Specifiers: staticUFUNCTIONBlueprintCallable
Description
Appends a new value to an FDebugFloatHistory sample buffer and returns the updated copy, feeding the debug float-history draw calls.
Caveats & Gotchas
- • Returns a new struct by value rather than mutating in place — you must reassign the result to your stored history variable or samples will be lost.
- • FDebugFloatHistory internally caps the number of retained samples and min/max range; very old samples are dropped as new ones are added.
- • Has no effect on gameplay logic on its own; it only exists to build data for DrawDebugFloatHistoryLocation/Transform.
