I have successfully programmed one action of the robot my FIRST robotics team is working on. We are team 1723. I have programmed the ball push action. In the game, one way to score points, is to push the ball around the track.

//Initialize variables
int startAwesomeTime = 20; //This is the time it takes for the panel to move in or out. (40 is a second)
int awesomeTime = 0; //This will be used as the first half of the countdown.
int awesomeTime2 = 0; //This will be used as the second half of the countdown
int awesomeActivation = 0; //This is so the driver doesn't have to hold the trigger to complete the cycle.
if(p2_sw_trig == 1) //Has the trigger been pulled?
{
awesomeActivation = 1;
}
printf("awsmAct %3d, p2_sw_trig %3d, awsmTime %3d, awsmTime2 %3d \r" awesomeActivation,p2_sw_trig,awesomeTime,awesomeTime2)
if(awesomeActivation == 1 && awesomeTime > 0) //push out
{
relay1_fwd = 1;
relay2_fwd = 1;
relay1_rev = 0;
relay2_rev = 0;
awesomeTime = awesomeTime - 1;
}
if(awesomeTime == 0 && awesomeTime2 > 0) //pull back
{
relay1_fwd = 0;
relay2_fwd = 0;
relay1_rev = 1;
relay2_rev = 1;
awesomeTime2 = awesomeTime2 - 1;
}
if(awesomeTime == 0 && awesomeTime2 == 0) //deactivate
{
relay1_fwd = 0;
relay2_fwd = 0;
relay1_rev = 0;
relay2_rev = 0;
awesomeTime = startAwesomeTime;
awesomeTime2 = startAwesomeTime;
awesomeActivation = 0;
}

I'd say it's awesome, but I never understood C, even when I tried.
But still, it's awesome, because your variables are awesome too. |

All I've got is a heck of a lot of:
void main ()
{
mav(0,-1000);
mav(1,-1000);
freeze(2.5);
mav(0,1000);
ao();
}
It doesn't do much, but it gets the bot out of the opening. (botball) |

Explanation:
It uses 2 pneumatics tubes to push out this panel thing that pushes the ball.
Also, here is the FIRST website. http://www.usfirst.org/community/frc/default.aspx?id=966
The picture of the bots and the red and blue innertubes is from last year's game. |

Yeah, you want something short and easy to spell for your variables. You don't want to be like "awesome-this awesome-that". You should just be able to get rid of "awesome" and have no problems.
Also, NEVER have "name" and "name2" those get really confusing. |

I named them so that they would not possibly have been used before I programmed it. |
