I plan to work on this

Planning sheet for this issue: https://docs.google.com/document/d/1w38R68yiIp-KqdV1nD71Aqwp-a25HfqR2ZnA47DeEbI/edit?usp=sharing
I propose adding an AnimationPlayerNode to the scene of the projectile. In this node there will be an animation "dissapear" modifying the property track "modulate" in order to simulate a blinking animation for the projectile. This animation will be looped because the dissapearing of the projectile is controlled by its script.
In adittion I propose modifying the projectile.gd script, as seen in the images, adding 4 new attributes, the animation player, time_passed, time_to_dissapear and is_dissapearing. Also there are going to be added some lines of code in the following functions: _ready(), _process() and _on_body_entered().
The behavior of the code is explained in the following images.

@Salonso928 excellent, please send a pull request and we can continue from there. Is hard to discuss code with images.
