This visualizer was implemented using GDScript, responsible for the visual part of projectile curve. The actual projectile template is also provided.

Demo scenes include:

1. Third-person projectile: Player can aim and throw projectiles.
2. Top-down tower defense(paper ball fight): Target position is already known, throwers will launch projectiles exactly to that point. Certain heuristic(thrower can predict the possible target location at real-time) is implemented for both moving thrower and moving target, which makes it more difficult to dodge.
