   Hey all!

   So, here is what I'm doing. In the app I'm making, I have two different sets of objects. One keeps track of the players life. That I've already made, it's pretty straight forward with some sprite objects and setting labels. But there will be 4 other objects on the screen at the same time, 1 in each corner, that you can tap and it will change /the selected Player Objects health/. I can do the selected object part, simply make that a Bool variable for the object. The two things I am having trouble with is:

   When I select 1 player object, any previously selected objects should become unselected. How can I see which one's are selected or not?

   and:

   When I tap one of the objects in the corner to change the selected objects health, it should "find" which one is the selected one and then change it's health. How can I have it find which one it is? I'm not sure how I can pass around the objects so everything knows what's going on... help would be appreciated. If anything is unclear, I'll be glad to clarify. Thank you!

   You could store the objects in an array, and each frame loop through its elements (the player health objects) asking if they are selected, if one is, act accordingly.

   If you only have to check when they are tapped, loop when doing so instead.

   Hope i was clear!

   I am storing both sets of objects in arrays (The player objects and the Buttons (in the corners)). I looked through the prebuilt code that comes with cocos2D and so I'll start messing around with trying to get that to work.

   However, I could use some clarification on one thing. Basically, I want the players life to change when a button is pressed, (but the button is not the player object). Where should I put the code to say "When this button is pressed, search the list of Player objects, find the one selected and change it's life."

   Where would that code go?

   Thank you!

   you could have that either in your button class or in your main layer class, i think.
   If your buttons are a CCMenu when you add the items you can specify a target for the selector.

   You can place that code anywhere, just figure out which place makes more sense.
   If your buttons are a custom class it would make more sense to place the code inside that. But if you are just using a cmenu and you don't intent to subclass the menu items you would be fine by placing the code in your main class.
   Then the method that gets called should do the looping through the player objects array to see which one is selected.

   There is another method i think you could do this, instead of storing the objects in an array and looping to see which one is selected. that would be:

   1) Create an object that is a pointer to a player object.
   2) Make that object point to the last selected player object.
   3)When you press the button do the action on this pointer object.

   This assumes ONLY ONE of the player objects can be selected at a given momment
