if...then statement question

GundamSV7

Hey, I was wondering how I'd go about coding the statement "if $enemy[x] is NOT within -2 or +2 of $user[x], then do not attack". $enemy[x] is the enemy's x coord and $user[x] is the user's x coord. So basically, I don't want the player to be able to attack if the enemy's too far away. I thought about:

if($enemyinfo[x] != -2<=$userinfo[x]<=2) {
echo "no";
}

but that doesn't quite make sense...

It's OK to use more than one condition. Sometimes, it's impractical to combine it all into one conditional... My only question, though, is this; Don't you need to account for the 'Y' coordinates too? Also, do you need to account for diagonal distances too? This sounds like it is more than just comparing the x values, but it's your program, so you know what you need it to do. This should help you along. Let us know if you need further guidance.

if($enemyinfo[x] < ($userinfo[x]-2) || $enemyinfo[x] > ($userinfo[x]+2)) { 
echo "no"; 
}

cool, thnx for the help! and ya, I do have y coords too, but I figured if I knew how to do the x, I could do the y as well, but just in case, is it something like this:

if(($enemyinfo[x] < (userinfo[x]-2) || $enemyinfo[x] > ($userinfo[x]+2)) && ($enemyinfo[y] < ($userinfo[y]-2) || $enemyinfo[y] > ($userinfo[y]+2))) {  

echo "no";  

}
