Help with different commands

Sorry for the title, couldn't think of a better one.
Can someone give me some tutorials on how to update both bumpers at the same time. By the way is there a back bumper?
And how can I update and use Global variable.
if other complicated things might be useful please list them as well since this will be my second competition and I need useful things.
I already read the CBC_V2_manual and I can't understand it
If I understand correctly, you want an if statement to return true if either bump sensor is pressed? A logical OR operation will do this.
if(condition1 || condition2) // condition1 and condition2 should be set to the two bump sensors
{
// Do something here; it will happen if either bump sensor is pressed.
}
There is no rear bumper. The caster wheel has an encoder that can be used as a rear bumper, but accessing it requires a Create firmware hack (trust me, you don't want to attempt this). There are probably better ways of accomplishing what you want... are you trying to line up with a wall? If so, screw a horizontal bar below the rear of the Create, and just back up; you'll align without going over the wall.
I'm not sure I understand your question about global variables... can you elaborate on what you're trying to do?

Well I'm trying to do multiple things such as creating a cliff sensor , and other similar things.
