say if you had...
if(m==c) if(d==s)
now by doing this, does it read the first if statement and if it's false stop, or is this for if 1 is true, then if 2 is true?
also
if you had
if(owner==s.owner)
else
if(blah==blah)
else
if(blah==blah)
this is more efficient than doing
if(blah==blah)
if(blah==blah)
if(blah==blah)
right?
and
else
if(blah==blah)
if(blah==blah)
is not the same thing as doing
if(m==c) if(d==s)
correct?

Take a look at ||, and &&.

Yeah like if you want something to meet 2 coniditions before calling true try like this.
This could be used in a shop to both check what the selection was and if they person has enough gold to cover it. if(selection == "sword" && gold > 24) gold -= 25 weapon = "sword" This checks to make sure you have at least 25 gold for the sword and then makes your weapon var a sword. LJR | |
