i want to destroy the balls with touch !!

[rflorezablan]

i want to destroy the balls when i touch… this is my code (i am very noob)[code]
– add physics engine, start up the engine, and apply gravity
local physics = require(“physics”)
physics.start()
– Set gravity to act “down” (ie, toward the bottom of the device )
physics.setGravity (0, 9)
–set background image
local background = display.newImage( “background.jpg” )
–set ball to stage and position
local function spawnBall()
local ball =display.newImage(“bead2.png”)
ball.x = math.random ( 320 )
ball.y = -100
– turn ball into physics body
physics.addBody(ball,{bounce = 0.1 } )
end
timer.performWithDelay( 500,spawnBall,50)

–add floor image and position
local floor = display.newImage(“bar.png”)
floor.y = display.contentHeight/1.03
– turn floor into physics body
physics.addBody(floor,“static”) [import]uid: 179948 topic_id: 31552 reply_id: 331552[/import]

I’d definitely check out Dr. Rafael Hernandez’s video tutorials. It sounds like his "Orb Smasher game is similar to what you’re trying to do. Here it is:

He makes the function to destroy his orbs around 8 minutes in. I’d recommend watching the whole thing though.

Hope this helps!

Do you want to destroy the balls when you touch the screen?

If so you’d need to add event listeners to each ball when they are created.

i try to do it but didn’t work ,thank very much brandon
this is my code (sorry for the bad english i am from venezuela and i have 13 years old)
if you can tell me what is wrong i appreciate very very much

[code]-- add physics engine, start up the engine, and apply gravity
local physics = require(“physics”)
physics.start()
– Set gravity to act “down” (ie, toward the bottom of the device )
physics.setGravity (0, 9)

–add floor image and position
local floor = display.newImage(“bar.png”)
floor.y = display.contentHeight/1.03
– turn floor into physics body
physics.addBody(floor,“static”)

local function trackBalls (obj)
obj:removeSelf():
end

–set ball to stage and position
local function spawnBall()
local ball =display.newImage(“bead2.png”)
ball.x = math.random ( 320 )
ball.y = -100

– turn ball into physics body
physics.addBody(ball,{bounce = 0.1 } )
end

function ball:touch(e)
if(e.phase == “ended”) then
–remove the balls
trackBalls(self);
end

return true;

end

ball:addEventListener(“touch”, ball) ;

end

timer.performWithDelay( 500,spawnBall,50)

Hey, give this a shot…

  
-- add physics engine, start up the engine, and apply gravity  
local physics = require("physics")  
physics.start()  
-- Set gravity to act "down" (ie, toward the bottom of the device )  
physics.setGravity (0, 9)  
--set background image  
local background = display.newImage( "background.jpg" )  
   
--add floor image and position  
local floor = display.newImage("bar.png")   
floor.y = display.contentHeight/1.03  
 -- turn floor into physics body  
physics.addBody(floor,"static")  
   
local function trackBalls (obj)  
 obj:removeSelf()  
end  
   
--set ball to stage and position  
local function spawnBall()  
local ball =display.newImage("bead2.png")  
ball.x = math.random ( 320 )  
ball.y = -100  
   
-- turn ball into physics body  
physics.addBody(ball,{bounce = 0.1 } )  
  
 function ball:touch(e)  
 if(e.phase == "ended") then  
 --remove the balls   
 trackBalls(self);  
 end  
  
 return true;  
  
 end  
  
 ball:addEventListener("touch", ball) ;  
  
end   
  
timer.performWithDelay( 500,spawnBall,50)  
   

You had a " : " after obj:removeSelf() and an extra “end” in the middle of your spawnBall() function. It should be good to go now

Yeah - I’d agree with Brandon, code looks perfect apart from that.

Good luck with it! [import]uid: 163581 topic_id: 31552 reply_id: 126094[/import]
