Hi,
I'm wondering whether calling of a function/method of a plug-in from a script is indivisible or not.
Maybe it will be better if I show you an example.

Let's suppose there are a method A and a method B in a plug-in.
The methods share a data set (for example two variables).
The method A modifies the data set and the method B reads that data set.
The method A is called in a game main loop and the method B is called when a LeftClick event is trigged.

And now suppose this situation:
The loop has got in the method A and the method has started doing its job.
However, a LeftClick event is trigged during its job.
So, the method B should be called.

I need to have guaranteed that the method B won't be called until the method A has finished its job.

Does WME guaranteed that thing?

I haven't found that information in the documentation but I think it's an important information for developing a plug-in.


I hope I've explained the problem in the understandable way.

Thanks for replies

I am not sure I understand but both plugin methods are called from the WME script, no?

Then the easiest way is to have a variable which will be set to true when you enter method A and back to false when you leave it. This way when you need to enter method B you first wait for end of method A and then you call method B. Or am I missing something?

Yeah, both methods are called from a script.

It's an easy and sufficient solution. However, if the engine guarantees that calling of a function is indivisible, then that's needless.

I just think it's an important information when somebody needs to develop a plug-in.

Everything in WME runs in a single thread, so your plugin method has to finish, before the control is given back to WME. This means it's not possible for two functions to run simultaneously.
If one needs to do some long running action, the plugin method only starts the action (and returns), and the action is then processed in the update event(s).

Great. It's exactly the information I need.
Thanks!

Yes. However, I don't need to do a long running action. I just need to have guaranteed that two methods can't run together.

I can guarantee that
