Thread: multiple values ​​in one variable

Hi

You could store the values in an array

So you would turn level.vr1 from a variable into an array

level.vr1[1] = level.a1
level.vr1[2] = level.a2
level.vr1[3] = level.a3

See http://gronnevik.se/rjukan/index.php...Language#toc10

You would still save all the entities into the array and just loop through each iteration in a for() loop and then add the cansee check

Code:

for (local.i = 1; local.i <= level.vr1.size; local.i++)
    {    
         if(self cansee level.vr1[local.i])
         {
         //do code
         }

    }

It will loop through each entity saved in the array until it reaches the end.

The for statement

The for statement is very similar to the while statement, but its declaration is more complex; making it easier to adapt to special cases:

Code:

for ( statement1 ; expr ; statement2 )
 {
   statement
   ...
   statement
 }

At the start of execution of this entire statement, statement1 is executed. At the start of a cycle of the loop the expression expr is evaluated, and while the expression evaluates to true ( 1 ) the statement(s) within the "curly brackets" following the for clause are executed. At the end of each cycle of the loop, statement2 is executed.

So With my example for the level.vr1 array

Code:

for (local.i = 1; local.i <= level.vr1.size; local.i++)
    {    
         if(self cansee level.vr1[local.i])
         {
         //do code
         }

    }

It will first do the first statement which is local.i = 1,
It will then check whether the expressing it true(1) , which is local.i <= level.vr1.size, so its if local.i is equal or less then the size of the array, which is true(1)
If the expression is true , it executes what is inside the brackets, if false, it ends
At the end of the loop , it will do the second statement which is local.i++, which is the same as local.i + 1
It then starts the cycle again until the expression is false(0)

Notice inside the brackets it uses local.i , which changes at each iteration because of the second statement, local.i++ , thus it will cycle through the variables inside the array without needing to re-write each one out.

An interesting thing to note is that for loops are essentially just glorified while loops. They really just do this:

Code:

local.i = 1;
while(local.i <= $player.size) 
{
     $player[local.i] kill;
     local.i++;
}

Since iterating over arrays or collections of variables is such an integral part of programming, the for loop was born just for convenience's sake.
Syntactic sugar as we programmers like to call it. Take the "local.i++", for instance. That's syntactic sugar for "local.i += 1" which in turn is
syntactic sugar for "local.i = local.i + 1".
