Dynamic Melee Weapon Trace

[Walrus Viking]

What would it take to make a dispatched attack do damage to anything the world model touches? Should I be tracing a line from the hand to the end of the weapon each frame (or every other frame)?

Are there any clever optimized ways of doing this?

This is what I've done as a test.

You should do it perpendicular to what it is currently. That way it'll catch things in the path instead of having dead zones.

From one point to the next in sequence.
