Bouncing?

So I'm trying to work out a bouncing ball. I did the usual sphere, made it rubber, turned it physical.... and it rolls just fine, if a little slow. It does not, however, bounce.

Is there anything at all in LSL that might make my poor ball actually bounce like a rubber ball should?

there's a script in the scripting library i'v used befor that makes an object bounce and move towards the closest avatar. pretty cute. might be good for your ball

Hmn... that might work, or at least give a starting point. I would just like to see if have some lift to it, rather than, well, being dropped and watching it sit there.

Try to apply llSetBuoyancy(float buoyancy);
http://www.lslwiki.net/lslwiki/wakka.php?wakka=llSetBuoyancy

You must throw or kick it of course as in the real world

happy scripting

OOOOOH I gots an idea.

on ground collission, apply upward push to the object, each time, diminishing the amount of push.(perhaps based on halving the speed of the collission)

Howszabout this?

CODE

float speed()
{
    vector curVel = llGetVel();
    return curVel.z;
}

default
{
    state_entry()
    {
        llCollisionSound("bc8c684d-d3a8-448b-91ae-0286255e6cea", 0.0);
        llSetBuoyancy(0);
    }

    collision(integer numdetected)
    {
        llApplyImpulse(<0,0,speed() * .5>, FALSE);
    }
}

Oh cute :) Perhaps toss in a llGetMass in there?


CODE


        llApplyImpulse(<0,0,.5*speed()* llGetMass()>, FALSE);




Silly question, does the collision event encompass land_collision events as well? If not, I suppose one could add this at the end:

CODE

land_collision_start(vector pos)
    {
        llTriggerSound("bc8c684d-d3a8-448b-91ae-0286255e6cea", 0.5);
          llApplyImpulse(<0,0,.5*speed()* llGetMass()>, FALSE);
    }

Very cool. I'll tinker with this a bit when I get back inworld :-)

Very cool. Seems to work pretty good, though the movement (not the bounce so much as th erolling of the ball when "kicked";) seems a little rigid -- but that's SL :-)
