📖 Instant Pickup Overview

While standard vacuum mode pulls items physically through the air using velocity interpolation, Instant Pickup Mode eliminates travel time entirely. When enabled, dropped items within range are collected into the player's inventory the very microsecond they appear.

Instead of writing risky, crash-prone custom inventory insertion loops, Magnet, Let me get that! implements Instant Pickup by non-destructively expanding the player's native collection bounding box inside vanilla's aiStep() method.

🧩 Architectural Implementation (PlayerMixin.java)

@ModifyVariable(
        method = "aiStep",
        at = @At(value = "STORE"),
        ordinal = 0
)
private AABB ig_magnet$expandPickupArea(AABB pickupArea) {
    Player player = (Player) (Object) this;
    if (!this.ig_magnet$isMagnetEnabled() || player.isDeadOrDying() || player.isSpectator()) {
        return pickupArea;
    }

    Level level = player.level();
    if (!level.isClientSide()) {
        if (ModGameRules.getBoolean(level, ModGameRules.MAGNET_ENABLED) && ModGameRules.getBoolean(level, ModGameRules.MAGNET_INSTANT)) {
            int range = ModGameRules.getInt(level, ModGameRules.MAGNET_RANGE);
            if (range > 0) {
                return pickupArea.inflate(range);
            }
        }
    }
    return pickupArea;
}

Key Engineering Guarantees:

1. Safety Gating: If the player is dead/dying (player.isDeadOrDying()), in spectator mode (player.isSpectator()), or has their personal magnet toggled off (!isMagnetEnabled()), the bounding box is never expanded.
2. Server-Side Authority: Pickup logic executes strictly on the logical server (!level.isClientSide()), eliminating item ghosting and inventory desynchronization.
3. No Double-Movement Conflict: When ig:magnet_instant is true, MagnetMovement.pull() automatically aborts velocity updates so physics and instant collection do not fight for control.
