Collision trouble

Games
#1

i have search in corona’s forum and i have post there about this but seems anyone know what are wrong :S
i want to check collision only for 2 objects

local onImage1Collision = function ( self, event )  
 print ( "bomba2" )  
 if( event.target.type == "bomba" and event.other == "cauldron" ) then  
 score.setScore (score.getScore()+5)  
 print ( "bomba" )  
 end  
  
 if podeSlow then  
 slowScreen = timer.performWithDelay(10,SlowScreen,1)  
 end  
  
 -- Poof code below --  
 if poofTween then transition.cancel( poofTween ); end  
  
 greenPoof.x = self.x; greenPoof.y = self.y  
 greenPoof.alpha = 0  
 greenPoof.isVisible = true  
  
 local fadePoof = function()  
 transition.to( greenPoof, { time=100, alpha=0 } )   
 end  
 poofTween = transition.to( greenPoof, { time=100, alpha=1.0, onComplete=fadePoof } )  
  
  
 self.parent:remove( self )  
 self = nil   
 end

this is my code in collision, i have put .type for ground and bomb that will down from heaven… my i dont know why this part dont work, even print dont show in terminal confirming that this part dont work:

 if( event.target.type == "bomba" and event.other == "cauldron" ) then  
 score.setScore (score.getScore()+5)  
 print ( "bomba" )  
 end

if you know where i’m wrong

by the way:

 caldeirao = display.newImage ( "caldeirao.png", 248, 86 )  
 caldeirao.x = 260; caldeirao.y = 280  
 caldeirao.type = "cauldron"

(my “ground”)

 local E\_bomb1  
 local index = math.random( 1, #imagens )  
  
  
 E\_bomb1 = display.newImage ( imagens[index] )  
 E\_bomb1.x = math.random( 20, 460 )  
 E\_bomb1.y = math.random( -120, -10 )  
 E\_bomb1.xScale = 1  
 E\_bomb1.yScale = 1  
 E\_bomb1.type = "bomba"  
 physics.addBody( E\_bomb1, "dynamic", { density=1, bounce=0, friction=0.5 } )

(my bomb that will down and collide with cauldron) [import]uid: 23063 topic_id: 9992 reply_id: 309992[/import]

It looks like your condition is incorrect. You have:

if( event.target.type == "bomba" and event.other == "cauldron" ) then  
 score.setScore (score.getScore()+5)  
 print ( "bomba" )  
end

Instead of: (changed event.other to event.other.type)

if( event.target.type == "bomba" and event.other.type == "cauldron" ) then score.setScore (score.getScore()+5) print ( "bomba" ) end [import]uid: 49205 topic_id: 9992 reply_id: 36468[/import]

#3

nope… still not working =T

[code] if index == 12 then E_bomb1.postCollision = onImage12Collision end

hudGroup:insert( E_bomb1 )
E_bomb1:addEventListener( “postCollision”, E_bomb1 )
[/code]

if this helps…

anyone? [import]uid: 23063 topic_id: 9992 reply_id: 36470[/import]

#4

You have another typo.

onImage12Collision is called onImage1Collision in your original post. [import]uid: 49205 topic_id: 9992 reply_id: 36471[/import]

#5

sorry but i just copy the last… i have 12 collision for my 12 itens and images

 if index == 1 then E\_bomb1.postCollision = onImage1Collision end  
 if index == 2 then E\_bomb1.postCollision = onImage2Collision end  
 if index == 3 then E\_bomb1.postCollision = onImage3Collision end  
 if index == 4 then E\_bomb1.postCollision = onImage4Collision end  
 if index == 5 then E\_bomb1.postCollision = onImage5Collision end  
 if index == 6 then E\_bomb1.postCollision = onImage6Collision end  
 if index == 7 then E\_bomb1.postCollision = onImage7Collision end  
 if index == 8 then E\_bomb1.postCollision = onImage8Collision end  
 if index == 9 then E\_bomb1.postCollision = onImage9Collision end  
 if index == 10 then E\_bomb1.postCollision = onImage10Collision end  
 if index == 11 then E\_bomb1.postCollision = onImage11Collision end  
 if index == 12 then E\_bomb1.postCollision = onImage12Collision end  
  
 hudGroup:insert( E\_bomb1 )  
 E\_bomb1:addEventListener( "postCollision", E\_bomb1 )

You should only have collision method for all of your images.

In the collision method self.target will be the image you want.
[lua]local onImage1Collision = function ( self, event )

end[/lua]

Here’s an example from my code. (I’m removing some parts that are irrelevant to your situation)

 function spawnExit(x, y)  
 function exitCollision(self, event)  
 if event.other.name == "player" then  
 --end the game  
 end  
 end  
 local exit = display.newImage("images/objects/exit.png")  
 exit.name = "exit"  
 physics.addBody(exit, "static")  
 exit.collision = exitCollision  
 exit:addEventListener("collision", exit)   
 end

In another part of my program, I can call the spawnExit function and it will create an exit that has exitCollision as it’s collision method. No matter how many exits I make, this code will work. [import]uid: 49205 topic_id: 9992 reply_id: 36474[/import]

i dont know if i get it… i will show you my code and i will say to you what i dont to do in my game… my game will be of catch itens that will drop from heaven for do that you will need to use acelerometer to move a cauldron side to side to get them

sorry but i cant hide the code and i think you need look all to undersand what I wanted to say

disregard the methods that are initialized with “–” i try to hide wall in my text but didnt work =T [import]uid: 23063 topic_id: 9992 reply_id: 36480[/import]

#9

Ok, I’m understanding what you’re trying to do a bit more now.

Your problem might be that you are not adding a collision event listener to your caldeirao object. Also the first parameter passed to the event listener should be “collision” rather than “postCollision”

--for the E\_bomb1  
E\_bomb1.collision = onImage1Collision   
E\_bomb1:addEventListener("collision", E\_bomb1)  
-- For the caldeirao  
caldeirao:addEventListener("collision", caldeirao)

Let me know if that works. [import]uid: 49205 topic_id: 9992 reply_id: 36482[/import]

#10

still not workign… in caldeirao.collision

i need to make a different collision code right? [import]uid: 23063 topic_id: 9992 reply_id: 36483[/import]

#11

No you don’t need to. Only one of the objects needs a postCollision method. [import]uid: 49205 topic_id: 9992 reply_id: 36487[/import]

#12

Is the onImage1Collision function being called? [import]uid: 49205 topic_id: 9992 reply_id: 36488[/import]

#13

yea but still not working the

if( event.target.type == "bomba" and event.other.type == "cauldron" ) then score.setScore (score.getScore()+5) print ( "bomba" ) end

=T [import]uid: 23063 topic_id: 9992 reply_id: 36489[/import]

#14

Ahh! I just figured it out.

It should be:

if( self.type == “bomba” and event.other.type == “cauldron” ) then [import]uid: 49205 topic_id: 9992 reply_id: 36490[/import]

#15

sorry disappoint you but… still not working here :X
but thank you for your try [import]uid: 23063 topic_id: 9992 reply_id: 36491[/import]

#16

Can you print out self.type and event.other.type and see what they are? [import]uid: 49205 topic_id: 9992 reply_id: 36492[/import]

#17

that is the problem the print ( event.other.type ) is printing NIL
any idea? i have show you all my code and i have set caldeirao.type = “cauldron”

i have do that wrong? :S [import]uid: 23063 topic_id: 9992 reply_id: 36493[/import]

#18 
 if caldeiraoMenor == false and caldeiraoMaior == false then  
 caldeirao = display.newImage ( "caldeirao.png", 248, 86 )  
 caldeirao.x = 260; caldeirao.y = 280  
 caldeirao.type = "cauldron"  
 end  
  
  
 if caldeiraoMenor == true and caldeiraoMaior == false then  
 caldeirao = display.newImage ( "caldeirao.png", 100,86 )  
 caldeirao.x = 260; caldeirao.y = 280  
 end  
  
  
 if caldeiraoMenor == false and caldeiraoMaior == true then  
 caldeirao = display.newImage ( "caldeirao.png", 360,86 )  
 caldeirao.x = 260; caldeirao.y = 280  
 end

Are you sure the first if statement is being called? Because if it’s not (and one of the other two is) then the type will be nil [import]uid: 49205 topic_id: 9992 reply_id: 36497[/import]

#19

yea this is it
that is the problem :D:D:D

thank you very much =D
really [import]uid: 23063 topic_id: 9992 reply_id: 36501[/import]

#20

hm…
i only have sucess in first collision with the cauldron

collision before the event.other.type is changing to nil again oO
and i dont have a variable that to this

oh man… >.< [import]uid: 23063 topic_id: 9992 reply_id: 36502[/import]
