Hi
Is it possible to make OnProjectileRicochet hook for RUST. I'm trying to make an analogue of the vis.attack function to draw the trajectories of suspicious projectiles. To do this, I need to save to the array all possible ricochets hitInfo of projectile. I was able to do the calculation only for one ricochet. But it does not work when ricochets are more than one.

Hi Wulf!

Please add the OnProjectileRicochet hook (BasePlayer) in the next umod update or in the development build.

		if (Interface.CallHook("OnProjectileRicochet", this, playerProjectileRicochet) != null)
        {
            return;
        }

Added for the update today. Thanks for the request and sorry for the delay!
