Info

This extension adds all Unreal Engine reflection func params to code completion.

• Supports Unreal versions 4.27.2, 5.1.1, 5.2.0
  • Extension will work with any Unreal version.
  • Download the version which matches your version the closest
  • Note: If your version doesn't match, some paramaters, that you add to your code, may cause Build to fail
• Uses parsed params from the Unreal source code
  • Also contains parsed parameter documentation from source code
  • Manually added a couple missing params from UPROPERTY as well as params from UMETA and UPARAM
• This uses the VSCode snippets functionality
  • This allows for parameter filtering see below
• Works with all VSCode extensions
  • VSCode + Microsoft C++ extension (See my fixes extension)
  • VSCode + clangd extension (See my unreal-clangd extension)

Different Versions Warning

You can install multiple versions of this extension

Because of this you should disable these extensions globally and only enable them for the Unreal Project workspaces you want.

Note: If you don't you'll have way too many code completions for parameters

Branches

This github contains branches that lists all parameters the extension/Unreal version supports

Filtering

Using snippets allow rudimentry filtering. Type the keyword + a space to filter code completion for parameters for a specific function.

When done correctly code completion will list all parameters for the keyword you specify.

Note: Meta parameters have their own filter keyword. Some may show up when you type other keywords but it won't list all of them.

For example:

• If you type 'up ' (remember the space) it'll list all the normal parameters for UPROPERTY.
• You'll need to type 'mup ' for a list of all meta parameters for UPROPERTY.

Here's a list of the specific filter keywords for all the reflection functions:

Note: You type these without quotes. Remember the space after. Capitalization doesn't matter.

• UPROPERTY: 'up ' , meta: 'mup '
• UFUNCTION: 'uf ' , meta: 'muf '
• UCLASS: 'uc ' , meta: 'muc '
• UINTERFACE: 'ui ' , meta: 'mui '
• USTRUCT: 'us ' , meta: 'mus '
• UDELEGATE: 'ud ' , meta: 'mud '
• UENUM: 'ue ' , meta: 'mue '
• UMETA: 'um ' , meta: 'mum '
• UPARAM: 'uparam ' , meta: 'muparam '

Note: All filter keywords appear after the parameter during code completion. For example for the UPROPERTY ToolTip parameter:

ToolTip                                 - mUP [PropertyMetadata] rflparam UE5
