How To Write An Unreal Engine 5 4 Cpp Actor From A Gameplay Brief

Unreal actors fail when they Find in Tick and invent a Jump action. Cache pointers in BeginPlay. Lock 5.4 vs 5.3.

The matching generator is the Unreal Engine 5.4 C++ Actor from a Gameplay Brief (Enhanced Input, No Find in Tick; 5.4 vs 5.3 Fork) (Unreal Engine 5 4 Cpp Actor From Gameplay Brief Enhanced Input No Find In Tick) prompt.

Cache component pointers in BeginPlay not in Tick

Write an Unreal Engine 5.4 C++ actor from a gameplay brief. Use Enhanced Input. Do not Find in Tick. Fork 5.4 vs 5.3 APIs. Start by filling Inputs, not by asking the model to remember last week's run. If a field is blank, write NONE or NOT IN INPUTS and leave it blank through Generate. The card is built so the model cannot honestly invent a number, owner, URL, or command that you did not paste.

Paste these fields before you hit run:

Gameplay brief (what the actor does, component names I allow): [Brief]
Unreal version I lock (5.4 / 5.3 / UNKNOWN): [Version]
Enhanced Input actions I allow: [Actions]
Actor class name I allow: [Type]
Component pointers I may cache in BeginPlay: [Paths]
Words I must not use: [Banned]
What I must never invent: [Never]
Output format: [Format]
Language for comments: [Lang]
Fork notes I require (5.4 vs 5.3): [Fork]

That inventory is the honesty ledger. Anything that does not appear there is forbidden in the draft. If you catch yourself adding a nice-to-have after the run, you are no longer using the card. You are ghostwriting. Put the extra fact in Inputs and run again.

Bind only Enhanced Input actions from Inputs

Generate is numbered on purpose. Do not skip a step because the first paragraph looked done. The early steps exist to stop later prose from smuggling claims.

Walk the Generate list in order:

1. Honesty ledger: Brief, Version, Actions, Type, Paths, Fork, Lang. Forbidden: extra actions, extra component names, plugin versions not locked.
2. Version fork: if Version is 5.4, use 5.4 Enhanced Input includes. If 5.3, do not use 5.4-only APIs; mark them. If UNKNOWN, write VERSION UNKNOWN and do not pick 5.4 by default in comments.
3. Header and cpp sketch: one actor. UCLASS. Cache Paths in BeginPlay only. No Find in Tick.
4. Input: bind only Actions via Enhanced Input. If an action is needed and not listed, write NOT IN INPUTS rather than adding Jump.
5. Refuse: Unity Input.GetAxis, GameObject.Find, GetComponent in Update, Godot get_node in _process.
6. Comments: Lang. Each cached pointer quoted from Paths.
7. Never: invent a GameInstance singleton name, an extra plugin, or a 5.5 API if Version is 5.4 or 5.3.
8. Compliance pass: cut Banned and Never. Print that Version is quoted or UNKNOWN. Format as Format.

If a step asks for a version lock, quote the version from Inputs in the output. If a step asks for a refuse list, keep the refuse list in the published artifact, not in a sidebar you delete. Reviewers should see what the model was not allowed to do.

Honor the 5.4 vs 5.3 API fork

Most failures are the same shape: a missing field gets a confident fill. A conversion rate appears. A Gradle task appears. A flash point appears. A caption appears on a job that asked for slide text only. Your review is to search the draft for numbers, names, and commands, then grep Inputs. No match means cut.

Honor the constraints as hard stops, not vibes:

• Unreal C++ actor from Brief. Not a Unity MonoBehaviour and not a full project.
• No Find, GetActorOfClass, or TActorIterator in Tick.
• Only Actions and Paths named in Inputs.
• Honor the 5.4 vs 5.3 fork.
• No emojis.

When the card says not legal advice, not certification, not an exam dump, or not a caption engine, that sentence belongs at the top of the output. Deleting it to look more finished is how you inherit risk.

Refuse Unity MonoBehaviour and Godot APIs

Finish with the compliance pass the prompt already asks for. Quote the banned-word hits. Cut them. Print character counts when the job has a cap. Print word counts when the job has a budget. List gaps as gaps. Five missing facts are more useful than one smooth paragraph.

Tags on the card (unreal engine 5.4 c++ actor, enhanced input no find in tick, ue 5.4 vs 5.3 fork) are a reminder of the job shape, not an invitation to wander into a neighboring cluster. If you need a different surface, open a different PromptDig card rather than stretching this one.

Fill the card, then run

Replace every bracket. Run on ChatGPT, Claude, or Gemini. Read the ledger first, then the artifact. If the model invents a commit, KPI, DOI, PEL, bid, or logo, discard the run. Tighten Inputs. Run again. Share the filled card that survived, not the first draft that sounded done.
