Networking

Make asynchronous HTTP and HTTPS requests from Lua.

Make asynchronous HTTP and HTTPS requests from Lua without blocking the game thread.

Use ue.http.request to call AI, text-to-speech, web-service, and other HTTP APIs. Responses are delivered on the game thread, so callbacks can safely call reflected Blueprint functions.

Functions

Keep API keys out of script source. Store supported keys in environment variables and read them through ue.secrets.get.

graphics.world_to_screen

Project an Unreal world position into screen pixels.

http.request

Run an asynchronous web request and receive its result on the game thread.
