I really need help right now… Been pulling my hair for a while
Ever since I downloaded the latest build of Corona (312) bad code has been exposed. Code that worked in previous versions of Corona due to bugs now don’t work, so I’ve been trying to fix it for 2 whole days… It’s the last thing I’ve got to fix before shipping my app so I realllly want to get this done, please I’d appreciate all help!

And this is the spawn enemy function:

local function choose1()
local choose = rnd(1, 2)
-- If satsen
if(choose == 1) then
if(ballSize \<= 8) then
enemyNumber = rnd(1, 3)
elseif(ballSize \> 8 and ballSize \<= 18) then
enemyNumber = rnd(3, 6)
end
enemy = display.newImage(""..enemyNumber..".png", rnd(228, 230), -140)
localGroup:insert(enemy)
worldGroup:insert(enemy)
-- Radius
if(enemyNumber == 1) then
enemySize = 4
enemy.class = "1"
elseif(enemyNumber == 2) then
enemySize = 5
enemy.class = "2"
elseif(enemyNumber == 3) then
enemySize = 6
enemy.class = "3"
elseif(enemyNumber == 4) then
enemySize = 7
enemy.class = "4"
elseif(enemyNumber == 5) then
enemySize = 8
enemy.class = "5"
elseif(enemyNumber == 6) then
enemySize = 9
enemy.class = "6"
end
-- Fysik
physics.addBody(enemy, { density=1.0, friction=0.3, bounce=0,
radius=enemySize, isSensor=true })
if(enemyNumber == 1) then
enemy:applyForce(0, rnd(3, 7), 0, 0)
elseif(enemyNumber == 2) then
enemy:applyForce(0, rnd(5, 9), 0, 0)
elseif(enemyNumber == 3) then
enemy:applyForce(0, rnd(7, 17), 0, 0)
elseif(enemyNumber \> 3 and enemyNumber \<= 5) then
enemy:applyForce(0, rnd(26, 56), 0, 0)
elseif(enemyNumber \> 5 and enemyNumber \<= 6) then
enemy:applyForce(0, rnd(35, 65), 0, 0)
end
-- Opacy
enemy.alpha = 0.7
-- Lägg in i grupp
enemyGroup:insert(enemy)
-- Ingen rotation

-- Is Collideable
enemy.isCollideable = true
local function enemyCollision(self, event)
if(event.phase == "began" and event.other.class == "enemyCleaner") then
self:removeSelf()
self = nil
elseif(event.phase == "began" and event.other.class == "eastWall") then
self:removeSelf()

end
return true
end
enemy.collision = enemyCollision
enemy:addEventListener("collision", enemy)
-- Slut på If satsen
end
end
local enemyTimer = performAfterDelay(0.3, choose1, 0, true) And again, if I remove the ‘return true’ from the enemyCollision-function, the simulator will crash on collision. But this time, with return true it works all the time
Thanks in advance! [import]uid: 14018 topic_id: 7813 reply_id: 27722[/import]
It crashes right on collision. If I remove everything that has anything to do with event.other and if i remove ‘ball:removeSelf() and ball = nil’ it works flawlessly… And if I don’t remove anything but just add a return true statement right before the end of the function it works to some degree… Sometimes the collision will work and sometimes it wont

you’re trying to create a new ball (and hence physics body) *inside* your collision function, i very much doubt that will work without crashes. you can’t change the physics system during a collision [import]uid: 6645 topic_id: 7813 reply_id: 27780[/import]
No I’m flagging it on collision and outside the collision function I’ve got an enterframe function checking the flag - creating a new ball… [import]uid: 14018 topic_id: 7813 reply_id: 27790[/import]
sorry, yes you are, I read it wrong [import]uid: 6645 topic_id: 7813 reply_id: 27809[/import]
i would do this …
[lua]local function collisionWatcher()
if(ball.hasHadCollision == true) then
– you need to add this line
ball.hasHadCollision=false – [/lua]
that stops it trying to run it more times than it needs to at least
i dont know if it will fix your problem but it definitely needs to be reset at some point. i know it does when you recreate your ball but i’m not sure if that is soon enough. if you want to put a zip on mediafire (or wherever) i will have a play at some point [import]uid: 6645 topic_id: 7813 reply_id: 27810[/import]
