Get reference a child in a group+collision+Arcade system

[sebamawa]

Hello all!

 

First. excuse me for my english.

 

I need to get a reference to child of a group, this in the collide function of Arcade system.

 

Example:

function update(){      collide(spritePlayer, groupPlatforms, collideCallback, processCallback, callbackContext);}I will think do some this:function collideCallback(){       //the problem is  I have no functions to retrieve the child of the groupPlatforms (I have getAt(index) and getIndex(child) for example)}

Any help is appreciated.

the solution is simple
 

function collideCallback(_player, _groupPlatforms){     var yourChild = groupPlatforms.getAt(number);}

the _groupPlatforms refers to groupPlatforms and getAt "returns The child that was found at the given index. If the index was out of bounds then this will return -1."

All you need to know on which position your child is.
number => child position in Array (example 0)

Thanks Sam,

 

But, the problem is that I don't know the index of the child. 

 

Is possible obtain a reference to child in a collision, without know the index?

 

Regards,

 

Edit: Here, the solution (found in the forum):

Thanks all,

yeah that's simply :
 

function collideCallback(_player, _collidingChild){    }

my bad, you can just put the reference in, and the system will detect the collision of the child of that group that collides.
