Catch coin and increment variable

[Breno Pinheiro]

Hello, I am trying to create a game, using P2 Physics, that the user can catch coins. The problem is that when the user catch a coin, I need to increment a variable. If I use a code like this

        astronauta.body.collides(moedaCollisionGroup, function (astronauta, moeda) {

            moeda.sprite.kill();
            moedaspegas++;           
            exit;
                
        }, this);

The sprite of coin is hided, but the variable moedaspegas keeps being incremented. How can I do to the variable moedaspegas is incremented once?

moedaspegas+=1;

would it be that you need moeda.kill(); ?

The P2 Physics don´t have a method called kill. If I use the moeda.destroy(), the body of the coin is destroyed, but the sprite keeps showed.

I believe you need to use moda.sprite.destroy();  That should get rid of both the sprite and it's P2 body.

Otherwise, if you want to reuse the sprite later by reviving it, you could also wrap the code in an if(moda.sprite.alive) check.

moeda.sprite.alive works if I use the phaser in a browser game, but If I use in a cordova app, an error is showed saying that the propriety don't exist.

P2 has a quirk that sometimes you collide with a body that doesn't have a sprite, or doesn't know what it's sprite is.  I don't really know why this is, and the documentation says "if the p2 body was created without a sprite" but it still happens sometimes even if I know all the bodies are connected to sprites

That said, add a check to see if the sprite exists and it should fix this problem.  

 

if(moeda.sprite && moeda.sprite.alive)
