Missile Release delay and lag User Aircraft in SimObject sample

Post by zamirk »

Hi,

When I fire missile sample simobject. Initially, after release from rail, it lags behind then gets away from User aircraft and then goes forward, so some time missile hits own User aircraft due to this lag, I want to remove this lag?
I also changes and increase initial thrust of missile but again this problem come, i don't know how to resolve this problem.

Any one from LM?

Regards,
Zamirk.

Hi Zamirk,

There are extensive configuration options for weapons that can influence the simulation.

Inside your desired weapon's SimObject folder you should see three files:
  • Aerodynamics.xml
  • Guidance.xml
  • Propulsion.xml
See the Learning Center for more information on each of the files:

http://www.prepar3d.com/SDKv3/LearningC ... amics.html
http://www.prepar3d.com/SDKv3/LearningC ... dance.html

You might also want to tweak the simulation frequency settings in the Prepar3D.cfg or aircraft.cfg/sim.cfg:
[General]
min_user_sim_fps=60.0
max_user_sim_fps=60.0
