I need a result of a function, that contains a while loop for example: Code: function sec_func(var param1) { var i = 0; var new_value = 0; while(i < 1000) { i++; new_value += getValue(i); } return new_value; } function first_func() { var my_value = 0; while(1) { my_value = sec_func(50); //no correct result wait(1); } } The above code is just only an example. My problem is, that I dont get the correct result of sec_func, because the function need to much time to give me a correct result. How can I manage that?

Iam very interested, how I can manage that, if I need a result of a function, that contains a while loop and need more time to finish. The problem is, that the script dont waiting for the other functions. My only idea is to make a global variable, save the result of the second function in it and wait in the first function for a value. Or can I use wait_for for that? my_value = sec_func(50); must wait for the sec_func to complete. You know what i mean? @Reconnoiter: Yes of course. Thats only an example. This -> my_value = sec_func(50); is important for me. The script should be wait for a result of a second function. It gives me an incorrect result, cause the loop need more time to run... Oh i hope you understand Sorry for my bad english xD Last edited by NeoJones; 05/14/17 10:11. Errors are the engine of progress. Version: A8 Commercial OS: Win 7 64bit Models: Cinema 4D

Anyway you probably use/used a wait() somewhere in your original 'sec_func' before returning the value. Otherwise is should work. Yes i tried that but the manual says: Quote: A function that contains a wait loop can not return a parameter, because wait() already returns to the calling function before the final return statement is excecuted. And thats my problem. Thats why i think about a workaround. Last edited by NeoJones; 05/14/17 11:00. Errors are the engine of progress. Version: A8 Commercial OS: Win 7 64bit Models: Cinema 4D
