Portable Wireless Network Monitor

1. Item Introduction

The Portable Wireless Network Monitor is a handheld device that auto-displays a HUD when in your inventory (including any Baubles accessory slot), showing real-time wireless grid energy, EU/t change rate, and GT power tier. No block needs to be placed.

• Handheld device; HUD auto-displayed when in inventory (incl. Baubles slots)
• Real-time display of wireless grid energy, EU/t change rate, GT power tier
• No block placement required
• Uses C→S→C network packet sync; works in both single-player and dedicated servers
• HUD status uses the same four branches as the Wireless Energy Monitor (Calculating / Silent / <1EU / Normal)
• Not stackable (setMaxStackSize(1))

2. Crafting Recipe

Craft the Portable Wireless Network Monitor in a crafting table using this 3×3 matrix:

Slot	Col 1	Col 2	Col 3
Row 1	LV Receiver	Steel Plate	LV Receiver
Row 2	LV Receiver	Screen Cover	LV Receiver
Row 3	Steel Screw	Steel Plate	Steel Screw

Material	Count	Source
LV Receiver (Sensor_LV)	4	GT crafting table
Steel Plate (plateSteel)	2	GT plate forming
Screen Cover (Cover_Screen)	1	GT cover
Steel Screw (screwSteel)	2	GT screw forming

3. Interaction

The portable monitor supports 3 interaction types:

Action	Behavior
Unbound + Right-click	Binds the current player as owner; default HUD mode = 0 (Off)
Bound + Right-click	Cycles HUD mode: 0 → 1 → 2 → 0
Shift + Right-click	Overwrites binding to current player (resets HUD mode = 0)

HUD mode switching runs on the client (aPlayer.worldObj.isRemote) and syncs to WirelessMonitorHUD.setEnabled and setDisplayMode.

First-use tip: When unbound, a normal right-click only performs binding and does not switch HUD mode. After binding, right-click again to cycle HUD display.

4. HUD Modes

The HUD supports 3 modes, switched by right-clicking:

Mode	Name	Example
0	Off	No HUD shown
1	Normal counting	1,234,567 EU
2	Scientific notation	1.23×10^6 EU

5. HUD Content

The HUD shows three lines (top to bottom):

Line	Y coordinate	Content	Field
Line 1 (top)	hudY - 24	Realtime EU/t status	cachedRealtimeEUTText
Line 2 (middle)	hudY - 12	Average EU/t status	cachedEUTText
Line 3 (bottom)	hudY	Grid energy	cachedEUText

GT Power Tier Display

Both average EU/t and realtime EU/t come with a GT-style power tier display, formatted as 2A HV (2 amperes High Voltage). The system auto-upshifts to keep amperage ≤ 4A, sharing the GTTierUtil.formatGTPower implementation with the Wireless Energy Monitor.

Grid Status Four Branches

The HUD grid status display is unified with the Wireless Energy Monitor:

• size < 2: Network status: Calculating... (title cyan §b + calculating orange §6)
• eut == 0: 0 EU/t (Silent) or 0 EU/t (Long-Term Silent, dark gray §8)
• 0 < |eut| < 1: 0 EU/t (<1EU)
• |eut| >= 1: Normal display (value + voltage tier)

6. Key Parameters

Parameter	Value	Description
HUD X coord	screenWidth/2 + 91 + hudXOffset	Based on screen width & config offset
HUD Y coord	screenHeight - 54 - hudYOffset	Based on screen height & config offset (positive = up)
HUD update interval	100 ticks (5 s)	Unified with Wireless Energy Monitor
Inventory scan interval	20 ticks (1 s)	Detects whether the inventory contains a portable monitor
Semitransparent bg color	0x80000000	50% transparent black
Font scale	Config.hudScale	Scaled around (hudX, hudY) as origin
Dataset capacity	61	FIFO (1 initial + 60 × 100t = 300s)
Long-reload threshold	10000 ms (10 s real time)	Above this threshold the dataset is cleared and cold-start triggers

7. Baubles Accessory Support

The portable monitor can be placed in any Baubles accessory slot (BaubleType.UNIVERSAL). Scan order:

1. Main hand
2. Baubles accessory slots (scanned in slot order)
3. Inventory slots 0-35 (scanned in slot order)

Safe fallback when Baubles is not installed: NoClassDefFoundError is caught; the portable monitor still works in the main inventory slots — only accessory slot placement is unavailable.

8. Reload & Rejoin Handling

The portable HUD dataset is not persisted across saves (portable device trait). On rejoin, the dataset resets and is rebuilt via gap detection and the first sample.

Real-time gap detection

Because getTotalWorldTime() does not advance while the player is logged out (cannot detect logout duration), gap detection uses the real-time System.currentTimeMillis() timestamp:

• Long reload (> 10000 ms real time): dataset cleared, cold start triggered
• Short stutter exemption (≤ 10000 ms): dataset preserved, not cleared
• Field lastUpdateRealTimeMs (long, not persisted)

Note: The portable HUD dataSet is a static field, not persisted to item NBT; the longTermSilent flag is also not persisted (resets on logout, consistent with the portable design).

9. World Switch Handling

When a change in mc.theWorld.provider.dimensionId is detected, only UI state fields are reset — the dataSet is NOT cleared (preserving history maintains EU/t continuity):

Reset fields:

• syncedEuStr (synced EU string)
• cachedEUText (cached grid energy text)
• cachedEUTText (cached average EU/t text)
• cachedRealtimeEUTText (cached realtime EU/t text)
• lastUpdateTick (last update tick)

10. NBT Structure

The item NBT structure of the portable monitor:

Key	Type	Meaning
OwnerUUID	String	Owner player UUID (written after binding)
Initialized	boolean	Whether the owner has been initialized
OwnerName	String	Owner player name (for tooltip display)
HUDMode	int	HUD mode: 0=Off, 1=Normal, 2=Scientific

Note: Unlike the Wireless Energy Monitor, the portable monitor does NOT persist measurement history (measurementHistory). HUD history data is a static field, reset on logout, and rebuilt via gap detection and the first sample.
