E2 Entity Discovery, findResult , Loops?

[Dave-X]

Is there a way to create loop structure when using the findBy... and findResult?

For example, if I wanted to add the mass of all the "prop_physics" into one variable.

In other languages I would do this like this.

For X = 1 to findByClass("prop_physics")
  Weight+=findResult(X):mass()
Next X

No.

You cannot loop in expressions (too easy to bog down a server).
But you can achieve the same effect using interval/timers.

Could you give me an example Syranide? How can I go through a list of say, 10 object and find one variable of each object? Like the mass.

Here's an example that will store the masses of everything found in an array.
NOTE: This method will flip the array, so the first mass will be from the last entity found.

@inputs Start
@outputs IsLooping Results:array
@persist Counter
interval(10)
if(~Start & Start){
IsLooping = 1
Counter = NumResults
#do whatever find function here
}
if(!IsLooping){ #Don't do anything else when the loop is being run
#commands
#...
}else{
Results:setNumber(Counter, findResult(Counter):mass())
Counter = Counter - 1
if(Counter < 1){IsLooping = 0} #If there is nothing left, stop looping.
}
