Proper way of doing hit velocity?

@Mr_Robville

I’d guess that the Hit Normal from the Event Hit node could be involved with this, but I can’t seem to make too much sense of it yet, if it’s even related at all.

Aye. You’re looking for dot product whose value goes from -1 <> 1 and, if needed, can be treated as an angle in degrees or radians.

Try this:

It would only print if we hit a wall at 45 deg or so which is dot .7 or thereabouts. In short:

• compare the normal of the hit surface with the direction the character is facing
• stuff behind us is below 0, ahead of you is above 0, and all the values in between

To visualise what dot product is doing:

The Dot Product of 2 directional vectors will be in range of -1 to 1. Anything that’s above 0 is in front of you, anything below 0 is behind (and every other value in between matters, too!) [dot.jpg] I grab all the actors around the player using a Sphere Overlap (as in the original suggestion) and loop through the elements of the array, checking my angles - Dot player’s forward and the direction to each target. For dot values greater than .5 I mark the target, and add that actor to the array…
