Find Reference For Blueprint Map

Add Find(a ref) function for Maps in Blueprints - Eliminate data copying! Boost performance and simplify operations!

Core Features

Find (Key) → Value Ref + Index

• Retrieve references: Obtain the memory reference of Value via Key instead of a copied value

• Dual data return: also return the Index to enable fast deletion

Remove by Index

• Skip redundant lookups: Delete entries directly using the obtained Index

Technical Specifications

• Open-source code with complete K2Node implementation

Use Cases

• When Map values are complex custom structs, using Find (a ref) avoids returning copies (improves performance) while allowing direct modification of the original Map value - eliminating redundant "modify-then-reinsert" nodes for better readability.

FAQ

Q: Supports other engine versions?

A: Pre-compiled version only works with UE5.4+, but full source code is included for adaptation to any version.

Find Reference For Blueprint Map

在蓝图中为map添加引用版查询，告别数据拷贝！提升性能，简化操作！

核心功能

Find (Key) → Value Ref + Index

• 查询引用：通过Key获取Value的**内存引用**，而非副本拷贝

• 双数据返回：同时获取对应的Index，为快速删除奠定基础

Remove by Index 快速删除

• 跳过二次查询：利用已获得的Index直接删除条目

技术规格

• 源码开放，包含完整K2Node实现

适用场景

• 当map的value是一些复杂的自定义结构体时，使用 Find (a ref) 可以避免返回拷贝，提升性能。同时又能对其直接操作，相当于直接修改该map中对应的value，免去修改后还要插回的多余节点，提升可读性。

常见问题

Q：支持引擎其他版本吗？

A：预编译版本仅限UE5.4+，但插件包含完整的源码，可自行编译适配至任意版本。
