In brief
- Start with the editable project, not the JavaScript produced by an exporter.
- Give your assistant one bounded change and a way to check it.
- Keep a working backup, inspect the change, reopen the project and test a fresh export.
Knowing how to ask an AI assistant for code does not tell you whether a purchased game is a good starting point. Before buying, establish which files you can edit, which application opens them and how you will know that a change has preserved the game. This guide provides a practical workflow for that decision.
First, identify what the seller actually delivers
The Cocktail Beach listing distinguishes its editable Construct project, HTML5 export and included backend source. That distinction matters: “HTML5 game” describes a delivered browser experience, not necessarily the original authoring format.
| What you receive | What to establish before editing |
|---|---|
| An editable game project | Required editor version, addons, assets and export permissions |
| A browser export | How to regenerate it from source; do not treat it as the authoritative editing project |
| Backend source, when included | Setup instructions, example configuration and the documented interface |
| Art and audio | Which source assets are supplied and the rights governing changes |
Ask the seller to identify these components for the exact package. Do not infer the contents of a hundred-item portfolio from one product page. The Slotgen catalog links to each original listing; the project planner compares only packages with recorded specifications.
Give the assistant a usable working copy
Construct explains that a .c3p file packages a folder project, and that working in a folder can help with version control and AI tools. It also warns that invalid direct changes can make a project unopenable. Prefer editor-supported changes where practical. Construct project format.
Before making a change, open the supplied project in its required editor and confirm that the unmodified preview works. Keep that original untouched. Record the package name, editor version, installed addons and date in a short project note. Save a separate working copy. If you use source control, make a baseline commit before asking the assistant to edit anything.
Share only the files needed for the task. Remove production credentials, private customer records and payment information from prompts and sample configuration. Check your tool's handling of uploaded source against the rights and confidentiality obligations for that project.
Map the change before requesting code
An assistant should explain where the requested behavior lives before it changes files. Have it distinguish authoring data, custom scripts, assets, generated output and backend logic. An uncertain answer is a reason to consult the package documentation, not permission to invent a file or object name.
Construct's scripting overview is a useful primary reference when a change involves supported scripting. Event-sheet changes and script changes are not interchangeable tasks. Choose the route that fits the actual project.
For a first exercise, choose a small, reversible presentation change: a menu label or a documented display setting. Do not combine it with a new bonus mechanic, a dependency upgrade and a wallet integration. A smaller diff makes it easier to find the cause if something stops working.
A bounded prompt you can adapt
The following is an example request, not a claim that this modification has already been performed on a commercial package:
Goal: update one menu label in this working copy.
First inspect the supplied documentation and identify the source
of that label. Explain the files and editor steps involved.
Do not change payout rules, balances, bet amounts, identifiers,
dependencies or generated export files. Do not invent object names.
Make the smallest supported change. If the edit depends on an
unknown project reference, stop and describe what is missing.
Return a change summary, the checks I should perform, and how
to restore the previous version. Do not label checks as passed
unless they were actually run.
The important part is not a particular chatbot brand. It is the combination of a narrow goal, protected behavior and an observable result. Use the same structure for later tasks, changing the scope and checks as necessary.
Check the result before accepting it
| Check | Evidence to record |
|---|---|
| Inspect the changes | Only intended source and assets changed; unrelated configuration preserved |
| Reopen the project | The editor loads the working copy without missing references |
| Preview the affected screen | New text is correct and fits its controls |
| Exercise neighboring behavior | Navigation, focus, sound and relevant controls still work |
| Create a fresh browser export | The exported version contains the change without manual patching |
| Compare target screens | Record actual desktop and phone dimensions and any clipping |
If a check fails, return to the baseline or isolate the last change before requesting another broad repair. Keep failure notes. A screenshot of the finished label is useful, but it does not prove unrelated game logic is unchanged.
Before choosing a source package
You should be able to answer three questions: can I open the editable source, can I explain where my first change belongs, and can I reproduce a working export? If not, ask for clarification before buying additional assets or promising a delivery date.
Next, read source with or without a backend if you need accounts or wallet integration, or the reskin workflow if your first goal is a new visual identity. These guides describe checks to perform; they are not a security certification or a completed game modification report.
