triggering a timer per particle when inside volume

[seb4d]

Hi !
I have a pointcloud grid of cubes to make a transition, I animated each particle rotation using "Modulate Value Over Time".
Now I want to control triggering when particles are inside a null only, but how do you use a timer to change "Modulate Value Over Time" start time ?

When you need the "Modulate Value Over Time", you can use a "State Machine".
In a normal ICE-Tree, generate the particles.
In a simulated ICE-Tree use the "State Machine".

The first state use the "Test Inside Null" as trigger to the next State and store the current time in a value.
The second state read this value to drive the "Modulate Value Over Time".

This is one of those situation where ICE is much below what it should be: controlling time
Controlling when a simple effects starts and by how much longer is a pain.

There are a node - not much reliable in Motion Tools called Modify over Time.

Also NNois helped me here, note the title: Modulate value over time with relative start frame?

Thanks a lot Face !
I just replicated what you said and it works like a charm.

I agree with you Bullit, controling time seems so difficult in ICE.
