How do I view and manage the lifes/hearts of a player

Right now I simply have 5 sprites anchored on the players layer. But how can I remove one heart when the player dies? How do I know which one to remove? I know I could select by UID, but what if I want to have different amounts of starting lifes?

Any help would be greatly appreciated

There's different ways to go about it, the one i usually use a single sprite with different frames for the amount of hearts. First frame (which is frame 0) has no heart, frame 1 has 1 heart, etc. I set the animation speed to 0 then i set the frame to match my player's life variable.

This sadly limits the maximum amounts of hearts I can have to the size of my sprite :/

If at all possible I would like the lifes of the character to only be limited by the width of the screen (or a limitation I can set however I want).

But for the time being, a sprite with multiple frames seems a good idea

Why don't you just use a tiled background and set it's width according to the number of lives that you have

Not sure what you mean by this

This tutorial shows the method described by kraed

Another idea is to stay with your original method, but to answer the question

But how can I remove one heart when the player dies? How do I know which one to remove?

you can do:

Event

System: Pick sprite instance sprite.Count - 1

Action

sprite: Destroy

Assuming they are displayed in the order they were created in (might need to re-order them first).
