast] = onCollisionFast,
}
function onCollision( event )
if ( event.phase == "began" ) then
collisionFunc = collisionHandlers[event.other]
if collisionFunc ~= nil and event.other.isVisible then
collisionFunc(event.other)
end
end
end
You could identify the other object with the myName property you've specified.
For example:
function onCollision( event )
if ( event.phase == "began" ) then
if (event.other.myName == "windslow" and event.other.isVisible==true) then
print("windslow has been touched!")
elseif (event.other.myName = "windfast" and event.other.isVisible==true) then
print("windfast has been touched!")
end
end
I am doing a game in corona SDK, but I have this little problem.
I have a menu with a button. If I press it, it sends me to the first level of my game.
When I pass the final level, the game return me to the menu. Bur, if I start playing the first again, my images doesn´t appear.
The images are balls, and to pass the level, you have to eliminate all the balls. To do this, I use:
ball:removeSlef()
ball = nil
But, I don´t think that this is the problem, because I eliminate this lines, and it doesn´t work.
The images are create in scene:createScene function, and insert in the Group.
I short the code of the first level to be understood.
local storyboard = require( "storyboard" )
local scene = storyboard.newScene()
local physics = require "physics"
physics.start(); physics.pause()
physics.setGravity( 0, 0 )
local cont = 0
local bur = {}
function eliminar1( event )
if (cont == 0) and (event.phase == "began") then
event.target:removeSelf()
bur[1] = nil
cont = cont + 1
end
end
function eliminar2( event )
if (cont == 1) and (event.phase == "began") then
bur[2]:removeSelf()
bur[2] = nil
cont = cont + 1
end
end
function eliminar3( event )
if (cont == 2) and (event.phase == "began") then
bur[3]:removeSelf()
bur[3] = nil
storyboard.gotoScene( "levels.1.level2" )
end
end
function scene:createScene ( event )
local screenGroup = self.view
for i = 1,3 do
bur[i] = display.newImage("irudiak/"..i..".png")
bur[i]:translate(math.random(0,280), math.random(0,400) )
physics.addBody( bur[i], {bounce = 0.3 } )
bur[i]:setLinearVelocity(math.random(-50,50), math.random(-50,50) )
screenGroup:insert(bur[i])
end
bur[1]:addEventListener("touch", eliminar1)
bur[2]:addEventListener("touch", eliminar2)
bur[3]:addEventListener("touch", eliminar3)
end
function scene:enterScene( event )
local screenGroup = self.view
physics.start()
end
function scene:exitScene( event )
local screenGroup = self.view
physics.stop()
end
function scene:destroyScene( event )
local screenGroup = self.view
package.loaded[physics] = nil
physics = nil
end
return scene
createScene is ran only first time when you gotoScene. Every next time only willEnterScene and enterScene are played. To play createScene again you have to remove it (storyboard.removeScene() I guess). Or you can move some stuff you need to willEnterScene.
