Run nwnScript from outside game - Proof of Concept

[chaoslink]

Failed how? Did you add mutex protection?

[Zebranky]

I did. It still crashed at address 40b736. I think our crafting scripts may be too... resource-intensive... for it to handle, somehow.

IF all that was is just a synchronization problem, then locking the criticalsection/mutex on the hook to the called function and unlocking on its end will do the job. If it still crashes... after several hours of work the first thing that comes to mind is that you did that criticalsection/mutex stuff wrong. Also check for memory leaks. One way to do that is using valgrind(if *nix), but that tends to be ridiculously slow and not many free alternatives in windoze. Another would be to hook the call to malloc/free(and their analogs). I cannot think of any other reason why program could segfault after several hours of work.

Again, memory leak will not be a source of the thing dieing on you, but if you can see it, then it may help you find the source of the problem.

ppl, this task can't be done without breaking/freezing nwserver thread in safe place(such as events loop). if you even lock code part with mutex/cs, data will be unsynchronized. amen.

[XShocK]

I would agree with dumbo. To make sure there are no synchronization issues only pausing the thread can help. But why do you initially want to make such a thing anyway? You could simply synthesize the event yourself. Just make NPC speak, move it to the trap, do anything that would cause the event that fire the script. Not a very fancy way, but can be done in minutes without hacking around, plus quite efficient.

Yeah, my new idea is to hook the main loop. I just have to get the time to sit down and write it...
