Hi valerio.innorta, try this approach, it works for me.

function onCollision( self, event )
        if ( event.phase == "began" ) then
                if( event.other.objectName =="enemy" ) then
                        self:removeSelf();
                        self = nil;
                        event.other:removeSelf();
                        event.other = nil;
--                              No need to remove the event listener, that is removed when you remove the object that is associated with it. Enterframe events must be removed manually though.
                end
        end
end

hey ... thanks a lot for your quick answer to the question! but the problem remains: my game is set

orientation =
{
default = "landscapeRight",
},

I'd like to bring up the enemy with a kind of transition from right to left, and also when my projectile is launched, the bullet passes over the enemy without touching it .. why? seen that the enemy is a physical object? I wait your answer thanks a lot =)

So your working on a left to right shooter, good one! my favorite type of shooter.

I realised I forgot to add how I deal with the Physics:

1	physics.addBody(enemy, { isSensor = true });

nothing to do ... applying to the projectile and the enemy is.Sensor = true, the two pass over without touching ... I am going crazy! I would also like to create a function that generates my enemies that come out right, but I can not do that! please help me

Hmmm, that is irritating, I had major problems with collisions when I started out too. Could you upload your game so far to a website and post the link here? It would be easier for me to take a look at.

I am, sorry for the delay but I worked on my game in a different way.
I created a SPRITE SHEET for my enemy, but I would like to have a random number of enemies that come at a random position on screen. Also I just can not understand how to function on COLLISION, all my attempts seem vain! I put my code, I hope you able to help =)

I spawn random enemies on a screen in the game I'm working on right now, so I can help you out there.

What you want to do first is create a function to spawn an enemy, say

local ufo = {} -- Use as array to store each ufo.
local numberUfos; -- Use to keep track of number of ufo's in array.
spawnUFO = function()
numberUfos = #numberUfos+1; -- indexing of arrays starts at 1. The # grabs the current size of the array. 
-- Display image, position, set scale etc.
ufo[numberUfos].myName = "ufo"; -- important for collision detection.
physics.addBody( ufo[numberUfos], { isSensor = true }); -- no physics properties are activated, but can be used to sense collisions.
 
-- You can prepare and play your sprite sheet here too.
end

Forgive me, my mistake not to tell you that my UFO is only the landscape background that moves! Unfortunately I changed my code so many times! my enemy is myAnim.
I created a sprite sheet of the enemy ... and now I'm trying to implement your code by modifying it according to my needs! I hope to be able to ADJUST the code .. I always wait your answers.
sorry again if I did not understand ...

There are errors where you add the player to the physics.

You spelled "kinematic" wrong. In your code it is "kynematic"
