Sequencer - Get value at time

[Phizzzzzz]

@ThiloN1987

Maybe they changed it. UMoveSceneFloatSection has a GetChannel() member and in the channel (FMovieSceneFloatChannel) has Evaluate(FFrameTime InTime, float& OutValue).

If you have the float section, you maybe could evaluate it with

const FMovieSceneFloatChannel& Channel = FloatSection->GetChannel();
int32 FrameNumber = 0; // the frame to evaluate the curve at

float Value;
bool Success = Channel.Evaluate(FFrameTime(FrameNumber), Value);
if (Success)
{
// successfully evaluated. Value has the curve value.
}

Thanks for your reply!

I implemented those lines and it builds successfully. Evaluate seems to be exactly what I need!
When I put the node in a Blueprint though, Unreal crashes when I compile it:

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Build\++UE4+Licensee\Sync\Engine\Source\Runtime\Core\Public\Containers/Array.h] [Line: 674] Array index out of bounds: 0 from an array of size -109292494

Is Evaluate using and internal array that is faulty in some way? When I remove the Evaluate-line the crash doesn’t occur, so I think the rest of the script is OK.
