Week 5 Challenge - Player Death Animation Please update with readme
First, we need to make a slight update to the logic in the game controller.
## Game Controller
This change ensures that our signal to kill the player can ONLY happen once, by checking that the health is above zero before issuing the signal.
```
func playerDamage():
#one can not kill what is dead....
if player.health >0:
player.health -= 20
#is the player dead?
if player.health <= 0:
#kill him
playerDeath.emit()
```
## Scene Manager
In the scene_manager, we have created a connection that listens for the game controller issuing the player death command:
`GameController.playerDeath.connect(killPlayer)`
We must change the `killPlayer` function. It will tell the player to die, but will then start a timer rather than immediatly reloading the scene.
```
func killPlayer():
# tell player to die - starts death animation
player.killPlayer()
if timer.is_stopped():
timer.start(4)
```
Notice that we only start the timer *if it is not already running*. Otherwise if the scene_manager happens to hear more `playerDeath` signals from the GameController, it will keep restarting the timer.
The `resetWorld` function is connected to the `timeout` event of the timer. It looks like this:
```
func resetWorld():
print("screne manager resetting world")
GameController.resetPlayer()
get_tree().reload_current_scene()
```
## Player
Lastly, the player code needs to ensure that the user can not do anything when their death animation is playing.
A simple way to do this is to create a boolean that simply keeps track of whether they are alive or not.
`var living = true`
We can then update the `killPlayer` function to check if the player is currently living and update the variable before calling the death animation.
```
func killPlayer():
print("kill the player")
if living:
living = false
#play death animation
playerSprite.play("death")
```
With the `living` variable set to false, we simply check the variable before doing *anything* in the `_physics_process` function.
```
func _physics_process(delta: float) -> void:
if living:
# Add the gravity.
if not is_on_floor():
velocity += get_gravity() * delta
.......and so forth....
```
When the timer ends and the scene reloads, all of these variables will be reset and the loop begins again.
