Hello All,

I am developing a Minecraft clone in C++/OpenGL on Linux. I am using SDL2 for creating a window and an OpenGL context.

Everything seems to be working - except not all the time. Sometimes when I run my game, it works. The next time I run it, it won't render anything (just the clear color).

You can view the source code of the game on GitHub here: http://github.com/brettmw/cubed

Screenshot of when it's functioning correctly:

And when it's not:

Inconsistent behavior is often the result of missing initialisation, in this example it could be the render state or some variable. So, double check your initialisation first, try to explicitly set a needed renderstate just before starting rendering etc. to narrow down the potential bug.

Thank you Sir.

I hadn't initialised my translation vector in the Transform class.
