Essentially I working on a 2D platformer as a way to develop a small 2D engine I'm working on that will hopefully help me when creating games in the future with XNA. The game is much like Mario, and like in Mario I need the view to follow the main character while moving non-player characters/enemies off the screen. I was wonderi

They are doing that, but all in unison instead of each changing directions at different times. Its like synchronized ants. Anyone know how to create a truly random number each time the ants use this method

      • Hi, Recently, I'm working on a game project. Most of objects there are represented by billboards with transparent textures. It was gone well until I try to add some fade-in fade-out effects based on vertex alpha value. The problem is that the transparent textures is no longer transparent anymore, while the changing of vertex alpha do fade my objects. I wonder it is because of the wrong setting of

The trouble I keep running into is that the axis keep getting rotated and/or flipped from what's in Max. In order to test this, I have created a model that acts as an axis gizmo, with a cone pointing down the X axis, a Rectangle down the Y and a cylinder down the Z. I have exported the model three different

Some of my shaders use #include directives, so I have implemented the ID3DXINCLUDE interface.
