Hi. I have to do a job in a class in a thread. But it seems that threads and classes do not play well. Specifically the class that carries out the action "do_blocking()" in the example below is created as uninitialised as if it is a completely new class TestClass { int canary; TestClass() { canary = 1; } void do_async() { log.message("TI: %s\n", typeinfo(this)); log.message("Canary value = [%d]\n",canary); thread("do_blocking"); } void do_blocking() { log.message("TI: %s\n", typeinfo(this)); log.message("Canary value = [%d]\n",canary); } }; The output from running "TestClass tc = new TestClass(); tc.do_async()" is 16:29:29 TI: TestClass 0000000007EB7150 (196608:0:0) 16:29:29 Canary value = [1] 16:29:29 TI: TestClass 0000000000000000 (196608:-1:-1) 16:29:29 Canary value = [0] What I desire is that it is possible to launch a thread in a class and have that thread operate on the same object that spawned it, but it does not seem to be the case here. Am I missing something simple?

Hello ! I am currently seeking for a scripting functionality that I can't really find. Problem: I would like to share a user class across each World scripts. This class could handle and save some attributes for example (it is like some kind of "singleton" pattern). According to the documentation, I have foundb(from https://developer.un...stem.get_string) : variable engine.system.get(string var) Description Returns a variable from the system script. Instances of user-defined classes cannot be requested in such a manner. Arguments string var - Variable name with a namespace, if needed. Return value Requested instance. As you could read : Instances of user-defined classes cannot be requested in such a manner And it is true, trying to share user class in such a manner lead to Unigine crash. Could you please give me some tips on how to achieve that kind of task ? (I believe I could write my own C++ plug-in that will expose my user class to Unigine script and ensure "singleton" pattern but I think it is a bit too "complicated" only for that) Thanks for reading me !
