Do Your Playtests 100x More Efficiently | Auto-Playtest Bot & Logging

YOU WROTE THE GAME. LET THE BOT BREAK IT.

Playtest Pilot MZ is a bot that plays your RPG Maker MZ game for you at up to 100x speed. It walks every map, talks to every NPC, takes every exit, fights every battle and picks every choice. Then it hands you a report of everything that broke, where it broke and how to fix it.

No AI service. No internet. No code. It lives inside your project and switches on when you press F7 in Test Play.

Setup: Plugin Manager · Code required: none · Engine: RPG Maker MZ

How it works

1. Drop PlaytestPilot.js into js/plugins and pick your Game Type and Difficulty.
2. Start a Test Play and press F7. The bot takes over at up to 100x speed.
3. When it's done, the report opens with every problem sorted by severity, each with a fix.

What it catches

• Script errors, with the event and command that threw them
• Softlocks: stuck events, frozen players, move routes that never finish
• Missing images and audio, before a player sees “Failed to load”
• Transfers to maps that don't exist, or that land outside the map
• Events no one can reach, and switches no event ever turns on
• Message lines that run off the window, measured with your real font
• Dead-end maps the player can't leave
• Difficulty spikes, battles that drag, fights with no challenge
• Economy problems: shops you can't afford, gold with nothing to buy
• Milestones reached too early, too late or never

Program it like IF-THIS-THEN-THAT

The bot follows rules you set in the Plugin Manager. No scripting.

• WHEN every second IF party HP below 40% THEN use recovery items
• WHEN a shop opens THEN buy upgrades and potions
• WHEN party HP below 25% AND no recovery items THEN flag an issue
• WHEN stuck for 20 seconds THEN head to the nearest exit

21 conditions and 19 actions, with cooldowns and fire limits. Note tags like <Pilot: Goal> and <Pilot: Ignore> steer it on any event. A Flag Issue command works as an assert: if the bot ever reaches it, it lands in your report.

The report

• A health score and a “fix these first” checklist
• A design review in three lanes: Visuals, Structure and Functionality
• Coverage for every map, a battle table for every troop, and a progress chart
• Every choice branch it tested, every shop it visited and every rule that fired
• A JSON copy for your own tools

It also scans your whole project without visiting it: every transfer, switch, file reference and line of dialogue.

Built for real projects

• Test Play only by default, so it can never switch on in a game you ship
• Up to 100x speed, with Watch, Lite and Headless render modes
• Seeded decisions, so you can re-run the same path to confirm a fix
• Custom minigame scenes are skipped and listed, never left hanging
• Works with MZ's turn-based and Time Progress battles

What it can't do

• It checks mechanics and flow, not fun. It can't tell you if a joke lands.
• Real-time and action battle plugins need their own controls; pick Game Type “Action / Real-time” and the battle checks are skipped.
• Auto-battle plays a little worse than a careful player, so treat difficulty numbers as a starting point.

Pairs well with

• Playtest Grimoire (free) — a one-hotkey dev toolbar to jump straight to each fix
• Evolving Enemy Powerscaling (free) — smooths out the difficulty spikes the report finds
• Questwright — add the side content a short playtime calls for
• Lifetime Supporter Pass — every plugin in the store, including this one

Install

1. Unzip and copy js/plugins/PlaytestPilot.js into your project's js/plugins folder.
2. In the Plugin Manager, add PlaytestPilot at the bottom of the list and turn it on.
3. Set Game Type and Difficulty under Goals.
4. Test Play, press F7. F6 writes a snapshot report at any time.

Reports save to <project>/PlaytestReports. A sample report is included in the download.

FAQ

Does it need an internet connection or an AI model? No. Everything runs inside your project.

Will it change my game? No. It only plays it. Rule actions marked “assist” (like Gain Gold) are off unless you add them, and the report counts every time one fires.

Does it work with VisuStella and other plugins? It hooks MZ's core functions and is placed last in the list. Screens it can't play are pressed with Cancel, then skipped and listed in the report.

How fast is it really? Up to 100x. The HUD shows the speed your PC reaches; Headless mode is fastest.
