Tier 7: Postman Character Guide

A Postman character relies on leveraging external script files rather than acting strictly inside engine-based state loops. Postman characters employ standalone batch configurations (.bat) or HTML Applications (.hta) to boot the engine program with customized, hardcoded execution variables determined by the character author. The ultimate mechanism revolves around forcing definitive round wins by completely swapping out or replacing an opposing character's directory map with an completely passive dummy configuration file.

Step 1: Understand the Sub-Tier Implementations

Postman architecture operates on three distinct progressive sub-tiers, scaling up depending on how aggressively the initialization files manipulate the engine environment and local character assets:

• Low Tier: Launches the M.U.G.E.N engine process directly via command-line switches, immediately supplying a pre-configured dummy definition file as the Player 2 (-p2) file path parameter.
• Mid Tier: Retains the base command-line execution framework of the previous tier, but aggressively writes over and replaces the physical asset files of the rival character with empty or harmless scripts in the directory.
• Top Tier: Deploys advanced configuration structures that exploit the command-line reading space of the engine. This allows the script to hijack internal program control flows during initialization, or inject custom runtime payloads dynamically while a match is ongoing.

Step 2: Command Manipulation & Dummy Mapping

The standard framework for a Postman implementation utilizes basic file-swapping or targeted execution arguments to force-load predictable runtime states. Below is an example of a standardized internal Command Definition file (.cmd) structure typical of characters that coordinate with Postman setup arrays to execute base transitions:

;-| Button Remapping |-----------------------------------------------------
[Remap]
x = x
y = y
z = z
a = a
b = b
c = c
s = s

;-| Default Values |-------------------------------------------------------
[Defaults]
command.time = 15
command.buffer.time = 1

[Statedef -1]
[State 0, ChangeState]
type = ChangeState
trigger1 = command = "x"
triggerall = ctrl
value = 0
ctrl = 1

Step 3: Internal State Management Fail-Safes

While the external launch script or execution controller enforces engine parameters, the internal constants (.cns) frequently employ hardcoded self-termination triggers under [Statedef -2]. This ensures that the character rapidly cycles states or forces immediate instantiation loops if conditions are not met, using hard values like lifeset = 0 and forcing state changes away from unsafe indices.

[Data]
life = 1000
power = 3000
IntPersistIndex = 60
FloatPersistIndex = 40

[Statedef 190]
[State 0, ChangeState]
type = ChangeState
trigger1 = 1
value = 0
ctrl = 1

[Statedef -2]
[State -2, Suicide Loop Failsafe]
type = lifeset
trigger1 = life > 0
value = 0

[State 0, Force State Sync]
type = ChangeState
trigger1 = stateno != 5150
value = 5150
ctrl = 0

Sub-Tier Execution Matrix

To safely handle Postman file structures or accommodate their behaviors in custom compatibility frameworks, developers must categorize how their internal files interface with the file system layer versus standard execution blocks.
