How to Fix a Broken Roblox Game
Don't rebuild. The chat panel can patch most problems in one message — gaps, lighting, missing parts, lost mechanics.
Your game is mostly there but something is off. Maybe the gap between two platforms is too big. Maybe the lighting is super dark. Maybe a zone is missing. Do not rebuild. Use the chat panel on the right side to patch it.
This guide covers what refinement can do, what it cannot do, and how to write messages that work on the first try.
Refinement vs new prompt
When something is wrong, you have two paths:
Refinement (chat panel)
- Edits part of the existing game
- Keeps what you already like
- Costs fewer credits
- Faster — usually under a minute
- Best for tweaks and additions
New prompt
- Builds a brand new game from scratch
- Loses your current progress
- Costs full credits
- Slower
- Best for changing the game type
How to write a great refinement
Open the chat panel
After your game generates, the chat panel sits on the right side of the screen. It is where you talk to PromptBlox about the game. Type your message and hit enter — the AI will patch the game and show you the new version.
Describe the problem, not the solution
Instead of telling the AI how to fix something, tell it what is wrong. The AI is smart enough to figure out the right fix.
- Less good:"Set platform 4 X position to 30 studs"
- Better:"The fourth platform is too far from the third — players cannot reach it"
The AI will figure out the right distance and apply it. You do not need to know Roblox units (studs) or coordinates.
Reference parts by where they are
PromptBlox tracks every part of your game by name and zone. Help the AI find what you mean:
- By zone number— "zone 3 is too dark"
- By color— "the red platform near the start"
- By type— "the trees in the candy zone"
- By position— "the last platform before the finish line"
One change per message
Sending five changes in one message confuses the AI. It often does two well and forgets the rest. Send one change, wait for the game to update, then send the next one.
Refinement is fast. Five separate messages still only take a few minutes total and you get a clean fix each time.
Refinements that almost always work
These messages tend to produce great results:
- "The lighting is too dark — make it brighter" — common after building cave or dungeon themes
- "The gaps in zone 2 are too big" — fixes unreachable platforms
- "Add a checkpoint between zones 3 and 4" — players will thank you
- "Make zone 4 underwater instead of desert" — swap a whole zone's theme
- "Replace the trees with cactuses" — swap props throughout the map
- "Add a giant boss at the end" — works in obbies, tycoons, and arenas
- "The first jump is too hard — make it easier" — softens the difficulty curve
Refinements that struggle
Some changes are hard for refinement. Try these as a new prompt instead:
- Changing the game type — turning an obby into a tycoon needs a full rebuild
- Doubling the map size — usually breaks the layout
- Renaming or restructuring the whole world — the AI tries to preserve structure
- Adding many new mechanics at once — break it into multiple messages instead
If you get stuck
Sometimes refinement breaks something else. That is okay — there is always a way back:
- Use the undo arrow in the top bar to go back to the previous version
- Reword your message and try again. Different words can produce a different result
- If three refinements fail in a row, the game might be stuck. Start over with a new prompt — write down what you want first so you do not lose your ideas
Real refinement examples
Here are conversations that worked:
You
"The chocolate platforms in zone 2 are too small — I keep falling off"
PromptBlox
[doubles the size of the chocolate platforms, adjusts spacing so they still feel like a challenge]
You
"Add a coin every 5 platforms so players have something to collect"
PromptBlox
[places golden coins every five platforms, adds a coin counter in the corner]
You
"The final zone is bland. Make it the most spectacular part — neon lights, a giant tower, fireworks"
PromptBlox
[redesigns the final zone with neon glow, a tall tower with spiraling platforms, fireworks particle effects]
Common Questions
How is refinement different from making a new game?
Refinement edits parts of the existing game without rebuilding. The chat panel patches only what you mention. A new prompt creates a brand new game and loses your current progress. Refinement is faster, cheaper, and preserves what you already like.
What can refinement fix?
Almost anything that does not change the game type. Layout tweaks, visual changes, gameplay adjustments, new mechanics, prop swaps, lighting fixes. The one thing it cannot do is turn an obby into a tycoon — for that you need a new prompt.
How specific should my message be?
Very specific. "Fix the broken part" is too vague. "The gap between platforms 3 and 4 in zone 2 is too big" works perfectly. Use zone numbers, colors, and positions to point at exactly what is wrong.
Can I undo a refinement?
Yes. The undo arrow in the top bar reverts to the previous version. You can also ask in chat — "put the red platform back" — but the undo button is faster and exact.
What if refinement keeps failing?
After three failed refinements, the game might be too far gone. Copy what you like into a new prompt and rebuild — be explicit about the bits you want to keep. A clean rebuild is sometimes faster than fighting a stuck game.
