Control all objects of a class...

#1 You'll have to store all of them in a set then loop through the set and apply the values individually. For example:

function circles::onAdd(%this)
{
    if (!isObject(circlesSet))
        new ScriptGroup(circlesSet);
    
    circlesSet.add(%this);
}

// Example:
// applyToCircles("setLinearVelocity(10);");
function applyToCircles(%functionCall)
{
    %circlesCount = circlesSet.getCount();
    for (%i = 0; %i < %circleCount; %i++)
        eval (circlesSet.getObject(%i) @ "." @ %functionCall);
}

Something like that will do ;)

#2 Thank you very much I believe this is exactly what I was looking for. I knew it would/was simple.

#3 I changed the onAdd to this

if (!isObject(circlesSet))
{
new ScriptGroup(circlesSet);
echo("circlesSet created...");
}

circlesSet.add(%this);
echo("added");

so that I could see how many times it went thru and added. Everything seems to go well. I adds 4 times which is correct and it creates the circlesSet before it adds so that's correct. It only creates it 1 time which is also correct.

The problem im running into is when I run the applyToCircles it doesn't do anything. So in counsel I ran this

echo(circlesSet.getCount());

it echoed out 0 for some reason its not showing theres anything in there but when it adds it thinks there is otherwise it wouldnt be adding with out creating a new set right?

Im going to try a few things but just thought I would throw this out there before I head off for the night.

#4 Make sure you have the %this parameter in your onAdd function. As one possiblity.

#5 You probably do want to keep track of them in a simset, but an alternative, just for future knowledge, is to get a list of all t2dSceneObject's from the SceneGraph ( t2dSceneGraph::getSceneObjectList() ) then loop through them checking for the classname.

#6 Ok ill try messing around with that. This is just a small script im messing around with so I can change it to whatever we/I need.

#7 Just changing

"new ScriptGroup(circlesSet);"

to

"new SimSet(circlesSet);"

Fixed the problem. Thanks alot!
