Hell

I’m working on AI and many confusions.

In project is pawn sensing and noise on my side. AI see me well, this is no problem. But when creating noise, AI can hear me only when can’t see - for example, when player pawn is behind wall. This is normal? I have simple debug with print string, when making noise face to face any reaction, when behind wall etc, they hear excellent!

Thank’s!

This is because you didn’t change the “ **Peripheral Vision Angle** ” parameter value of the **PawnSensing** Component.You can change the value to 360.
