some thing wrong with kinematics

i use BasicConveyor to make a special conveyor ,most of time it work very well,but sometimes it is not.i also use kinematics, most of code in decision point - oncover.i do not why.

i put" initkinematics(topclampkinematics, topclamp, 0,0);" onreset there is also some problem

Could you please specify what this "special conveyor" is supposed to do and if it is not working correctly, what it is doing then.

if you run a long time that i attatch then you will see the problem

That is just the problem, I want to know from your description if it usefull to spend my valuable time on your problem. I don't want to have to download your model and spend time looking at it and maybe not look long enough or at the wrong place in the code.

If you want me to take a good look you have to do the effort to make it as comfortable for me as possible otherwise I won't do it.

sorry my poor English can not describe it clearly if can use chinese i can describe it clearly

sorry but my Chinese is much poorer then your english so please, take the time to try to explain it in English.

As a general guide for posting:

1) let us know the exact time the problem happens (which means your model run needs to be repeatable - if it occurs visually at different times even though the listed event times are the same then let us know that too)
2) describe what you want it to do at that time
3) describe what it does now at that time (so we can verify the problem)

However in this case I think it's that the red 'pusher' bar moves out of position if you speed up the model enough for frames to be dropped, so this problem doesn't happen at a specific 'event time' - it depends when you ramp up the speed. I'm going to guess this means there's an missing updatekinematic on a key event, since the 'correct' operation seems to rely on ondraw firing.

So I've added code to reset and deactiviate the kinematic and set the objects initial position. I've then added update and deactivate kinematic code on the message - this is the key event that you need an update to happen - you can't rely on the ondraw firing to get the correct position. So far this seems to work okay for me.
