VelocityField + RandomDrift

[chkd...@googlemail.com]

Hi

I want to use VelocityField for particles flowing through some tubes.
This works perfectly.

But now I want to add some random movement. I thought I can use
RandomDrift for that. But I can't get both to work together.
At the moment I use ist like that in my emitter:

var velField:VelocityField = new VelocityField();
velField.field = bmpField;
addAction(velField);

var rDrift:RandomDrift = new RandomDrift(2,2);
rDrift.massless = true;
addAction(rDrift);

I tried it with different priorities but at the moment I use the
velocityfield my particles move straight ahead. Without the velField
they move in random.

Has someone an idea to get e little bit random movement to this?


Thanks.
Christoph

Ah, this problem might be caused by the default priorities of the
actions.
RandomField has a default priority of 0, and VelocityField has -2.
This means VelocityFIeld is executed after RandomField because actions
are sorted according to their priorities.

I think it's more logical to give RandomField a lower priority than
VelocityField. I'll tweak their priorities in the next revision.
For now, you can manually adjust their priorities.

var rf:RandomField = new RandomField(2, 2);
rf.massless = true;
rf.priority = -3; //lower than -2
addAction(rf);

Thanks for spotting this problem.
