Code: Select all

if ball_should_stick then
  ball.x = racket.x + 12
  ball.y = racket.y + 34
end
Didn't check your code.

In the first line of the example I posted, there's a conditional statement. It checks if expression between "if" and "then" evaluates to "true". If you have this variable set to "false" then it will not activate sticking code, if it's set to true - it will.

Thank you

If I add it it does not work the ball does not stick :

Code: Select all

 if  balle_should_stick and balle.colle == true  then
       balle.x = raquette.x + 12
       balle.y = raquette.y + 34
    
   end  
At the beginning of the code I put:
-- La balle
local balle = {}
balle.x = 420
balle.y = 550
balle.colle = false

The "balle_should_stick" is a made-up variable that you substitute with something on your own, it controls whether ball should stick or not. You have there "balle.colle" so you probably don't need that first one. Also since you never set it to anything, it evaluates to "false". You should just remove "balle_should_stick".

If I do that, it does not work I have more ball

Code: Select all

   if  balle.colle == true  then
       balle.x = raquette.x + 12
       balle.y = raquette.y + 34
    
   end
