Delete Using Density Script Not Working

[Mag8328]

When I spawn a ball using onCollide which will then spawn lots of other balls using onHitByLaser, the script for density does not go all the way through. This would be much easier to understand if you look at the code.

Code: Select all

(e)=>{
    scene.addCircle({
        vel := [0, 40];
        pos := e.pos;
        radius := 0.1;
        color := scene.my.ballcolor;
        onhitbylaser := (e)=>{
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [10, 0];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [-10, 0];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [7.1, 7.1];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [-7.1, 7.1];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [7.1, -7.1];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [-7.1, -7.1];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [3.4, 9.4];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            scene.addcircle({
                radius := 0.1;
                pos := e.pos;
                vel := [-3.4, 9.4];
                color := scene.my.neongreen;
                density := {Scene.my.deleteDensity1}
            });
            scene.addpen({
                pos := e.pos;
                color := scene.my.neongreen;
                size := 0.09;
                fadetime := 1
            });
            density = 0
        }
    })
}

I want the 2nd set of balls to delete after about 3.8 seconds, so I have a forever bouncing circle (total restitution of 1) with the (working) script of

Code: Select all

(e)=>{sim.time > 3.8 ? {scene.my.deletedensity1 = 0} : {scene.my.deletedensity1 = 2}}

When I check the first ball all of the script looks fine. But when I check the second set of balls in the script menu, density = 2 instead of density = {scene.my.deletedensity1}. What am I doing wrong!?

P.S. Thank you standardtoaster for the deletedensity idea here http://www.algodoo.com/algobox/details.php?id=33510

You must use geval to spawn dynamic variables. Here is a link to the thread where it is explained. [link]

One thing that isn't mentioned completely in that thread is that you cannot use formatted code inside geval. You must type it out in paragraph form, which means that it is all very hard to read, so I recommend that you fix any mistakes before putting inside geval.
