Projectiles

Related images: Projectile images

In Team Fortress 2, certain weapons fire projectiles. Projectiles, unlike hitscan bullets, do not travel instantaneously across the map but rather at a preset speed and often subject to engine physics. This speed also differs between the weapons used to launch the projectile. Projectiles are not affected by Lag compensation, likely due to technical limitations surrounding the engine's physics applied on projectiles.

The Compression Blast ability of the Flamethrower and Degreaser can reflect all projectiles save for syringes. Once reflected they will switch ownership to the Pyro whom reflected the projectile (unless said projectile is a stickybomb -- in which case it is simply rolled along the ground), and deal Mini-Crit damage on enemies they hit. In addition, when colliding mid-air some projectiles may deflect opposing ones, or destroy them completely.

Hit Boxes

The hitboxes used for projectile weapons differ from those used for hitscan ones. Whereas the hitscan ones consist of several small rectangulars "wrapped" tightly around each class's model, the hitboxes for projectile weapons are larger, and consist of only one box that covers both the model and some of the space surrounding it. This is the reason why seemingly failed shots from projectile weapons (e.g. Huntsman) end up hitting their target.
