› Create a 10×10×4 room with lighting and a concrete texture

spawn Floor (10×10) → spawn 4 Walls → spawn PointLight ×3 (warm/cold/fill) → import texture → create material → apply to meshes → adjust transforms. The whole chain — one command.

› Generate a UI icon texture for a fireball ability via 2D Studio

2D Studio: prompt 'fireball ability icon, fantasy RPG style, 256×256' → get PNG → import → create material → assign to Widget. UI content in seconds, no designer.

› Generate a VFX sprite sheet for an explosion — 8×8 frames, sprite art

2D Studio: prompt 'explosion sprite sheet, pixel art, 8×8 frames' → get sheet → import → create Flipbook → add to Niagara emitter. All VFX content — AI-generated.

› Add a Niagara fire effect to the weapon at the MuzzleFlash socket

2D Studio: generate flame sprites → create Niagara system → create emitter → add modules (color, lifetime, rate) → add renderer → add NiagaraComponent → attach socket. Done.

› Extract this Blueprint's logic into a C++ class with all decorators

read BP via blueprint_to_lisp (DSL) → analyze graph, nodes, variables, events → generate .h with UCLASS(), UPROPERTY(BlueprintReadWrite), UFUNCTION(BlueprintCallable) → generate .cpp → write files → run Live Coding. BP→C++ in minutes.

› Find and fix the compile error in this Blueprint

compile_blueprint → get the exact error (broken pin, missing cast, type mismatch) → blueprint_to_lisp → visualize the graph with the problem node → propose and apply the fix → recompile → success.

› Why doesn't Event OnTakeDamage fire on the player?

get_blueprint_boundary — which C++ functions are visible in BP? → delegate flow — who's subscribed? → find: AddDynamic missing in C++ → generate and add the correct binding → compile.

› Show the full C++↔BP interface for this class

BlueprintCallable: 12 functions (Attack, Heal, Reload…) → BlueprintPure: 4 (GetHealth, IsAlive…) → BlueprintReadWrite: 8 properties → BlueprintImplementableEvent: 3 (OnDied, OnPickup…).

› Why isn't health replicating to the client? Health is always 100%

replication topology audit → DOREPLIFETIME: Health missing from GetLifetimeReplicatedProps! → property declared but not added to the list → generate fix: DOREPLIFETIME_CONDITION(ACharacter, Health, COND_OwnerOnly) → write → compile. Bug fixed.

› Show all RPCs in the project, split by server/client/multicast

24 Server RPC (13 Reliable, 11 Unreliable) → 12 Client RPC → 8 Multicast RPC. Distribution: Combat (14), Player (8), Vehicle (5), Pickup (3).

› Do all replicated properties have RepNotify? Find problems

18 props with RepNotify (OK) → 4 without: Health (CRITICAL — desync), Stamina (HIGH), Ammo (MEDIUM), Score (LOW). Suggestion: add OnRep_Health.

› Analyze DoubleJump: lifecycle, cost, cooldown

class UGameplayAbility_Jump → ActivateAbility, CanActivate, EndAbility → Tags: [Player.Movement.Jump] → Cost: 0 Stamina → Cooldown: 0.5s → GE_SlowFall (2s).

› Show all GameplayTags, the hierarchy and usage

47 tags: Player.State.* (12), Combat.Damage.* (8), Ability.* (14), UI.* (5), Status.* (8). Each: declaration site + references.

› Which GameplayEffects does this ability apply?

3 effects: GE_DamageBuff (Instant, +20%, 5s), GE_StaminaCost (Instant, −10), GE_SpeedBoost (Duration, +15% MS, 5s). Costs: 10 Mana, 15 Stamina.

› Create an AWeapon class with replication and a Server attack

generate .h: UCLASS(), AWeapon : AActor → UPROPERTY(Replicated) Ammo → UFUNCTION(Server) Server_Fire() → .cpp: GetLifetimeReplicatedProps, Server_Fire_Impl → compile.

› Fix the error: 'Health' not declared in the constructor

build log → UPROPERTY exists but isn't initialized → add Health = 100.f → compile OK.

› Add a UFUNCTION Server_Heal with an Authority check

find AHealthComponent → generate UFUNCTION(Server, WithValidation) → HasAuthority() check → Cooldown → compile.
