Cannon Projectile Behavior · 1.20.1
Cannon crafting guide · Weapon overhaul
AoA 3.7.1 / Minecraft 1.20.1: all 50 registered cannons, 41 referenced projectile classes. This is a released-class census, not captured native flight. It exists to prevent an upgrade from accidentally flattening different weapons into one generic cannon behavior.
Important differences to preserve
The projectile gravity method is not uniformly 0.1. Ghoul Cannon uses 0.05; several specialist projectiles use 0.015, 0.06 or 0.075. Fifteen projectile classes inherit BaseBullet’s zero-return method. A zero gravity return does not prove a motionless projectile, a hitscan attack or absence of other movement logic. Constructor velocity, drag, update methods, collision and server behavior still require separate inspection.
Five cannon weapon classes inherit their projectile factory directly from BaseCannon. The other 45 declare a factory. This census verifies those direct superclass relationships rather than assuming all missing methods resolve to the same class.
Projectile-class distribution
Counts below count unique projectile classes, not weapons; several weapons can share a projectile.
| Resolved gravity-method return | Unique projectile classes |
|---|---|
| 0 | 15 |
| 0.015 | 4 |
| 0.05 | 3 |
| 0.06 | 2 |
| 0.075 | 2 |
| 0.1 | 15 |
These values are game-code parameters, not metres per second squared or a measured travel arc.
Every cannon and its projectile
Sprites are the actual released item images. Profile links lead to weapon-specific research where available. “BaseBullet inherited” means the direct projectile superclass supplies the zero-return method; it does not mean the entire projectile behavior is identical.

Upgrade regression requirements
- Match each original projectile class and inherited method before choosing an upgraded visual.
- Capture original travel, fall, impacts and lifetime in the target release; separate native footage from concept art.
- Preserve collision/hitbox and damage semantics unless a gameplay-bearing attachment explicitly changes them.
- Check velocity, drag, per-tick custom movement, lifetime, piercing, split/spawn behavior and server ownership; this gravity table alone is insufficient.
- Use time-based visual particle budgets while retaining original effect identity, rather than coupling emissions to render frequency.
- Test multiplayer, low/high frame rates, slow server ticks, unloaded chunks and relevant compatibility targets.
Evidence and limits
Released class census and hashes records every factory method, weapon-class hash, projectile-class hash and resolved gravity owner. Reproducible extraction and tests requires the separately obtained official AoA JAR and a Java development kit. It does not bundle the mod.
The extractor only accepts simple two-instruction float-return overrides for this summary. More complex methods must be inspected instead of taking the first constant as a result. The baseline is one pinned release; newer versions remain separate work. Native testing is not inferred.
