Ran into a Crashing Segmentation fault problem

Hello

So, I created a client. It runs but with some new additional code it’s noticeably crashing. I am looking through the code but I am having no luck resolving. Do anyone have a idea of whats going on or suggestion?

I placed the main code at sourceforge.net/projects/proteu … tenceApps/

The following functions might be the culprit.
void ExistenceClient::CreatePlayerScreenUI() in ExistenceClient.cpp
void ExistenceClient::MainScreenUIHandleClosePressed(StringHash eventType, VariantMap& eventData) in ExistenceClient.cpp
int ExistenceClient::loadplayerMesh(Node * playermeshNode, int alienrace, int gender, int mode) in ExistenceClient.cpp
void ExistenceClient::HandleMouseReleased(StringHash eventType, VariantMap& eventData) in ExistenceClient.cpp

One error I found so far.

What IDE are you using? Have you tried to debug the code as it crashes?

I use Codeblocks with GDB debugging runtime. Also, console GDB runtime debugging.

Before, I wasn’t using it. Now I do. I posted a video of it. The content is lacking detail and lighting but the code is working for what I added.

Hi,
If you want people to read text on youtube you need to drop your screen resolution or make the font bigger.
Good progress on your game too!
