Recursive function call

[eugene.litvinov]

Has Unigine limit to recursive calls? We have game dialog, represented as xml-tree, that contain more than 38 nesting levels (If we have less than 38 levels - it's ok, if more - Unigine is crashed). In game logic this xml parses and for all xml-nodes creates class instance, and this dialog presents in script via tree. So, question is, what length of call stack we can use in Unigine script? Thanks.

Please, sent to support@unigine.com a minimal code for reproduction of this issue.

At the present moment the call stack length equals 1024. It will be expanded in 3 times in next SDK release (second half of July).

Works fine under Linux. This seems to be a Windows-specific issue with stack overflow. Our CTO will look into it and sort it out.

Is there any progress in solving this problem?

The problem lies in the fact that it's not a script stack overflow, but instead Windows stack overflow. What happens is a user class constructor calls another user class constructor and then again and again, recursively until the system cannot handle it. The most rational variant for solving this problem is to try to avoid such recursion in your code. On our side, developers are still trying to figure out what can be done.
