FAQPage Schema

How do I trigger Unreal Engine Live Coding compilation automatically?▼

Unreal Engine Live Coding compilation is triggered by sending a Ctrl+Alt+F11 keystroke to the running Unreal Editor process. This automates the hot reload process without needing to manually restart the editor for C++ changes.

What is the best way to hot reload C++ code in Unreal Engine without restarting the editor?▼

The best way to hot reload C++ code without restarting the Unreal Engine editor is to use Live Coding. By sending a Ctrl+Alt+F11 keystroke to the foreground editor window, you can compile minor code adjustments and see effects instantly.

Does triggering Unreal Engine Live Coding require the editor to be the foreground window?▼

Yes, triggering Unreal Engine Live Coding requires the editor to be the foreground window. The automation ensures the Unreal Editor process is in focus before sending the Ctrl+Alt+F11 compilation command to prevent keystrokes from hitting unintended applications.

When do I need to use Live Coding instead of a full editor restart for C++ compilation?▼

You need to use Live Coding when you want a streamlined development loop after making small C++ changes. It avoids the time-consuming process of a full editor restart, allowing rapid iteration by compiling code directly in the running Unreal Editor.

Why is my Unreal Engine Live Coding hot reload not working when triggered externally?▼

Unreal Engine Live Coding hot reload may not work if the Unreal Editor is not the foreground window or if Live Coding is not enabled in the editor settings. The editor must be open and in focus to successfully receive the Ctrl+Alt+F11 compilation keystroke.
