Best AI for coding in Defold?

Rain_Crystal · November 10, 2025, 11:13am

I can open Defold projects directly in Cursor which is very cool. Heard Claude Code is more powerful but has an unfriendly interface. Thoughts?

Try few different and see whatever works for you the best All of the Defold game projects, except obviously your art, 3D or sound assets are text files (all Defold components, scripts, modules), so you can open them in any Text Editor, including Cursor or VS Code with some plugins and LLMs can read them and help you writing and updating them. Afaik, Claude Code is a CLI tool, so if it’s unfriendly to you, I recommend plugins like Windsurf or Codex, that open in VSCode in a tab. For best results - make small tasks, explain stuff, point out to documentations. Bear in mind those are pre-trained transformers, but nowadays most of them have web access. They might though sometimes “imagine” incorrect API and use it, so double check it. There is also “llms-full.txt” file for better context in working with Defold:

github.com/defold/doc

Add `llms-full.txt` file to help LLM systems better understand and utilize docs

"AI" tools for programmers like Cursor can index the documentation of a particul…ar project and this helps a lot to improve the context of the LLM. These tools can also index entire sites, but as it usually happens, the result is not very good, because the result includes a lot of unnecessary information. This also applies to the Defold documentation site. Since the end of 2024, the idea of creating one large file with all the project documentation in a simple format (Markdown) that can be given as context to the LLM has gained popularity. **Request:** add the `llms-full.txt` file to the Defold documentation site.

I think cloude code give high quality code and less error prone as compared to cursor. And yes you are it has an unintuitive interface as it is not an IDE like cursor but a node based terminal appplication, which make it a bit complex as compared to cursor.

Here’s the best way to do it (and cheapest).

Buy Claude ($20/month). Use claude code in VS Studio (with Defold Kit).
Also use ChatGPT Codex (get it by signing up as a business…just need to buy two accounts).

I use them all. And when codex runs out of tokens I switch to my 2nd ChatGPT account.

But both Codex and Code work great, then they get stupid…when that happens I switch to the other.

And I’ll put them against each other. I’ll have them refactor my code or suggest improvements. Then take that output to the other and say “This is was Claude Code says I should focus on…do you agree?”.

I think cloude works great out of all the LLMs and accurate IMO, but it is good up to an extent but after that it’s getting lame.

Also, I added https://defold.com/llms.txt

It seems like it works:

Perfect! I added an instruction to Defold Guru to refer to it. And updated recommended model to 5.2 (someone asked about it, but I can’t remember where):

Actually github chat with copilot is hands down the best way. It gives your all the models for only$10 per month.

It has the latest Gemini Claude GPT models and several more.

But isn’t it browser-only? Or there is a solution that you can use it “locally” with your IDE?

Xev · January 21, 2026, 8:27am

I think they mean the Github Copilot Chat extension in VS Code.

d954mas · January 21, 2026, 8:29am

Codex is awesome. Big limits, and not bad code:)

schlista · January 21, 2026, 1:54pm

Vscode works great.

BTW: the reason Github Copilot Chat via VSCODE is so good, often times one AI just doesn’t “get it”. So then you can switch to the others. Gemini tends to suck for me but when all others fail it has came through in a pinch. Grok Fast 1 is actually quit great (when it’s great) but then it’s like gemini and not good at all.

ChatCPT Codex Max and Claude Opus are the best.

But the best thing is they are all available in Copilot for GitHub Via VSCODE.

I use defold kit in VSCODE and it works very well. But often times I still run the Defold IDE to test. If you use claude opus it’s cool as shit if you let it it will run the program via defold kit and then read the logs and even move the character in the game scene!
