Gravity Blaster · launch yourself, clear nearby hostiles

Released baseline: Minecraft 1.20.1 / AoA 3.7.1. Upgrade status: concept and released-file study; no native upgraded weapon accepted.

This Spirit-powered utility blaster launches its user upward while pushing and applying an energy attack to nearby hostile mobs. Its identity is a movement-and-space-clearing burst, not a conventional projectile gun. The tooltip says “Blasts the user upwards.”

Original contract

Field	Released value or meaning
Registry ID	aoa3:gravity_blaster
Stored base damage	4.0, passed into the energy-attack helper for each selected mob
Durability	600
Stored firing delay	1 tick; not proof of effective spam frequency
Base charge field	1 tick in the inherited constructor
Base Spirit cost	120.0, before inherited modifiers/exemptions
Target volume	Shooter bounding box inflated by 2 on X/Z and 0 on Y
Target filter	Released HOSTILE_MOB: Enemy interface only
Target push helper	pushEntityAway(shooter, mob, 0.5f)
User movement	Adds (0, 2, 0) to velocity, and marks the entity for motion synchronization
Sound	ITEM_GRAVITY_BLASTER_FIRE
Flight projectile	None created by this firing override

The target box is not a two-block sphere or an aim ray. The unchanged Y extent, entity bounding boxes, walls and vertical separation all matter. The override does not show a line-of-sight test. Do not promise a fixed jump height: starting velocity, collision, gravity, terrain and other mods determine the result. No fall-damage immunity is granted in this method.

Important source-version difference

The named-source comparison at commit 85d6beba07e3a09032834dcf79b5a01f411092c3 adds angry NeutralMob entities to its hostile predicate. The pinned released 1.20.1 class does not. The release's predicate tests Enemy only. Preserve that distinction instead of silently changing targeting while upgrading visuals.

Push is not Vortex Blaster's helper

The released helper adds the unnormalized center-to-target position difference to existing target velocity, scaled by (1 − min(knockback resistance, 1)) × 0.5. Full resistance returns without applying that push. It does not use the same doScaledKnockback path as Vortex Blaster, so do not copy Vortex's specific event/attribute behavior onto this weapon. The separate energy attack still runs after the push call; blocking the push alone is not proof that damage is blocked.

Acquisition: released infusion recipe

Use the AoA infusion system with a Blaster Frame as the input and four Floating Stones as ingredients to produce one Gravity Blaster. This is the shipped aoa3:infusion recipe, not a standard crafting-table grid. Other progression prerequisites should be followed in the version-specific infusion tutorial.

Infusion input	Ingredients	Result
1 × Blaster Frame	4 × Floating Stone	1 × Gravity Blaster

Upgrade concept

The concept retains the compact silver/charcoal tool-like silhouette, broad drum, dark horizontal bands and enclosed rear handle. A restrained blue distortion field gives the imaginary Spirit mechanism depth. The inset pixel-style motif is part of the generated concept; the exact released sprite is shown separately above.

• Default pulse: drum rings compress, a brief pressure ripple appears, then rings relax. Tie this to a server-accepted use, with no cosmetic duplicate attack.
• Inspect: the chamber briefly reveals a suspended miniature distortion, then seals. Movement, firing, inventory changes and weapon swaps must interrupt safely.
• Lift governor attachment: proposed controllable low/high lift presets with clearly displayed effective Spirit cost. This changes gameplay and needs explicit balancing and server authority.
• Grounding collar: proposed nearby-space-clearing mode with reduced or disabled self-launch. Do not present it as baseline behavior.
• Vector vanes: proposed directional movement upgrade. Targeting, collision and resource rules must be explicit; it is not permission to ignore server movement validation.
• Cosmetics: brushed silver, dark ceramic, animated chamber markings, earned charms and pressure-ring palettes, with reduced-motion and low-particle settings.

No ballistic magazine is required for the default Spirit contract. Optional recharge choreography must not silently introduce ammunition or a reload cost that the original lacks.

Native acceptance checklist

1. Compare unmodified original movement and target selection on flat ground, slopes, stairs, low ceilings, water and ledges. Record velocity and fall damage, not just apparent jump height.
2. Test Enemy mobs, calm/angry neutral mobs, pets, players and modded entities. Retain the pinned predicate unless a separately named upgrade changes it.
3. Test targets above/below the user, different hitbox sizes, obstruction, full/partial knockback resistance and damage cancellation. Verify push and damage independently.
4. Test held input, insufficient Spirit, modifiers, creative exemptions and server rejection. One accepted use must produce exactly one gameplay burst.
5. Check first/third-person hands, trigger reach, aiming, inspect interruption, swimming/flying and equipment swaps.
6. Measure frame-time impact with many simultaneous bursts; cap cosmetic rings and avoid per-frame allocations/scans. Test shader and renderer compatibility separately.
