How UnrealPilot Verifies Every Change with AI-Generated Tests

The Trust Problem with AI Code

AI can generate code. But can you trust it? You've probably had an AI write something that looked correct but failed at runtime. Or subtly changed behavior in ways you didn't notice until later.

UnrealPilot solves this with systematic verification. Every change is planned, executed, tested, and validated—automatically.

The UnrealPilot Workflow

When you ask UnrealPilot to make a change, it follows a strict process:

1. Plan: Understand what needs to change and how
2. Pre-flight: Check for potential problems before starting
3. Execute: Make the changes
4. Generate Tests: Create verification tests for the changes
5. Validate: Run tests and check results
6. Rollback or Commit: Undo if tests fail, proceed if they pass

What Gets Tested

Blueprint Changes

When UnrealPilot modifies a Blueprint graph:

• All wire connections are verified intact
• Execution paths match the original logic
• Variable types and pin connections are valid
• The Blueprint compiles successfully

For functional changes (adding new logic), UnrealPilot generates tests that verify the expected behavior.

Actor Spawning

"Spawn 50 enemies around the arena"

UnrealPilot verifies:

• Correct number of actors spawned
• All actors are in the specified area
• No actors overlap or clip through geometry
• All actors have expected components and properties

Property Changes

"Set all lights to intensity 5000"

UnrealPilot verifies:

• All target actors were found
• Property values were actually changed
• No unintended actors were modified

Pre-flight Checks

Before making destructive changes, UnrealPilot checks first:

"Delete all actors tagged 'Temporary'"

Pre-flight:

• How many actors will be deleted?
• Are any of them referenced by other systems?
• Will this break any Blueprint references?

You see the impact before anything happens. If it looks wrong, cancel. If it looks right, proceed with confidence.

Rollback on Failure

If tests fail, UnrealPilot doesn't leave you with broken code. It automatically rolls back to the previous state and tells you what went wrong:

Change failed validation: 3 wire connections broken in event graph.
Rolled back to previous state.
Issue: Node "Custom Event" pin type mismatch after modification.

You're never left debugging AI-generated problems. Either the change works, or you're back where you started with an explanation.

Test Generation Examples

For a Health System

"Add a TakeDamage function to BP_Character"

Generated tests:

• TakeDamage(10) reduces CurrentHealth by 10
• TakeDamage(0) doesn't change CurrentHealth
• TakeDamage(more than CurrentHealth) triggers OnDeath
• CurrentHealth never goes below 0

For Material Changes

"Add a roughness parameter to this material"

Generated tests:

• Parameter node exists with correct name
• Parameter is connected to Roughness output
• Material compiles without errors
• Default value is within valid range (0-1)

Why This Matters

Most AI coding tools are fire-and-forget. They make changes and move on. The burden of verification falls entirely on you.

UnrealPilot shifts that burden. You describe what you want. UnrealPilot makes the change AND proves it works. If it can't prove correctness, it tells you instead of silently breaking things.

This systematic approach means you can trust UnrealPilot with larger changes. Refactor a 500-node Blueprint? UnrealPilot verifies every connection. Bulk-update 100 actors? UnrealPilot confirms each one.

Not Just Unit Tests

UnrealPilot's verification goes beyond traditional unit tests:

• Structural validation: Graphs are well-formed
• Reference checking: No broken links
• Compilation tests: Everything builds
• Behavioral tests: Logic does what's expected
• Regression tests: Existing behavior preserved
