Emit pyro outwards (not upwards)

Recommended Posts

Hey everyone, 

 

I have an animated object moving in a sin wave type motion. I am trying to emit smoke outwards from it. At the moment the smoke is just rising in Y which isn't what I want. 

 

Any suggestions? :)

 

+ i made an awful unnecessary diagram, it might help or it might be confuse matters :lol:

Thanks so much for that that hip file is really helpfu!

So that was working but rather than emitting from a line, I am emitting from particles. So I would need the the particles velocity to also point outwards. 

Plugging a scatter into the line and then feeding that straight into the pointwrangle2, I can't seem to get your setup working?

Why not do the scatter after pointwrangle2 and let the points pick up the newly-calculated velocity direction?

My method for calculating if there is a left- or right-hand turn requires a curve, because I am comparing the position and normal direction from the previous and next points. If you want to use particles you need to scatter them after the calculations on the curve like @ryew said.

EDIT: Added a couple of lines to the curve calculation so curves with very sharp turns get correct bending ratios.
