vex point wrangle question

[xs2222]

Hi folks,

 

i have a vex question ,

basically i am colouring all points which have a value greater than .005 , and delete ones which does not have the colour , but the ones which have colour should not die at all , even when it reaches a velocity below .005 ?

 

any ideas ?

 

in a point wrangle 

 

 

int @idval ;

int @newVal;

if(length(@v) > .005)

{

@idval = @id;

@Cd = {0,1,0};

@dead = 1;

if((@idval == 0) && (length(@v) == 0))

{

@newVal = @idval;

}

}

 

thanks,

Would something like this work?

 

if (length(v@v) > .005) {
    // Above threshold, set color.
    @Cd = set(0,1,0);
} else {
    // Below threshold, check for color.
    if (@Cd != {0,1,0}) {
        i@dead = 1;
    } else {
        // Was once good, don't kill.
    }
}

Remember, all points will have color (@Cd) even if it is black. {0,0,0} Edited October 16, 2015 by Atom

Hi Atom,

 

thanks for the reply , another tip from Pavel , and did this  before sim 

and works like a charm

 

post solve in wrangle node added these ...

 

i@keepAlive = 0; 

 

if(length(v@v)>.005){ //above threshold 

 

v@Cd = {0,1,0};

i@keepAlive = 1;

}

 // Below threshold, check for color.

else {

        if (@Cd != {0,1,0}) {

        i@dead = 1;

    } else {

        i@keepAlive = 1;

    }

    }
