Truck & trailer application?

Most likely there are too many groups to handle or your static-mesh is too complex(too many faces), that is usually the problem of freezing on startup.
It's best to make statimesh only the portion of road you really need, and set all non essential groups/components to ignore.As for the camera, well the example script should work quite well, as long as you give it a good curve to follow.
Exporting the animation tho I have no clue about, haven't used that myself, but I know there are alot of threads on these forums about those things.

I know you may not have much experience with exporting, but I can't find much on Sketchy Replay in the forums. Is there a reason that the exported images using Sketchy Replay wouldn't follow the camera? Yesterday I had everything working perfectly, recorded the animation and exported to jpgs. But when I opened the jpgs this morning I see the objects moving, but the camera is located in a random position off to one side, not following the desired object as the on-screen animation showed. Maybe I need to try a screen-capture program to get the animation.
For some reason after that export fiasco, without saving the model, the curve I want the camera to follow has now reversed. Is there a way to force a curve to reverse? It doesn't seem to matter which way I draw it, SP always assumes the opposite end is the beginning. I have tried modifying the speed control script to use the max_distance-frame script you wrote earlier, but adding those lines seems to disable the script altogether.

Ya SP recording doesn't have on option to add camera recording, I guess in this case that is quite crucial... I don't know howmuch work it would be to add this, but I'll have a look at the files.
You could also record it with Fraps, not really ideal but it's the only thing I know.Curves tend to flip directions at random, and not just when created but also when you open/close the file, it can't really be helped because only SU has full control over curves, so scripts need to be adapted.
If you can't fix the script make a model with just the curve in question and your scripted object and I'll fix it up to work. -
Yeah, recording the camera view is really important. I have a screen recorder so if I can get the camera and curves working properly, I think I can get something usable, even if the files can't be modified.
I attached a file with the curve reversed. The model actually contains two curves, an "original" that follows the terrain and a "simplified" that is a roughly straight-line approximation of the original. My first intention was to have the camera follow the actual terrain so I would have a constant 5' eye height, but the one time I actually got everything to work correctly that seemed to create jitters in the camera that I didn't like. So if the simplified curve will be smoother, I'm fine with the relatively constant eye height. I replaced the camera script I had tried previously with the one you wrote for softsoap. I only need the camera to move along the curve. The box pulling the car is only there because I want the view angle of the camera to adjust to the curve as it wiggles near the end, and to help achieve the more accurate eye height described above. Using the steering column is the only way I've been able to get the camera angle to adjust in that manner. Other than that, I have no need for the "car" itself.
I am using your "speed control" script with the max_distance-frame lines added to try and reverse the curve. When I switched the equation to read distance=(frame-max_distance) the camera stayed at the proper end of the curve, but did not actually move as desired.

Alright did a quick fix up of SP files to add camera recordings, but make sure you backup your original files in case this doesn't work for you.
So make sure you backup your /Sketchup/Plugins/SketchyPhysics3 folder, and then extract these two files in there.

The new SP code seems to work fine on a test model. I can't run the simulation on the cameracurve.skp though. I get the attached error. I'll try to download SU7 if you think that might be causing the problem.
-
I copied everything into a new file and it works, but I'm not sure what it's doing. The car travels the right direction down the curve, but the camera watches the car as it goes by from about ground level. Should the camera be moved to the curve, or joined in some way to the car/box? If I read the script correctly, I thought the camera would get the car location whereever it was and follow it.
-
Alright, this is just bizarre. I downloaded the file again, copied everything to a new file, and the simulation seems to run ok now.
The only thing this doesn't do is give me the first-person view that I need. I need the camera view to be coming from the box looking straight down the curve. -
I think I just got it to work! I got rid of the car and the second curve entirely and added this code to the camera On Tick dialogue:
@RedAxis=1
@GreenAxis=0
@BlueAxis=00target=$curEvalGroup.bounds.center
eye=[$curEvalGroup.bounds.center[0]-@RedAxis,$curEvalGroup.bounds.center[1]+@GreenAxis,$curEvalGroup.bounds.center[2]+@BlueAxis]
up=[0,0,1]
Sketchup.active_model.active_view.camera.set eye,target,upI'll post the video once I get it cut. Crossing my fingers that there are no more big hiccups.

Here's the completed animation. Thank you so much for your help, Mr. K.

Would be great if the modifications for camera recording (Mr.K.) could be integrated in to the improved version of SP by AntonS, if it isn't yet.
