  • In the game I'm working on, I have implemented a lives counter, showing the number of lives as a number on a corner of the screen. However, I'd like this lives cointer to be a row of sprites, starting at 5 and with the number of sprites decreasing as lifes are lost. How would something like this be implemented?

  • Try Construct 3

  • You want a function with a loop on a subevent that loops "player health times", and it creates a heart at position + (loopindex * spacing). The function also destroys all hearts before the loop

    On Function "hud_health" -> Destroy "heart"
    Repeat player.health times -> Create object "heart" at X + (loopindex * spacing), Y

You call the function whenever the player takes damage, collects a life and at the start of the layout

  • Let's say that you have 3 as capacity of life.

    Make a Global Variable named "Life"

    Set (LifeSprite) as your sprite life counter (Image you see as life)

    Add Instance Variable Number named "Index" to (LifeSprite) 

    Global Variable Number = "Life"

{Group : + Life}
*Compare variable "Life" > 0
          ------> Create Object (LifeSprite) (64, 64)
          ------> Set (LifeSprite) instance variable "Index" to 1

*Compare variable "Life" > 1
          ------> Create Object (LifeSprite) (128, 64)
          ------> Set (LifeSprite) instance variable "Index" to 2

*Compare variable "Life" > 2
          ------> Create Object (LifeSprite) (192, 64)
          ------> Set (LifeSprite) instance variable "Index" to 3

{Group: - Life}

*Compare variable "Life" < 3
          *Pick by comparison (LifeSprite.Index = 3)
                       --> LifeSprite [Destroy] or [Fade out]             (Note: Your choice if fadeout or destroy)
     
*Compare variable "Life" < 2
          *Pick by comparison (LifeSprite.Index = 2)
                       --> LifeSprite [Destroy] or [Fade out]             (Note: Your choice if fadeout or destroy)
     
*Compare variable "Life" < 1
          *Pick by comparison (LifeSprite.Index = 1)
                       --> LifeSprite [Destroy] or [Fade out]             (Note: Your choice if fadeout or destroy)

You might also want to set the layer of the sprite counter parallax to 0 and add an anchor behavior for your LifeSprite.
That's it. Happy Game making
