Projectile movement

Types of projectile movement

Straight

The vast majority of projectiles in the Bloons TD series and Bloons Supermonkey series travel in a straight line from their point of emission. The movement of these projectiles is typically dictated by their projectile speed, or how fast the projectile moves, and projectile lifespan, which dictates how long the projectile lasts before expiring on its own.

Curved

Some projectiles, most notably the Boomerang Monkey's boomerangs, follow a curved path back to the source.

Kylie Boomerang's projectiles use the same system, except with zero width, causing it to travel forwards and backwards in a straight line.

Seeking

Seeking projectiles are capable of rotating in mid-air to face towards Bloons,

The behaviour of seeking projectiles is typically defined by three variables:

• Turn speed: how quickly the projectile can rotate in mid-air. In the Flash versions of BTD5, Battles, and BMC, it is measured in radians per second, while in the mobile versions of those games, Bloons TD 6, Bloons Adventure Time TD, and Bloons TD Battles 2, it is measured in degrees per second. The faster the turn speed, the more "aggressive" and accurate the seeking is.
• Seek angle: the radius in front of the projectile in which it can lock onto a Bloon. Some projectiles have a seek radius of 360°, allowing them to target Bloons from any angle, while others can only target Bloons within a cone in front of the projectile.
• Seek distance: how far away the projectile can target a Bloon from. Some projectiles have infinity seek distance, allowing them to target Bloons from any distance, while others can only target Bloons within a certain range of the projectile.

The "aggressiveness" of a seeking projectile is dictated by the combination of these variables; Neva-Miss Targeting's fast projectile speed, turn speed, infinite seek angle and distance, and long lifespan give it its "aggressive" seeking style, while Apache Dartship's missiles' slower projectile speed, turn speed, limited seek angle and distance, and shorter lifespan gives them a much "weaker" seeking style.

Instant

Instant projectiles snap to the target instantaneously upon being shot. This type of movement was introduced in the Flash version of Bloons TD 5 with the Sniper Monkey and is typically used by gun attacks, such as Captain Churchill's machine gun and Agent Jericho's pistol. These kinds of projectiles are invisible and are typically only able to hit the target, ignoring everything else and being unaffected by pierce buffs.

In the mobile versions of BTD5, Battles, and BMC, instant attacks do not use projectiles at all; the attacks themselves simply deal damage to the target directly.

Bouncing

Bouncing projectiles are similar to seeking projectiles in that they can change their angle mid-air, except they can only change their angle upon colliding with a Bloon, causing them to ricochet from Bloon to Bloon in a line. This type of movement was introduced in the Flash version of BTD5 with Glaive Ricochet and is used prominently by the Boomerang Monkey's upgrades and Quincy. Bouncing projectiles have a limited range in which they can target Bloons, but can target from any angle.
