Hi how can i remove all objects with the same name, if i use:
local screenGroup = self.view
local randomBad3 = function()
badC3 = display.newImage("BCloud3-"..tostring(math.random(1, 12))..".png")
badC3.x = math.random (0, 450); badC3.y = -50-- -50
physics.addBody( badC3, { density=.3, bounce=0.3, friction=.3, radius=25, filter=badc3CollisionFilter } )
badC3.name = "BCloud3"
badC3.isSensor = true
badC3.rotation = math.random(-30,30) -- Rotate the object
trans5 = transition.to( badC3, { time= math.random(yForB3A, yForB3B), y=600, transition=easing.OutExpo } )
badC3.gravityScale = 0.0
local cleanup
cleanup = function()
if badC3 then
if badC3.y >590 then
badC3:removeSelf()
badC3 = nil
end
end
end
Runtime:addEventListener("enterFrame", cleanup)
end
randomBadC3 = timer.performWithDelay( math.random(1000, 5000), randomBad3, 0 )
--
if badC3 then
badC3:removeSelf()
badC3 = nil
end
it only removes the last spawned one, not all of them
Add all images into one group when you want to delete delete entire group.
for i=1,#maingroup do
if maingroup[i] then
maingroup[i]:removeSelf();maingroup[i]=nil
end
end
end

So, this is my horrible code for a little game I am making. It's kind of similar to Flee the Facility. In my game, the person who is the 'beast' should be able to drag a player when they are knocked out, but they can't. I tried adding a rope constraint to the ragdoll and the 'beast', but it just makes the beast have input lag and makes it's animations go weird.
I must note that the beast is a random player. I would try setting ownership of the ragdoll'd player to the grabber (which is the 'beast') but I need to set it to the server in order to change the state to Physics. I would use an event and a local script but I do not want this to be exploitable at all.
So, my question is: How do I attach a rope from a player to a ragdolled player without the non-ragdolled player lagging or having weird input lag and weird animations?
Like I said, I tried setting ownership but that wouldn't work as I need server ownership for setting the humanoid's state to physics. Just using takeOwnership() then ChangeState both on the same line wouldn't work so I had to put it in the while loop.
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
timer.performWithDelay(300,ulit,0)
Hi for some reason corona is giving me this error: attempt to index global 'backC' (a nil value)
local randomBackC = function()
backC = display.newImage("Cloud"..tostring(math.random(1, 4))..".png")
backC.x = math.random (30, 450); backC.y = -20
physics.addBody( backC, { density=2.9, friction=0.5, bounce=0.7, radius=24 } )
end
timer.performWithDelay( 500, randomBackC, 0 )
end
local function cleanup()
if backC.y >100 then
backC:removeSelf()
end
end
Runtime:addEventListener("enterFrame", cleanup)
any ideas of what is causing this?
backC may be already removed because of the Runtime:addEventListener("enterFrame", cleanup)
enterFrame will call the cleanup() over and over again, so you have to remove the enterFrame after you remove the backC and if you want to create multiple objects, make it local only to the function because it may cause referencing problem.
Like this
local randomBackC = function()
local backC = display.newImage("Cloud"..tostring(math.random(1, 4))..".png")
backC.x = math.random (30, 450); backC.y = -20
physics.addBody( backC, { density=2.9, friction=0.5, bounce=0.7, radius=24 } )
local cleanup
cleanup = function()
if backC then
if backC.y >100 then
backC:removeSelf()
backC = nil
Runtime:removeEventListener("enterFrame", cleanup)
end
end
end
Runtime:addEventListener("enterFrame", cleanup)
end
timer.performWithDelay( 500, randomBackC, 0 )
Hi my objects are not removing after leaving the scene, i have tried to purging and removing the scene, but the objects will just keep on spawning in a other scene?
local badclout1 = {}
local bad1Group = display.newGroup()
local function spawnBC1()
local badclouts1 = display.newImage("BCloud1.png")
badclouts1.x = math.random(0, _W)
physics.addBody( badclouts1, "dynamic", { density=.1, bounce=.1, friction=.2, radius=45 } )
badclouts1.name = "BCloud1"
badclouts1.bodyType = "kinematic"
badclouts1.isSensor = true
badclouts1.y = math.random(-100, -50)
badclouts1.index = #badclout1 + 1
bad1Group:insert(badclouts1)
badclouts1.rotation = math.random(-10,10) -- Rotate the object
badclouts1:setLinearVelocity(0, math.random(speeda1, speedb1)) -- Drop down
badclout1[badclouts1.index] = badclouts1
tmrSpawn1 = timer.performWithDelay(math.random(spawna, spawnb), spawnBC1)
return badclouts1
end
tmrSpawn1 = timer.performWithDelay(math.random(1000, 10000), spawnBC1)
local function removeBomb()
for i, v in pairs(badclout1) do
if badclout1[i].y >1000 then
badclout1[i]:removeSelf()
badclout1[i] = nil
end
end
end
Runtime:addEventListener("enterFrame", removeBomb)
is there something in my code that keeps it on the screen ?
You need to cancel your performWithDelay function using timer.cancel(tmrSpawn1). Because you're calling it recursively, it will just keep going until you cancel it.
I have been modifying code from the memory match game to use scenes, sounds, and a 2d table. Adding the scenes has been the hard part. I have it set up to randomly select items from my 2d table. Load those into a temporary table, shuffle them shuffle(), then boardSet(); to load their sounds and place them on the screen. Basically after the game is over I want the scene to reload or go back to the menu to start again. Selecting random data{} elements over and over.
I have tried returning to the menu, or going to a duplicate scene however I can't seem to correctly unload the objects created by my 2d array, as I can't properly add each item into a display group. I have tried everything I can think of. Right now my game loop is setup to add the play again btn that I want to restart the game after one match is found.
This link was a start in the right direction I believe with information about dealing with tables and groups. I still don't know how to cycle thru my 2d table to include everything in a group and then properly unload it.

Yeah, this is simple.
here is an example(assuming that you have implemented storyboard)
function scene:createScene(event)
screenGroup = self.view
local image = display.newImage("image.png")
screenGroup:insert(image)
end
Now everything will go fine :)
Add all the display objects to a group.local myGroup = display.newGroup();
local img = display.newImage("yourimage.png");
myGroup:insert(img);
For example
If you follow this method, all display objects will not be flushed out of memory when you change the screen.
When using corona storyboard you need to add display objects to the group. For example you would need to add all of your display objects into screenGroup in order for them to be removed when you change scenes.
