Variable outside of scope

[coderaider249]

Hi, I have my scene initialized in an if statement. but my main loop is outside the if statement, so I can't access the scene node pointers(or any other variable) in that if statement from the main loop. Is there any way in C++ to use variables that are created inside an if statement out of it?

You might want to review your design instead of trying to look for ugly workarounds
All variables created within a scope get deleted as soon as that scope is no longer valid, unless they were allocated dynamically on the heap, so such a workaround does not exist

You should probably work with classes. Put variables in classes and you can access them anywhere within that class.

Well, wouldn't call it workaround, but common practice: Create the pointer before and init to zero. Then just assign the pointers in your if statement. But as CuteAlien said, it's probably better to give everything a little more structure.

yeah, I tried with creating pointers in the header file although it took the red underlines off but got errors in compile. maybe I want to review the code again.

thanks!

Using classes is different from using globals Maybe you should review your C++ skills before you go on?
