I am making this tetris game in c++ and DarkGDK for my introduction to c++ class.

The movement works, but the computer is having a hard time reconginzing the left and right keys. you need to hold down the key for it to move left or right.

CODE:

//Dark GDK - The Game Creators - www.thegamecreators.com

//the wizard has created a very simple project that uses Dark GDK
//it contains the basic code for a GDK application

//whenever using Dark GDK you must ensure you include the header file
#include "DarkGDK.h"

//Global
int Block_Size=20;
int grid[20][10];
//colors
const DWORD Red = dbRGB(255,0,0);
const DWORD Green = dbRGB(0,255,0);
const DWORD Blue = dbRGB(0,0,255);
const DWORD Magenta = dbRGB(255,0,255);
const DWORD Black = dbRGB(0,0,0);
const DWORD White = dbRGB(255,255,255);
const DWORD Yellow = dbRGB(255,255,0);
const DWORD Cyan = dbRGB(0,255,255);
const DWORD Orange = dbRGB(255,165,0);
const DWORD Grey = dbRGB(177,177,177);
//end colors
//end global

I it is the slow speed of the 2D drawing commands. I used this:

+ Code Snippet

dbText(0, 0, dbStr(dbScreenFPS()));

and it is only getting one frame per second.

You would be better off loading images and making them sprites, it wouldn't be much harder to do and it would be wicked fast.

Okay I updated the code, but really need help finishing it up.

Right now I really need help with the rotation and random shape gen.
