TDN Tutorial: Flying Vehicle Help
by Toby W. Allen · in Torque Game Engine · 02/13/2006 (4:22 pm) · 3 replies
Hey all, I'm writting a tutorial for TDN - http://tdn.garagegames.com/wiki/DTS/3dsmax/Creating_a_Simple_Flying_Vehicle
I have the full model set out, as shown in the TDN tutorial I've started. What I can't figure out is why the contrails aren't working. I've tried to read as much as I can and all I can see is that you need the nodes (check), the particle system (check) and then make sure it's linked in the vehicle's datablock (check). It's just not doing anything.
Additionally, can someone confirm that the jetnozzle nodes need to be activated by the keyboard command.
I've got some code to get it mounting and unmounting but I can't get these to work yet, which doesn't worry me, what does it the whole nodes not working for the smoke, lights, contrails, etc.. I've checked the emitters, they work.
Any pointers?

Well I have that, which is what I don.t get - I got the nodes places 'Contrail0' and 'Contrail1' with the follow block:datablock FlyingVehicleData(TKFighter)

I can't remember what the precise call is but you need a contrail start speed
umm i haven't gotten in to much else
but hopefully that helps
