Repro Steps
-
Download and install the ShootGame example.
-
Create a new animation blueprint for the third person hero skeleton.
-
Set it up like the following:
- Hit compile.
The negative value seems to be the key.
Results
Editor crashes, producing the following error :
C:/Program Files/Rocket/Engine/Binaries/Win64/
Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\BuildFarm\buildmachine_++depot+UE4-Rocket+Beta6\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 519]
Array index out of bounds: 1 from an array of size 1
If you saved before compiling, unable to open animation blueprint without causing the same error.
Expected
Warning instead of a crash.
Note
The -1.0 to 1.0 random range was just a way of reliably reproducing this issue.
The setup I was using when I came across this issue used a alpha value of 1 - Get Curve Value.
Clamping the value between 0.0 - 1.0 had no effect.
Perhaps it doesn’t like a dynamically set value of zero (0.0) or less?
