[PIP] 10_RenderToTexture with only one scene?

Virgo

I was wondering if we can achieve PIP in Urho3D and so I added camera control for rttCameraNode_ in sample 10_RenderToTexture.
It worked just find if rttCamerNode_ is in a different scene from the cameraNode_, but if i used it in the same scene, any camera rotation or movement can easily lead to application crash.

Anyone got a solution for this?

using:
Windows 10 Home 1803
Qt creator as ide (not using any Qt library)
visual studio 2017 as compiler

What’s the PIP?
What GAPI is used?
If you have a crash, please show callstack.
I moved everything into main scene in this sample, works fine.

1 PIP is “Picture in Picture”.
Trying to understand terms in 2 and 3, maybe update this reply later.
4 Did you try to rotate or move the rttCameraNode_?

I’m a middle school drop-out doing programming for hobbies, kinda uneducated, sry for my ignorance. xD

Build in Debug mode encountered tons of LNK2038 mistmatch errors

Sry for the late reply! i finally found a way to compile in debug mode. not sure if this is the so called callstack?

Eugene

Still works fine.

strange, i just replaced my RenderToTexture.cpp with your code, and the application just crashed on startup!

Eugene

I tested things on DX9. What API do you use?
Anyway, I recommend to build Urho from source in Debug configuration.
It’s quite hard to guess where and why it crashed.

Im using Dx11, and this is the debug build, finally.

edit:
okay stupid me dont know how to track the one called this function

Eugene

Fixed.

Virgo

Just add a pointer validation check huh? never imagine the solution to my problem could be simple like this

Thanks <3
