FlowKit

FlowKit replaces timers, tick functions and hand-written state machines with one-line latent actions. Start a delay, a ticker, a value timeline or a "wait until" condition from C++ with a lambda, or from Blueprints with an async node, and FlowKit runs it from a game-instance subsystem. Every action is bound to an owner object and is cleaned up automatically when that owner is destroyed.

Each action returns a handle that you can use to pause, resume, reset, stop or re-time it, and every action accepts settings for tick interval, first delay, ignoring game pause or global time dilation, starting paused and a label for stopping groups of actions. Instanced gates (time lock, do once, do N times, do no more than X time) keep only one running action per instance id.

On Unreal Engine 5.8 the same building blocks are also available as C++20 coroutine awaiters, so a whole sequence - wait two seconds, wait for a condition, run a task on a background thread, load assets - reads top to bottom in a single function. FlowKit targets Win64.

FlowKit is part of the Alpha XP utilities collection for Unreal Engine 4.27 and 5.8. Every feature is exposed to Blueprints and C++, it ships with styled HTML documentation, and it is compiled and verified warning-free against clean UE 4.27 and UE 5.8 projects.

Key features

• Delay and Delay Ticks with completion callbacks
• Tickers that run for a duration, forever, or until stopped, with optional tick interval
• Float, Vector and LinearColor timelines with linear, cubic and ease blend functions
• Custom timelines driven by float, vector and linear colour curve assets
• Wait And Execute and While True Execute with optional time-outs
• Time Lock, Do Once, Do N Times and Do No More Than X Time gates keyed by instance ids
• Run a task on a background thread and continue on the game thread when it finishes
• Asynchronous loading of soft object paths with a completion callback
• Handles to pause, resume, reset, stop and get or set the time of any action; stop all,
• Per-action settings: tick interval, first delay, ignore pause, ignore time dilation,
• C++20 coroutine awaiters on UE 5.8: WaitSeconds, WaitTicks, WaitUntil, WaitForFlag,
• Stat groups and Unreal Insights scopes for profiling

Blueprint & C++ API

Every call is reachable from more than one place — pick the entry point that fits your project:

Callable runs when executed · Pure no exec pin, returns a value

+ 1 more FlowKit nodes — full node reference

Events & delegates

Bind these in Blueprint (drag off the object → Bind Event) or with AddDynamic in C++.

Options & enums

Compatibility

One ready-made build per engine version is included in the download — copy the one that matches your project.

Technical details

What's in the download

Quick start

1. Unzip the download and pick the build that matches your engine (4.27 · 5.8).
2. Copy the FlowKit folder into your project's Plugins/ folder (create it if needed).
3. Open the project, enable FlowKit under Edit › Plugins and restart the editor.
4. Right-click in any Blueprint graph and search FlowKit — or include the public headers from C++.
5. Package for your target platform (Windows).
