array problem

Games
#1

I think that the problem is with the array in my function:

local itens = require ( "itens" )  
  
-----------------  
 local a = 0  
 local greenPoof = {}  
 local objetos = {}  
-----------------  
  
-------------------------------//------------------------------  
  
function E\_bomb1Spawn(e)  
 a = a + 1  
  
 objetos[a] = itens.novoItem()  
  
 objetos[a] = greenPoof[a]  
  
 --physics.addBody( objetos[a], "dynamic", { density=1, bounce=0, friction=0.5 } )  
  
  
 hudGroup:insert( objetos[a] )  
  
 objetos[a].collision = onImageCollision  
 objetos[a]:addEventListener("collision", objetos[a])  
 instance2:addEventListener("collision", instance2)   
  
end

when i try to run my game I get this error:

 level1.lua:1740: ERROR: table expected. If this is a function call, you might have used '.' instead of ':'

and my line 1740 is:

 hudGroup:insert( objetos[a] )

anyone want to give a shot?

This looks weird right?

objetos[a] = itens.novoItem()  
  
objetos[a] = greenPoof[a]

I don’t know what novoItem() does, but maybe you meant:

greenPoof[a] = itens.novoItem()  
  
objetos[a] = greenPoof[a]

?

– Poof code below –
if poofTween then transition.cancel( poofTween ); end

greenPoof[a].x = self.x; greenPoof[a].y = self.y
greenPoof[a].alpha = 0
greenPoof[a].isVisible = true

local complete1 = function (e)
greenPoof[a]:removeSelf()
end

local fadePoof = function(e)
transition.to( greenPoof[a], { time=300, alpha=0, onComplete = complete1 } )
end
poofTween = transition.to( greenPoof[a], { time=100, alpha=1.0, onComplete=fadePoof } )

self.parent:remove( self )
self = nil
end

function E_bomb1Spawn(e)
a = a + 1

objetos[a] = itens.novoItem()
objetos[a].x = 150

greenPoof[a] = display.newImageRect( “imagens/bola.png”, 30, 30 )
greenPoof[a].alpha = 1.0
greenPoof[a].isVisible = false

gameGroup:insert( greenPoof[a] )

–physics.addBody( objetos[a], “dynamic”, { density=1, bounce=0, friction=0.5 } )

hudGroup:insert( objetos[a] )

objetos[a].collision = onImageCollision
objetos[a]:addEventListener(“collision”, objetos[a])
instance2:addEventListener(“collision”, instance2)

end
[/code]

in my game, when a object collide with the ground, he break up
and after 300 miliseconds he removeSelf… but my problem is to do this… what happen when 2 objects collide in the ground, the first object begin the transition to fade in and removeself, but when the second object collide, he stop the first objects removeSelf function
I try to make this “greenPoof” a array and set this to have a ID, one for each object… but i dont know why this isnt working

[code]a = a + 1

objetos[a] = itens.novoItem()
objetos[a].x = 150

greenPoof[a] = display.newImageRect( “imagens/bola.png”, 30, 30 )
greenPoof[a].alpha = 1.0
greenPoof[a].isVisible = false

gameGroup:insert( greenPoof[a] )

I cant see where you define hudGroup as a group [import]uid: 5354 topic_id: 10765 reply_id: 39342[/import]

#5

i just omit some code to not make my post more bigger… my problem isn´t in hudGroup and yes in greenPoof[a]

If you strip it down to just the code that is necessary I will have a look tomorrow.

From first read of the code I would use local inside the function when generating new objects / images so the object is unique and inside the scope of the function

then inserting it into an array or table

you cant use an array / a counter as removing the object will alter the makeup of the array

use table insert and #tableName to count the current number of objects in the array

im not sure I would use an array at all for this, I cant see where its needed

anyway off to pub, email me at the email address on www.coronaremote.com and I will have a look tomorrow [import]uid: 5354 topic_id: 10765 reply_id: 39348[/import]

#7

you want that I send you all my code to your check at this email? [import]uid: 23063 topic_id: 10765 reply_id: 39353[/import]

#8

Write a small amount of code that contains just enough code to run and demonstrate the bug. Don’t send all 1700+ lines of code. [import]uid: 5354 topic_id: 10765 reply_id: 39355[/import]

#9

ok but i will need to write the itens.lua too, for make the objects [import]uid: 23063 topic_id: 10765 reply_id: 39360[/import]
