Ladders can't be climbed in 3.1.3

[Cheo]

Hi, an error gets thrown when we try climbing one of the ladders in the climbing demo scene in UCC 3.1.3 :

Here's the error :

Hope this can be fixed, thanks.

Thanks, if you add a m_DetectedObject != null to that if statement just before the line that throws the error it should fix it.

 

[Cheo]

Yes, that fixes it.

Thanks, if you add a m_DetectedObject != null to that if statement just before the line that throws the error it should fix it.

Will this be addressed in a future release?

Yes, it will be in the next update.
