Interactive Console Application Runtime Bug [C++]

Malaxiz (24)
Hi.

I am making a "blueprint" for a survival game similar to Cataclysm:DDA.

When my character 'W' is moving vertically, I can press left or right to move horizontally instead. But when I am moving horizontally I can't counteract and move vertically.

I know this is happening because it looks for left and right buttons first. But I don't know how to fix it.

Thanks in advance. And please tell me if this post doesn't belong here, so I can remove it.
